[00:00] Hi, my name is Ramsey Salim.
[00:04] And as you can see, there was a bit of a technical issue there.
[00:06] There's a bit of a delay line between launching the presentation on the webinar and it going live.
[00:15] Yeah, so anyway, so this is the first webinar and it's one in multiple series.
[00:21] So hopefully in the next ones, near the technical problems will be kind of ironed out there.
[00:23] And so this is the series is the first for your practice and it's about advanced packaging.
[00:30] And especially we'll be looking at stepping into the world of advanced photonics for this this episode today.
[00:40] With me, it is Francesco Flores.
[00:43] I see, hi everybody.
[00:45] Introduce yourself, Francesca.
[00:47] Yeah, my name is Francesca Flores and I'm working in the photonics packaging group at International Institute in Cork, Ireland.
[00:56] And I'm now in charge of the research in
[01:00] and I'm now in charge of the research in the group and I'm starting this new the group and I'm starting this new adventure taking care of the trainings.
[01:06] adventure taking care of the trainings and teaching programs for our practice and teaching programs for our practice very exciting yeah so today the.
[01:15] very exciting yeah so today the presentation or the webinar it's it's one presentation but two talks so first.
[01:18] one presentation but two talks so first will be a talk about stepping into the.
[01:26] will be a talk about stepping into the world of advanced photonics looking at what that entails.
[01:29] what that entails how do you go to a prototype from a device what is device and a package look like why do you want photonics packaging.
[01:35] like why do you want photonics packaging and in the second part and Francesco will be talking about give us examples.
[01:39] will be talking about give us examples of what you can expect in future webinars in terms of go into the detail.
[01:44] webinars in terms of go into the detail of how to do specific things in photonics packaging a but also some of.
[01:51] photonics packaging a but also some of the training programs and we'll touch on what will be happening in 2020 in terms.
[01:53] the training programs and we'll touch on what will be happening in 2020 in terms of training programs and future webinars.
[02:00] of training programs and future webinars at the end will be a Q&A session.
[02:03] so the Q&A session if you would if you have questions just fire emails to Europe practiced or gateway at Tyndall.
[02:11] ie so it's at the bottom of this as you can see it there at the bottom.
[02:15] there and we'll collect the questions and answer them in a Q&A session at the end.
[02:20] but yeah so let's step into the world of advanced photonics packaging.
[02:26] and and yeah so if you do a google or go online and do a search online for advanced photonics packaging.
[02:35] there's so much information in there you'll find books on the topic.
[02:41] you'll find tools and machines that will do photonics packaging.
[02:43] you'll find devices you'll find plug-and-play and prototypes so there's a lot there.
[02:49] but maybe what is lacking is at the moment and some sort of structured approach to help people understand how do they take their chip design and bring it right through to a
[03:02] design and bring it right through to a prototype where they can test something.
[03:04] prototype where they can test something out and then and then why is this little.
[03:08] out and then and then why is this little photonics package why is it important.
[03:10] photonics package why is it important why is that something that I should.
[03:12] why is that something that I should think about when I'm making my design or.
[03:13] think about when I'm making my design or I'm trying to figure out how to bring my.
[03:15] I'm trying to figure out how to bring my prototype or product in to the market.
[03:18] prototype or product in to the market well really photonics packaging is in.
[03:23] well really photonics packaging is in the heart of photonics so photonics for.
[03:28] the heart of photonics so photonics for the last 25 years has been such a.
[03:30] the last 25 years has been such a disruptive innovative technology it's.
[03:33] disruptive innovative technology it's transformed and is continually to.
[03:36] transformed and is continually to transform the medical and sector where.
[03:39] transform the medical and sector where people used to have to travel long.
[03:41] people used to have to travel long distances to get to hospitals or medical.
[03:44] distances to get to hospitals or medical centers where they'd get this certain.
[03:46] centers where they'd get this certain diagnosis done and whereas now you can.
[03:49] diagnosis done and whereas now you can get certain machines that will use.
[03:51] get certain machines that will use photonics packaging at the heart of it.
