LIDAR PIXEL WITH ACTIVE POLARIZATION CONTROL

A light detection and ranging (LIDAR) pixel includes a splitter, a grating coupler, and a phase shifter. The grating coupler is configured to emit a transmit beam that is based on a combination of a first portion of light and a second portion of light received from a laser. One or more first interconnects and one or more second interconnects couple the splitter to the grating coupler. The phase shifter is coupled to the one or more first interconnects and configured to vary a phase of the first portion of the light relative to a phase of the second portion of the light.
