Abstract: Aspects of the disclosure provide a method of adjusting a plurality of phase shifters of an OPA. The method may include identifying a plurality of subsets of phase shifters of the plurality of phase shifters based on an orthogonal set of functions; performing a plurality of dithers iteratively on the plurality of subsets of phase shifters of the plurality of phase shifters using the same frequency; determining a plurality of corrections based on a plurality of outputs of the OPA, each output resulting from each of the plurality of dithers; and adjusting the plurality of subsets of phase shifters of the plurality of phase shifters using the plurality of corrections, the adjustment resulting in at least one set of corrected phase shifter values.

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: Aspects of the disclosure provide a method of adjusting a plurality of phase shifters of an OPA. The method may include identifying, by one or more processors, one or more first subsets of phase shifters of the plurality of phase shifters based on an orthogonal set of functions; performing, by the one or more processors, one or more first dithers on the one or more first subsets of phase shifters of the plurality of phase shifters using one or more first frequencies of a predetermined set of frequencies; determining, by the one or more processors, one or more first corrections based on a first power output of the OPA resulting from the one or more first dithers; and adjusting, by the one or more processors, the one or more first subsets using the one or more first corrections, the adjustment resulting in a first set of corrected phase shifter values.
