Abstract: An optical phased array (OPA) may be included in a light detection and ranging (LiDAR) system and may be configured to perform beam steering. The OPA may include a cascading structure of splitters configured to enable a branch operation to be performed M times. Each splitter may split an input optical signal in a ratio of 1:1 and output the split input optical signal. The OPA may include a plurality of sets of first phase shifters (PSs), each set of first PSs located exclusively on one output end of a separate splitter, each set of first PSs including a particular quantity of first PSs based on a branch position at which the separate splitter is located. The OPA may be included in a LiDAR system that is further included in a vehicle that is configured to enable navigation of the vehicle, including autonomous navigation, through an environment.

Abstract: An optical transmitter includes photonic integrated circuits configured to respectively output optical transmission signals in different wavelength ranges. A photonic integrated circuit may include emitters configured to emit beams having different wavelengths; drivers configured to respectively provide power to the emitters, and a wavelength division multiplexer configured to transmit the beams emitted by the emitters. A photonic integrated circuit may include a switch device that controls the drivers, and light detectors configured to detect intensities of the beams emitted from the emitters. The switch device may selectively operate at least one driver of the plurality of drivers based on information associated with intensities of the beams. The switch device may selectively operate a driver connected to an emitter, based on a determination that an intensity of a beam emitted by another emitter is less than a threshold intensity value.