[03:53] photonics packaging at the heart of it to have handheld devices and these.
[03:55] to have handheld devices and these handheld devices can go to the patient.
[03:57] handheld devices can go to the patient in their home get the test done and the.
[04:01] in their home get the test done and the medical expert has the results so.
[04:03] medical expert has the results so straightaway so there's an impact in medical sector and that's very evident.
[04:08] and it's growing at the moment there's also the Internet of Things and 5g data comes in telecoms where photonics again is at the heart of the revolution in there.
[04:20] so automated vehicles are using photonics and by default using photonics packaging to to enable the revolution in automated vehicles looking at how the web 2.0 is got that increased demand from the user for more more data more capacity and that is transit translating into photonics solving that problem for people.
[04:47] so there is more capability for machines to talk to machines people to upload more data load up their youtubes their instagrams their Facebook's etc and but also other sectors the security and safety sector for example drones are
[05:04] and safety sector for example drones are playing a big role now and photonics
[05:07] playing a big role now and photonics accessories are so much now they're just
[05:10] accessories are so much now they're just so prevalent for drones where in Italy
[05:14] so prevalent for drones where in Italy there is a lot of seismic activity and
[05:16] there is a lot of seismic activity and what they're doing now is for safety and
[05:18] what they're doing now is for safety and security they send out drones with lidar
[05:21] security they send out drones with lidar zone them to find or to map areas and to
[05:26] zone them to find or to map areas and to find other survivors where should a
[05:29] find other survivors where should a responders go to where can they find sit
[05:32] responders go to where can they find sit so they can find people intelligently
[05:33] so they can find people intelligently and safely also they're getting used
[05:36] and safely also they're getting used drones in agricultural that technology
[05:39] drones in agricultural that technology revolution where photonics is there
[05:41] revolution where photonics is there again at the heart of it so
[05:42] again at the heart of it so spectrometers are attached to drones and
[05:47] spectrometers are attached to drones and they're set out to again map and find
[05:50] they're set out to again map and find out get more well get more information
[05:52] out get more well get more information from the fields in the arable land and
[05:54] from the fields in the arable land and what insects are there what pesticide
[05:56] what insects are there what pesticide levels are there a material get get an
[05:59] levels are there a material get get an idea of the substances that are in the
[06:02] idea of the substances that are in the air and then lay on the plants and all
[06:04] air and then lay on the plants and all the information that's coming back to
[06:05] the information that's coming back to farmers and they're able to use that.
[06:07] farmers and they're able to use that information to feed back into their into their agricultural process other aspects.
[06:13] as well that are not on here on the slide you can think about very easily is VR augmented reality so photonics is is at the heart of that change in that innovation.
[06:22] so how do you get your chip to become a prototype and how do you get your chip to become a if a package that can be plugged into your prototype on your product and you can then try it out and test it out.
