Abstract
Aspects of the disclosure provide a system including a first communications terminal. The first communications terminal may include an optical phased array (OPA) including a plurality of phase shifters configured to receive an optical communications beam from a second communications terminal. The first communications terminal may also include one or more processors configured to determine a link axis for communication with the second communications terminal based on the received optical communications beam, identify a compensatory wavefront curvature for mitigating cross-coupling, and generate a wavefront of an outgoing optical communications beam using the plurality of phase shifters based on the determined link axis and the compensatory wavefront curvature.
