Abstract: A light detection and ranging (lidar) system for a vehicle may include a receiver layer, a transmitter layer coupled to the receiver layer through an adhesive layer in a first direction, and one or more optics. The transmitter layer may receive, at a first side of the transmitter layer, a transmit signal from a laser source, and transmit the transmit signal through the one or more optics. The receiver layer may receive, through the one or more optics, a return signal reflected by an object in an environment of the vehicle, and output the return signal at a first side of the receiver layer. The first side of the transmitter layer and the first side of the receiver layer may be apart from and parallel to each other in a second direction crossing the first direction.

Abstract: Manufacturing an integrated chip packaging for a LIDAR sensor mounted to a vehicle includes obtaining a metallic housing including a cutout on a side of the metallic housing, obtaining a ceramic radio frequency (RF) circuit board including a flange, coupling the flange of the ceramic RF circuit board to the cutout on the side of the metallic housing, applying a sealing material to an interface between the flange of the ceramic RF circuit board and the cutout on the side of the metallic housing, and locally heating the flange of the ceramic RF circuit board to bond the flange of the ceramic RF circuit board to the cutout on the side of the metallic housing thereby forming a seal at the interface.

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.
