Abstract: A light detection and ranging (LIDAR) sensor system includes a transmitter, one or more scanning optics, an optical module, and a receiver. The transmitter is configured to output a beam having a linear polarization. The optical module is configured to provide the beam to the one or more scanning optics. The one or more scanning optics are configured to output the beam received from the optical module. The receiver is spaced from the transmitter and receiver configured to receive a return beam from reflection of the beam by an object.

Abstract: A light detection and ranging (LIDAR) system for a vehicle includes a transmitter, a receiver, one or more scanning optics, and a circulator. The transmitter is configured to output a transmit beam. The receiver includes a first receive grating coupler and a second receive grating coupler. The circulator is configured to receive the transmit beam and provide the transmit beam to the one or more scanning optics, receive a return beam from reflection of the transmit beam by an object, split the return beam into at least a first component and a second component, and direct the first component to the first receive grating coupler and the second component to the second receive grating coupler.