[06:41] well at the beginning you get your chip and your chip is this it's going right pianet it's got your clever designs in there and how you're gonna manipulate the signal and so but then when you first get it the first thing you probably do is what I would do at least is I'd do a visual inspection check it out I'd probably take it under the microscope have a closer look check out the design I've done but the next thing we want to do is now evaluate its performance is it
[07:05] do is now evaluate its performance is it going to do what or expecting a tutorial
[07:08] going to do what or expecting a tutorial and there's a couple of ways of doing that
[07:09] and there's a couple of ways of doing that one I can plug it into my prototype
[07:11] that one I can plug it into my prototype or my product but I need some sort of tectonics packaging to be able to plug it in
[07:15] tectonics packaging to be able to plug it in
[07:16] it in I can't just take the die and put it into the into the prototype or I need to set up something on a on a workbench
[07:23] set up something on a on a workbench bring a laser bring some fiber or put a detector there to pick up the signal so
[07:28] detector there to pick up the signal so you're trying to align now your laser to your chip it does the processing of the signal and I need to extract that information
[07:34] signal and I need to extract that information and you need the photo detector to extract the information from the chip
[07:38] the chip and this can be it can be done in an experimental lab but then you have to worry I have to focus on and think about are you aligning it to the best possible position
[07:46] to worry I have to focus on and think about are you aligning it to the best possible position are your probes down correctly
[07:50] possible position are your probes down correctly are you getting the right information from your chip or is the experiment compromised because of an alignment that you may have there
[07:56] experiment compromised because of an alignment that you may have there
[07:59] alignment that you may have there whereas photonics packaging you've got experts that are putting these things together and it's fixed in position so
[08:03] experts that are putting these things together and it's fixed in position so
[08:06] together and it's fixed in position so every time you repeat the experiment in
[08:08] every time you repeat the experiment in August marks is the same it's the same
[08:09] August marks is the same it's the same repeatable and result but then also you
[08:13] repeatable and result but then also you can also just take that photonics
[08:15] can also just take that photonics package and plug it into your product or
[08:16] package and plug it into your product or plug it into your prototype and we're
[08:18] plug it into your prototype and we're able to test you for that straight away
[08:20] able to test you for that straight away so that's the idea of a chip to a
[08:23] so that's the idea of a chip to a package but how does that chip become a
[08:25] package but how does that chip become a fat or naked well the first thing you
[08:28] fat or naked well the first thing you want to think about it is well you've
[08:30] want to think about it is well you've got housing or a base plate you're going
[08:34] got housing or a base plate you're going to put everything onto something or into
[08:36] to put everything onto something or into something and you need to think about
[08:38] something and you need to think about the constraints of that
[08:40] the constraints of that and is it going to be a pluggable what
[08:42] and is it going to be a pluggable what does that need to plug into and so
[08:44] does that need to plug into and so what's the mechanical criteria for it a
[08:47] what's the mechanical criteria for it a are their thermal implications to it and
[08:49] are their thermal implications to it and will it do some passive cooling means
[08:52] will it do some passive cooling means you've got some air coming down below it
[08:53] you've got some air coming down below it or is do you need active cooling too or
[08:57] or is do you need active cooling too or active heating or active even thermal
[09:00] active heating or active even thermal management so you've just keeping in a
[09:02] management so you've just keeping in a specific temperature all the time it
[09:04] specific temperature all the time it could be room temperature but it could
[09:05] could be room temperature but it could also be higher 70 degrees it could be
[09:08] also be higher 70 degrees it could be lower and so in that case you put an attack now.
[09:12] so the tech would be in place and this tech you have to also think about well what temperature you wanted to run at.
[09:19] what's the power management that you'd want to be doing here to control your performance of your chip.
[09:25] now the best thing is if you've got tech in there is to try and get your chip as close as possibly on it.
[09:29] so if you've got your pick then your pick is going directly on that tech to keep that temperature exactly where you want it.
[09:37] the further away it is from the tech the more power you need in there to control the temperature of the package.
[09:41] and the more implications there so now you've got your circuit on the tackle if you need to get light into it I'm like after that you need to read and write and then and get the light in there so.
[09:54] the next thing somebody think of in terms of photonics packaging or the assembly process is that the laser is getting placed onto the neck there could be depends here now on your coupling scheme but also on your chip is it silica is it silicon is it can you.
[10:09] silica is it silicon is it can you phosphide are you using grating couplers?
[10:12] phosphide are you using grating couplers edge couplers what is it you're using?
[10:14] edge couplers what is it you're using how are you going to the light from your laser into the chip do you need some more information there from energy it kind of a flip chip on there so these are some constraints and things to think about but also know that you've got your construction you need to read them right to the chip and that would be through having water bonds coming down to your detectors so it goes to PCB and you're reading the information from the detector which is reading the information from your chip but also you can be driving your laser there's also an FDA on there so you you're a processed signal and you want to either transmit it or if you're receiving a signal molecule and that's going through your FAA so that's your now you get your photonics package so your pic isn't doesn't just go by itself into some sort prototype it needs an assembly around it to enable it and once
[11:10] assembly around it to enable it and once you've got that then you're able to plug.
