Silicon Photonics: The Next Silicon Revolution?

What other silicon photonics topics would you like to see?

"No Silicon can emit light..." That is not what my design did when I accidentally applied 20V to it instead of 3.3V.

Can’t believe I randomly decided to check Asianometry only to find out he had uploaded 8 seconds before. So much win!

You missed covering the only reason why you'd want to actually do photonics at the die level: photon based computation. You can already do basic logic operations using phase interference, but the really wild stuff starts happening when you start instantly resolving massively complex Fourier transforms by shining a coherent light through a filter. I knew a guy who worked at Lucent waaay back in the day, and I remember him talking about a project involving a fiber optic network switch that could route traffic without having to first move the data off the fiber and onto copper. A completely uninterrupted light beam. I wondered how that would even be possible over the years, then I read up on photonics - which is how you'd do it. Lookup the youtuber [Huygens Optics], specifically his video [Making Optical Logic Gates using Interference]

I developed optical ICs and simulators 27 years ago. Glad to see that the market has finally moved ahead to use the technology. Now the need has increased sufficiently to justify production development. Applications include LIDAR and high speed optical communications. The need will not be as high as other technologies but the volume will be enough to employ quite enough engineers.

Speed in optical fiber is the speed of light in glass or about 0.7 c. Now hollow core fiber which is new is close to 0.99

Wow, I learned a lot. Thank you for all the work, and for sharing. I did a PhD in theoretical solid state physics (superconductivity) in 1976 and yet even with that background I find your videos so cutting-edge educational and well presented, that when a new one pops up, everything else stops so that I can watch it.

Again, stunning presentation and deep insight into difficulties from a technical aspect as well as commercialization. With a lot of the tech websites seeming to be circling the drain, its great to see in-depth analysis is not dead. I fully expect you to reach 1M subs and more in the coming year or two if you can keep this up. I'd rather see 1 every 2 weeks if it would help to prevent burnout. Would be interesting sometime to see an episode on what you think is a potential new technology that is possible in the near term.

Dedicated AI hardware has shifted from CPU -> GPU -> FPGA -> Custom ASIC -> Analog based Custom ASIC. I think Photonics will be the next efficiency milestone. Analog AI hardware might be an idea for a video?

For those of you who are wondering what GSG and GSGSG stand for, it's Ground-Signal-Ground-(Signal-Ground). It refers to the layout of the electrical probes used to connect the high frequency instrumentation to the device.

Ah Jon! Another episode that's not just a home run, but knocks it clean out of the park! The realization that an optical gate can't be smaller than the wavelength of the light it operates on puts everything into perspective. I'm hoping for an episode on the research on room temperature super conductors and their implications for chip making!

As an Analog CMOS Designer, I am pretty sure that things you have mentioned in this video are being realized today, and it will be the key technology in some next decades.

Man, I've been wondering for years, maybe almost a decade, what ever happened to this space and you've really outdone yourself with this video. Thank you very much !

I am amazed by how you manage to break down such a complex topic into an easily understandable 15 min video

Sometimes I sit here and think to myself ..man he's feeding us all this information Imagine who feeds him information...like it's very impressive that he's able to get or find this information not to mention the detailed pics...has he done a Q and A? If not he should soon

For those interested in the inner workings of photonics, the youtube channel of The Royal Institution has a recent lecture about this (search for optical computers), which explains how it works excellently. The takeaway for me was that photonics can make clever use of the physics of light to do calculations that would be quite involved in traditional silicon, making it excellent for specific applications such as fourier transforms, edge detection of images, radar signal processing and neural networks, among others.

1:40 Don't forget about the index of refraction!

Slowly becoming my favourite channel on youtube. Been here since the beginning 👌

The stuff inside optical chips is kind of insane. So much simulation and math is used to refractivly bend light with tactically placed blocks of different refractivity in the nano scale. Just insanity

This is becoming one of my favorite channels. Fascinating stuff!
