Moin, ich hätte noch 3 Fragen zum Vortrag: 1. Wie weit unterscheiden sich die hier vorgestellte _Wake-Up Technik_ von _Target Wake Time (TWT),_ welche z.b. im IEEE 802.11ah (Wi-Fi HaLow) Standard steht? Bzw. kann man mit der hier vorgestellten Technik diese IEEE Norm erfüllen? 2. Bei 1:08:00 wird beide Rechnungen mit Primärzellen durchgeführt. Könnte man nicht eine Gegenrechnung mit Sekundärzellen, wie LiFePO4 26650er mit 1W PV Modul aufstellen, welche sich immer wieder aufladen kann, um diese weitere Möglichkeit zu beleuchten? 3. Hat die ESP32-Serie von Espressif, nicht viele hier genannten Eigenschaften von Haus aus, wie etwa der ESP32-C6er?

4:49 why did they not make the Silicon waveguide the same width as the fibet?

I lived in Germany and went to public German school from the age of kindergarten through third grade… I completely forgot how you can just take 17 words and stick them together and make one word in German, until I started reading the closed captions Great Vid! Thanks

At 5:39, I was expecting a sum of the field integrals in the dominator. Can you please explain why I am wrong? Thanks so much!

Hi Paul Tuhin, Please find here the feedback from Wojtek regarding your question: The easiest argumentation is the check of units: if there was a sum, instead of product, in denominator, the coupling efficiency would not be unitless. For more detailed mathematical treatment please search textbooks or internet for “mode overlap integral” or “projection of wave function onto eigenstates”. Note that the mentioned wave function represents the amplitude of electric field. For calculating the power coupling efficiency you need the integrals of the square of electric field.

Utilizing the optical interconnect technology created by LightMatter, it would be great inspiration to the computer industry if an entire glass based motherboard was created connecting all computer components, cpu, gpu, memory, etc. via optical waveguides

What if Cerebras, LightMatter, UltraRam, and AMD and Nvidia came together to build a fully integrated server using panel level packaging via optical interconnects. Imagine the speed and power efficiency of said system!!!

This are the kind of presentation that photonics field needs to approach society and make people understand how our lives may improve thanks to scientific innovations and the engagement of more and more people. From MEETOPTICS we are proud to be part of the photonics community and to help engineers and researchers in their search for optical lenses through our site. We celebrate every step forward and we hope new people join our community every day!

Dear @Namig Alasgarzade. The online workshop series has ended for the time being under the title »IZM Photonics: IN GLASS WE TRUST«. You can find all the other online seminars of the series on our youtube channel or on our website: www.izm.fraunhofer.de/en/news_events/trainings-and-workshops/online-sessions--izm-photonics-in-glass-we-trust.html. Stay tuned about our next online workshop series named: "»IZM PHOTONIK PACKAGING: IN OPTICAL INTERCONNECTS WE TRUST« with more interessting speakers and topics about the photonic interconnection technologies at Fraunhofer IZM.

Optical fiber coupling to photonics chip by Wojciech Lewoczko-Adamczyk at kzbin.info/www/bejne/qHnGl5ijqcuDaNU Suggest you use the whole screen for the graphs, equations, diagrams. It is too small to read easily and I do not need to see your face while you are looking at the screen. Such are called "screen videos", where you and the viewer are looking at the whole of something together. All your links are to generic pages, not to your work and these topics. The links are too vague and waste time tracking down this interesting topic. Some very nice methods, materials and components. But you are right that there is a mismatch in size and methods. My immediate impression from the mismatch would be to put an array of the chips on the whole face of the fiber, map the channel, and find optimal paths (primarily timings and correlations). If you have lots of fiber, use it. Don't make the fiber more expensive to fit one chip, just put lots of chips on existing infrastructure. It means more sensitive detectors in 2D arrays, but that is not too hard. But you can't hand if off to a graduate student. It becomes a statistical communications channel, not forcing small pieces to work together. Putting N^2 channels through an existing fiber is a fun project, and challenging enough to keep your interest. Just like disk drives and memory chips, you map the bad sectors, the bad and good channels. Some would call it "lucky imaging". It will work for copper as well.
