1. An optical tracking module comprising:
an optical phased array (OPA) including:
a plurality of array elements, and
a plurality of phase shifters;
an analog drive configured to adjust the plurality of phase shifters;
an integrated photodetector configured to receive light from the OPA; and
one or more processors configured to:
extract signal information of an incoming beam via the OPA, and
control an outgoing beam using the analog drive based on the signal information; and
wherein the OPA, the analog drive, the integrated photodetector and the one or more processors are in an integrated circuit.