[11:13] you've got that then you're able to plug it in whether it's from your into your prototype into your product on your workbench but you know that'll work every time.
[11:19] so just to kind of cover again those key aspects of what you're thinking about when you're paying together in a photonics package.
[11:29] the considerations here are you want to think about your optics so are you using fiber to get the light in and out of the chip.
[11:35] are you using a laser to directly onto the chip are you using detectors what kind of electronics is there.
[11:43] do you when do you use wire bones when would you use flip chip so these are constraints that we'll be talking about in future webinars as well.
[11:48] and give me a detail on when you do use each one and how you look at look at that in thermal implications.
[11:56] like we said you need a tech is it passive cooling and some of the mechanical applications there as well.
[12:02] so what you how does it look like what materials are you using do you need it to be also automatically sealed it's not for naught but yeah let's focus first on the optical side.
[12:13] Let's focus first on the optical side, start off there. So Francisco, can you start off there?
[12:16] So Francisco, can you maybe tell us a bit more about how I get my light?
[12:19] Maybe tell us a bit more about how I get my light, my light.
[12:19] All of the children, yeah, let's say that.
[12:21] All of the children, yeah, let's say that it's not just shining light, but it's it's not just shining light, but it's more, let's say understanding that you need to shine properly, okay, light into your big the photonic integrated circuits.
[12:25] It's not just shining light, but it's more, let's say understanding that you need to shine properly, okay, light into your big the photonic integrated circuits.
[12:28] More, let's say understanding that you need to shine properly, okay, light into your big the photonic integrated circuits.
[12:31] Need to shine properly, okay, light into your big the photonic integrated circuits as you said is like your processor.
[12:33] Your big the photonic integrated circuits as you said is like your processor, so you use it to solve problems.
[12:35] Circuits as you said is like your processor, so you use it to solve problems and this means that you need processor, so you use it to solve problems and this means that you need not just to shine light on something but you need to couple properly the light.
[12:39] Processor, so you use it to solve problems and this means that you need not just to shine light on something but you need to couple properly the light.
[12:42] Problems and this means that you need not just to shine light on something but you need to couple properly the light.
[12:47] Not just to shine light on something but you need to couple properly the light which means that for example you have a light pulse with many electromagnetic parameters.
[12:50] You need to couple properly the light which means that for example you have a light pulse with many electromagnetic parameters and you want to take care of all those parameters.
[12:52] Which means that for example you have a light pulse with many electromagnetic parameters and you want to take care of all those parameters.
[12:56] Light pulse with many electromagnetic parameters and you want to take care of all those parameters.
[12:58] Parameters and you want to take care of all those parameters.
[13:00] All those parameters that are important for you because you are putting some real important information in that specific, okay, parameter.
[13:03] That are important for you because you are putting some real important information in that specific, okay, parameter.
[13:06] Are putting some real important information in that specific, okay, parameter.
[13:09] Information in that specific, okay, parameter, so in this case, what we want to start doing is to offer training.
[13:12] Parameter, so in this case, what we want to start doing is to offer training.
[13:16] to start doing is to offer training programs which means that we are taking programs.
[13:19] which means that we are taking care of for example let's talk about as you said light coupling schemes so it's not just to put something on top of something else.
[13:25] so in this case for example light coupling schemes can be let's use a fiber the fiber can be the vertical fiber is the easiest way to cap a light into a system and let's say that we want to use the grating coupler okay.
[13:43] because we want to have a fixed phase so the grating coupler can help us in taking care of the face okay but the prom is that vertical fiber it's easy but from the mechanical point of view is not good so we can switch for example to the plane or example fiber that is better but the prom is that the beam shape is a little bit different and what happen if as you said before we are using a drone we can't have a long wire always connected to the drone so we need
[14:19] always connected to the drone so we need for example light sources and detectors.
[14:22] for example light sources and detectors hybrid li integrated on our deacon and.
[14:26] hybrid li integrated on our deacon and it means for example that we can resort.
[14:29] it means for example that we can resort to the so called micro optical bench so.
[14:32] to the so called micro optical bench so you will use lenses and Prisma in order.
