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: A beam steering optical phased array (OPA) may include an optical signal distributor including a plurality of output terminals configured to divide and output input optical signals and phase shifters arranged at the plurality of output terminals and configured to receive the divided optical signals and shift phases thereof to generate phase-shifted optical signals. The beam steering OPA may include antennas configured to receive the phase-shifted optical signals and an optical signal interferometer. The optical signal interferometer may include first input waveguide regions connected to a limited selection of the antennas and extending in a first direction, a multi-mode waveguide region connected to the first input waveguide regions, and a first output waveguide region connected to the multi-mode waveguide region and extending in the first direction. The beam OPA may enable errors due to process dispersion to be effectively corrected, and thus, the beam steering OPA may have enhanced reliability.
