Abstract
A LIDAR or other optical beamsteering apparatus includes an optical switch having a first port and a plurality of second ports. The switch is operated to establish an optical path between the first port and one of the second ports. The first port is connected to a light source or a light detector. Different second ports are connected to different surface/edge couplers. Each of the surface/edge couplers couples light from or to the apparatus in a different respective direction. The surface/edge couplers can be grating couplers. The direction of light coupling is configured due to the orientation of the surface/edge coupler and its grating period, where applicable. Surface/edge couplers can be arranged in a circular or concentric ring pattern. Grating couplers can be elongated.