[14:35] you will use lenses and Prisma in order to collect and bend the light and shine.
[14:37] to collect and bend the light and shine the light on top of the grating coupler.
[14:39] the light on top of the grating coupler but this process must be done properly.
[14:42] but this process must be done properly and again for example the beam profile.
[14:46] and again for example the beam profile is changing let's see for example in.
[14:49] is changing let's see for example in this case the mode field diameter if I.
[14:51] this case the mode field diameter if I ever an original fiber or a vertical.
[14:54] fiber or a vertical fiber I have a mode field diameter that.
[14:57] fiber I have a mode field diameter that is of the order of ten point four.
[14:58] is of the order of ten point four microns and it's okay for the grating.
[15:00] microns and it's okay for the grating catalyst but if I look at the motor.
[15:03] catalyst but if I look at the motor diameter that comes out of a laser it's.
[15:08] diameter that comes out of a laser it's too small for microns so the question is.
[15:10] too small for microns so the question is how can I use properly the photonic.
[15:13] how can I use properly the photonic packaging rules procedures the knowledge.
[15:17] packaging rules procedures the knowledge that I can acquire from studying all.
[15:20] that I can acquire from studying all these packaging rules and procedures in.
[15:23] these packaging rules and procedures in order to manage is not just manipulate.
[15:26] order to manage is not just manipulate is the fact that you really want to.
[15:28] is the fact that you really want to manage the light in this case if you.
[15:31] manage the light in this case if you properly let's say tune your micro.
[15:35] properly let's say tune your micro optical bench you can you can see on the.
[15:37] optical bench you can you can see on the right obtained again about fill diameter.
[15:40] right obtained again about fill diameter that is around 10 microns and this means.
[15:43] that is around 10 microns and this means that you are again able to couple in the.
[15:46] that you are again able to couple in the best way your light into your grating.
[15:49] best way your light into your grating coupler so you can use your picker to.
[15:52] coupler so you can use your picker to solve your problem right because it's.
[15:55] solve your problem right because it's not just light is exactly the life that.
[15:57] not just light is exactly the life that you need so in this case we want to.
[16:03] you need so in this case we want to change a little bit approach the point.
[16:05] change a little bit approach the point of view so in from devices to prototypes.
[16:08] of view so in from devices to prototypes there is not only just one however which.
[16:13] there is not only just one however which means that we are improving the.
[16:15] means that we are improving the materials we are improving the schemes.
[16:17] materials we are improving the schemes the techniques but we want also to.
[16:20] the techniques but we want also to improve the skills of the people working.
[16:24] improve the skills of the people working in photonics we want the people to be in photonics.
[16:27] we want the people to be always more and more trained which means always more and more trained.
[16:31] which means that they can solve more general problems.
[16:33] so if you see that you need something with a different thermal properties a material with a different thermal properties.
[16:38] what you can do is you can look for that so you can change the material and you know that is working.
[16:47] why because you know that you have to take care of the thermal but in addition density strain everything that can then affect the final result in your package which means reliabilities.
[16:59] which means it's working properly which means that you are getting out from the peak exactly what you want.
[17:07] what you think so our idea is let's say help the education and training world to move a little bit more forward going to the let's say small and
[17:29] forward going to the let's say small and medium enterprise direction so it's medium enterprise direction so it's something like we want to help the something like we want to help the people to have knowledge that can be people to have knowledge that can be immediately can be immediately useful in immediately can be immediately useful in the real world you know highs exactly we the real world you know highs exactly we want people to be able to put their want people to be able to put their hands and fingers in order to solve hands and fingers in order to solve problems not just gluing stuff okay you problems not just gluing stuff okay you know so in this case the first idea is know so in this case the first idea is let's start working at the academia let's start working at the academia level so let's start to bridge the gap level so let's start to bridge the gap between the academia and the small and between the academia and the small and medium enterprises so let's help the medium enterprises so let's help the students to learn practical things that students to learn practical things that are useful when they immediately after are useful when they immediately after that they get to degree they jump into that they get to degree they jump into the world of working in small and medium the world of working in small and medium enterprises and we can't forget the
[18:32] enterprises and we can't forget the people that are already working he's.
