"Shashua also will explain how Intel’s specialized silicon photonics fab is able to put active and passive laser elements on a silicon chip. “This is really game-changing,” Shashua said of the lidar SoC expected in 2025. “And we call this a photonic integrated circuit, PIC. It has 184 vertical lines, and then those vertical lines are moved through optics. Having fabs that are able to do that, that's very, very rare. So this gives Intel a significant advantage in building these lidars.”
Update: Intel has publishes the CES talk on Youtube.
It's more like a 1D optical phased array (OPA) to me (with edge emitting antennas). The 184 lines may either refer to the # of the antennas or the # of the line scan steps. Did you find the explicit mention of FMCW? I know Intel has been working on both OPA and FMCW.
ReplyDeleteIntel has just published the CES talk where FMCW is explicitly mentioned:

I've also added these slides to the post.
