SOLID-STATE LIGHT DETECTION AND RANGING (LIDAR) SYSTEM WITH REAL-TIME SELF-CALIBRATION

Abstract(summary):

A method and system for a coupler that receives power from a power source, and a waveguide connected to the coupler at a first end of the waveguide. A splitter is connected to a second end of the waveguide to receive the power traveling through the waveguide, and the splitter divides the power between a plurality of outputs creating divided power. A global phase shifter is connected to a first output of the plurality of outputs of the splitter, and the global phase shifter receives the divided power. An on-chip splitter is connected to the global phase shifter and further divides the divided power into sub-divided power. An on-chip phase shifter is connected to the on-chip splitter. An OPA is connected to the on-chip splitter. A phase monitor array is connected to the OPA, and a phase controller is connected to the phase monitor array.
