Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure varable distances. For self driving lidar is used to detect objetcs around the car and their movements, if any. Going from the cpu to the laser and back at lightspeed requires alot of photonics hardware, that POET just so happens to have.

To get into the automotive supply chain, low cost and reliability are king, again POET is in the right place at the right time.

Global auto sales are ~65 million per year, so the potential market is significant.
