From an ASIC SOC technical writer's perspective and as the producer of the Semiconductor Subject Matter Expert Database, your presentation is excellent. Ideal reference material for writing about silicon photonics. It was a good idea to introduce the photonic building blocks, fiber optics packaging fundamentals and associated technical issues. As you say, many in the ASIC domain are new to photonics. Lightmatter's approach, that is replace the 2D arrays of multiply-accumulate units used in present day GPU based natural machine language AI Processors with an optical equivalent, i.e. programmable Mach-Zehnder interferometer or photonic vector matrix multiplication units, doubles down on the benefits of near-zero latency photonic IO ports. I have been researching heterogeneous ASIC solutions with silicon photonic waveguide interconnect as an alternative to wire interconnect and as a way to get around silicon IO latency, power and delay obstacles. This has brought me to other photonic interconnection alternatives like microLEDs, MEMS mirrors, LiFi, nanowire LEDs, photodetector arrays, and lasers.

great presentation, very insightful and learned a lot, thanks
