Packing antennas tightly on a silicon photonic chip without the catastrophic interference that typically ruins solid-state LiDAR signals

"LiDAR sensor needs wide field of view, placing many tiny antennas close together, achieve high-resolution 3D map, but crosstalk jumbling light beam/ spacing farther apart creates ghost beam copies confusing direction... overcome varying corrugations for unique propagation coefficients on each so they ignore each other... coupling from nearly 100% to 1%... LiDAR solid-state chip integrated into vehicle skin/ tiny robot (was spinning bucket on car roof)... scalable CMOS manufacturing, level 5 vehicles"
