Abstract: An integrated chip packaging for a LIDAR sensor mounted to a vehicle includes a laser assembly configured to output a beam, an optical amplifier array chip configured to amplify a beam, and a transceiver chip coupled to the laser assembly and the optical amplifier array chip. The transceiver chip may be configured to emit the beam with reference to a first surface of the transceiver chip through an optical window and receive a reflected beam from a target through the optical window. The integrated chip packaging for the LIDAR sensor defines the configuration of optical components for providing a path for the optical signal to travel in and out of the LIDAR sensor and dissipating the heat generated by the optical components for improved performance.

Abstract: A LIDAR transceiver includes a source input, coherent cells, and an optical switch. The optical switch is configured to switchably couple the source input to the coherent cells. At least one of the coherent cells includes an input port, an optical antenna, and a splitter. The input port is coupled to the optical switch and the splitter is coupled between the input port and the optical antenna. The splitter is configured to split a received portion of a laser signal into a local oscillator signal and a transmit signal, where the transmit signal is emitted through the optical antenna. A reflection of the transmit signal is received through the optical antenna as a reflected signal, where the splitter is further configured to output a return signal that is a portion of the reflected signal.