[18:36] people that are already working he's already missing exactly so in this case.
[18:38] already missing exactly so in this case we want.
[18:40] we want in addition let's say take care of them.
[18:43] in addition let's say take care of them which means that we want to start.
[18:46] which means that we want to start providing them specific trainings in.
[18:49] providing them specific trainings in order to give them all the support that.
[18:52] order to give them all the support that they need which means that you have to.
[18:54] they need which means that you have to take care of the time require that so.
[18:58] take care of the time require that so small in terms of time super focus.
[19:02] small in terms of time super focus trainings to three days and then the.
[19:05] trainings to three days and then the people can come back to work but with.
[19:07] people can come back to work but with improve skills so they can see.
[19:10] improve skills so they can see immediately the effects it yes this is.
[19:15] immediately the effects it yes this is the idea so we want to take care of both.
[19:19] the idea so we want to take care of both the realities people that are studying.
[19:22] the realities people that are studying and people that are already working and.
[19:25] and people that are already working and we want to give support.
[19:27] we want to give support 360 degrees which means that we want to.
[19:30] 360 degrees which means that we want to give them the support from the more.
[19:32] give them the support from the more let's say theoretical point of view.
[19:34] let's say theoretical point of view modeling or optimization or why not.
[19:38] modeling or optimization or why not testing how can I properly analyze the data.
[19:42] data am I sure that I'm measuring exactly what I think that I am measuring.
[19:46] yes we can provide them all the skills that are necessary to be sure that they are really effective every day in their job place.
[19:54] so in these regards we have in mind mainly let's say three different types of activities.
[20:02] the first one has I said our training courses on hot topics one two three days on specific topics.
[20:11] and the first should start in April next year April 2020.
[20:15] then the second activity is a one-week summer school ok July 2020.
[20:22] so you see something longer so it can be a different type of let's say like a place where you can meet the people that are already working for.
[20:34] people that are already working for example in academia or the people that
[20:36] example in academia or the people that are already working in small and medium
[20:38] are already working in small and medium enterprises we want to create like a
[20:41] enterprises we want to create like a point where the people can meet talk and
[20:44] point where the people can meet talk and understand each other helping each other
[20:46] understand each other helping each other to grow ok and then obviously their
[20:50] to grow ok and then obviously their webinar series and you introduce them to
[20:52] webinar series and you introduce them to the people so here so yeah I'll kind of
[20:56] the people so here so yeah I'll kind of touch on the point of the webinars here
[20:58] touch on the point of the webinars here that's very interesting so you're in
[20:59] that's very interesting so you're in terms of training and upskilling
[21:01] terms of training and upskilling people's what people and so you're
[21:04] people's what people and so you're saying there'll be some training courses
[21:05] saying there'll be some training courses next year the summer school and then
[21:09] next year the summer school and then we'll do some webinars as well series
[21:11] we'll do some webinars as well series where we go into detail or more detail
[21:14] where we go into detail or more detail about the key things in photonics
[21:17] about the key things in photonics stories packaging would also packaging
[21:19] stories packaging would also packaging itself advanced packaging system
[21:20] itself advanced packaging system integration all that good stuff so yeah
[21:23] integration all that good stuff so yeah like I was saying at the beginning of
[21:25] like I was saying at the beginning of this presentation and this is a stepping
[21:30] this presentation and this is a stepping into this world so it's an introductory
[21:32] into this world so it's an introductory webinar just to give you a feel of what
[21:35] webinar just to give you a feel of what your
[21:36] your get Percy next year so in 2020 so we're
[21:41] get Percy next year so in 2020 so we're expected to have here now the plan is
[21:43] expected to have here now the plan is every two months to have a weapon
[21:45] every two months to have a weapon webinar series and a webinar session in
[21:49] webinar series and a webinar session in the series to look at things like
[21:53] the series to look at things like Francesco mentioned here the design of
