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.
