Backside emitting silicon photonic beam steering module for LIDAR application
Backside emitting silicon photonic beam steering module for LIDAR application
We present a silicon photonic beam steering device based upon an 8 x 8 grating coupler focal plane array fed by a MZI switching tree. Transmission of the light from the grating couplers is made through the back side of the chip using topside mirrors.
