Abstract
A LIDAR system, optical coupler for a LIDAR system and method of optical communication. The LIDAR system includes an optical coupler having a chip-side face in optical communication with a photonic chip and a scanner-side face in optical communication with a scanner, the optical coupler comprising a polarization rotator and a birefringent wedge. A first beam of light is transmitted from the first location toward a chip-side face of an optical coupler to direct the first beam of light, via the optical coupler, along an optical path at a scanner-side face of the optical coupler. A second beam of light is received along the optical path at the scanner-side face and directed the second beam of light toward a second location.
