Abstract: A photonic integrated circuit includes a photonic device. The photonic device includes an input region configured to receive an input signal including a plurality of multiplexed channels. The photonic device includes a metastructured dispersive region structured to partially demultiplex the input signal into an output signal and a throughput signal. The output signal includes a channel of the multiplexed channels. The throughput signal includes the remaining channels of the multiplexed channels. The photonic device includes an output region and a throughput region optically coupled with the metastructured dispersive region to receive the output signal and the throughput signal, respectively. The metastructured dispersive region includes a heterogeneous distribution of a first material and a second material that structures the metastructured dispersive region to partially demultiplex the input signal into the output signal and the throughput signal.

Abstract: An optical phased array (OPA) photonic integrated chip includes a plurality of array elements, a plurality of phase shifters, a plurality of combiners, and an edge coupler 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. 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.

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.