[21:55] Francesco mentioned here the design of the photonics package what aspects do
[21:57] the photonics package what aspects do you have to think of in detail take case
[22:00] you have to think of in detail take case studies when should you use wire bonding
[22:03] studies when should you use wire bonding when should you use flip chip which
[22:06] when should you use flip chip which coupling scheme should be should you be
[22:07] coupling scheme should be should you be using your technology looking at things
[22:11] using your technology looking at things of best practices for thermal management
[22:12] of best practices for thermal management will be also kind of interviewing some
[22:15] will be also kind of interviewing some of the technology leaders looking at
[22:17] of the technology leaders looking at equipment so there's there's quite a lot
[22:20] equipment so there's there's quite a lot of exciting stuff there going on for the
[22:21] of exciting stuff there going on for the next few webinars that are coming up in
[22:23] next few webinars that are coming up in 2020 why I would say is the best way to
[22:27] 2020 why I would say is the best way to stay connected and to know about what
[22:30] stay connected and to know about what we'll be presenting is to follow us on
[22:33] we'll be presenting is to follow us on your practice and on LinkedIn so follow
[22:35] your practice and on LinkedIn so follow your practice on LinkedIn and you'll be
[22:38] your practice on LinkedIn and you'll be able to hear what's coming next and to
[22:40] able to hear what's coming next and to know about the webinars you'll also be
[22:42] know about the webinars you'll also be able to kind of pay your suggestions of
[22:43] able to kind of pay your suggestions of what you would like to hear about as
[22:45] what you would like to hear about as well
[22:45] well so these are a few of the ideas that
[22:47] so these are a few of the ideas that were work currently working on to bring
[22:50] were work currently working on to bring to you in February and then can I kick
[22:53] to you in February and then can I kick that off in 2020 but yeah so it's kind
[22:58] that off in 2020 but yeah so it's kind of a Q&A session now so if you email
[23:01] of a Q&A session now so if you email your questions through to your practice
[23:02] your questions through to your practice that gateway to Tyndale that ie we can
[23:06] that gateway to Tyndale that ie we can then try to answer some of your
[23:07] then try to answer some of your questions but yeah so that's quite an
[23:10] questions but yeah so that's quite an interesting talk there about your
[23:12] interesting talk there about your training sessions so what kind of hot
[23:18] training sessions so what kind of hot topics have you got in mind
[23:19] topics have you got in mind but for sure he's quite an interesting
[23:22] but for sure he's quite an interesting topic in let's say see for example the
[23:27] topic in let's say see for example the coupling scheme sir is the example that
[23:30] coupling scheme sir is the example that I showed you before yes mainly because
[23:32] I showed you before yes mainly because it's the it's it's exactly the point
[23:38] it's the it's it's exactly the point where you are shining the light in ER
[23:41] where you are shining the light in ER and what happen is that you are
[23:45] and what happen is that you are interfacing the external world with your
[23:48] interfacing the external world with your peak so you have to pay attention and
[23:53] peak so you have to pay attention and not only in terms as I said of coupling
[23:56] not only in terms as I said of coupling efficiency which means the power that I
[23:58] efficiency which means the power that I am maybe losing but also the fact
[24:01] am maybe losing but also the fact because different coupling scheme sir
[24:03] because different coupling scheme sir can give you the solution to different
[24:06] can give you the solution to different problems and obviously the design of the
[24:11] problems and obviously the design of the cheaper is quite different so if you
[24:14] cheaper is quite different so if you consider rating couplers for example is
[24:16] consider rating couplers for example is different with respect to working with a
[24:18] different with respect to working with a CH coupling
[24:19] CH coupling much coupling for example is great for
[24:22] much coupling for example is great for hot plac connections and can be used for
[24:28] hot plac connections and can be used for example if you need to get direct access
[24:32] example if you need to get direct access to your picker but you do not have for
[24:34] to your picker but you do not have for example constraints in terms of face or
[24:40] example constraints in terms of face or for example in terms of conservation of
[24:46] for example in terms of conservation of some letter magnetic parameters while
[24:49] some letter magnetic parameters while the grating catalepsy is a more complex
