Abstract: A free-space optical communication system includes an optical phased array (OPA) photonic integrated chip (114), a transceiver photonic integrated chip (112), and one or more processors (104). The OPA chip includes a plurality of array elements (120) and a plurality of phase shifters (121). The transceiver chip includes one or more transmitter components (116) and one or more receiver components (118). The one or more processors are configured to transmit a first signal via the OPA chip and the transceiver chip (402), and receive a second signal via the OPA chip and the transceiver chip (410).

Abstract: Aspects of the disclosure relate to an optical phased array (OPA) architecture for a device capable of transmitting and receiving both optical communications signals and light detection and ranging (LIDAR) signals. The OPA architecture may involve the use of a single OPA chip with a plurality of photonic integrated circuits (PIC). In this regard, the transmitters and receivers (or transceivers) of the OPA architecture may include switches. The transceiver switch may enable changing between transmitting and receiving optical communications signals and LIDAR signals.

Abstract: An optical phased array (OPA) photonic integrated chip (114) includes a plurality of array elements (120), a plurality of phase shifters (121), a plurality of combiners (230-234), and an edge coupler (236) configured to couple to a single mode waveguide. The plurality of phase shifters includes a layer of phase shifters that has a phase shifter connected to each array element in the plurality of array elements. The plurality of combiners is configured to connect the plurality of phase shifters to the edge coupler. The plurality of combiners includes a first combiner that has a first output that is connected to a second combiner or the edge coupler, and a second output of the first combiner is connected to a photodetector (240). An in-phase light portion at the first combiner is output through the first output, and an out-of-phase light portion at the first combiner is output through the second output.