[24:53] the grating catalepsy is a more complex scattering object you need to pay
[24:55] scattering object you need to pay attention to many other features
[24:57] attention to many other features obviously for example the wedding
[24:59] obviously for example the wedding coupler is good if you want to use it in
[25:02] coupler is good if you want to use it in addition it as a filter so you can alter
[25:05] addition it as a filter so you can alter the light so if you have a broadband
[25:08] the light so if you have a broadband source with a shape that is not for
[25:11] source with a shape that is not for example exactly what you need I don't
[25:12] example exactly what you need I don't know I'm imagine a Gaussian shape you
[25:15] know I'm imagine a Gaussian shape you can use the grating coupler to filter
[25:18] can use the grating coupler to filter the light and change the shape so it can
[25:22] the light and change the shape so it can be for example good if you need a
[25:23] be for example good if you need a perfectly Gaussian beam inside your
[25:27] perfectly Gaussian beam inside your waveguide right another question coming
[25:32] waveguide right another question coming in here and it's about the summer school
[25:36] in here and it's about the summer school what's happening in summer school then
[25:38] what's happening in summer school then well okay
[25:39] well okay in summer school the main idea is we
[25:42] in summer school the main idea is we want to create a place where people come
[25:47] want to create a place where people come from different let's say
[25:51] from different let's say I know Noah's Mali medium enterprises or
[25:56] I know Noah's Mali medium enterprises or for example PhD students and can stay
[26:00] for example PhD students and can stay together talk together and I'm thinking
[26:03] together talk together and I'm thinking in particular I think that we should
[26:06] in particular I think that we should really start to create a link between
[26:08] really start to create a link between academia and enterprises so what is
[26:13] academia and enterprises so what is important for example is that people
[26:15] important for example is that people that are working in enterprises start
[26:17] that are working in enterprises start talking to academia telling to the
[26:20] talking to academia telling to the academia what they need okay because it
[26:24] academia what they need okay because it seems that these are two separate words
[26:27] seems that these are two separate words thank you very much
[26:28] thank you very much and so I'm seeing here some comments
[26:30] and so I'm seeing here some comments from people that some people are
[26:32] from people that some people are imagined to see the view the webinar
[26:34] imagined to see the view the webinar fine others are having problems I see
[26:37] fine others are having problems I see some people are able to view see and
[26:40] some people are able to view see and hear the webinar fine others can't hear
[26:42] hear the webinar fine others can't hear it very well and some others the link is
[26:46] it very well and some others the link is not working for them so there's a range
[26:48] not working for them so there's a range here of technical issues for various
[26:51] here of technical issues for various people what I'll do is I will make this
[26:53] people what I'll do is I will make this available for you so that you're able to
[26:56] available for you so that you're able to download it later on until later on and
[26:58] download it later on until later on and maybe that's the better way to do that
[27:00] maybe that's the better way to do that at the moment so I'm not entirely sure
[27:03] at the moment so I'm not entirely sure what's happening there and technique the
[27:05] what's happening there and technique the technical problem because some people
[27:07] technical problem because some people are viewing it and they're sending
[27:09] are viewing it and they're sending through some questions here
[27:10] through some questions here others can't quite so sorry about that
[27:14] others can't quite so sorry about that but hopefully we'll have that teething
[27:15] but hopefully we'll have that teething problem out of the way for the next
[27:16] problem out of the way for the next webinar thank you very much for tuning
[27:18] webinar thank you very much for tuning in and like I say we'll make this
[27:22] in and like I say we'll make this webinar available for you to download
[27:24] webinar available for you to download and watch at your ease also if you have
[27:26] and watch at your ease also if you have a question follow-up questions later on
[27:28] a question follow-up questions later on because of the technical problem please
[27:30] because of the technical problem please feel free to drop us a line at your
[27:32] feel free to drop us a line at your practice gateway at Tyndall tonight
[27:34] practice gateway at Tyndall tonight thank you very much
