Mitigating cross-coupling in optical communications system

A method comprising for generating an outgoing communications beam at a first communications terminal, the method comprising:

• determining, by one or more processors, a link axis for communication with a second communications terminal based on a received optical communications beam;
• identifying, by the one or more processors, a compensatory wavefront curvature for mitigating cross-coupling;
• and
• generating, by the one or more processors, a wavefront of an outgoing optical communications beam using a plurality of phase shifters of an optical phased array (OPA) architecture based on the determined link axis and the compensatory wavefront curvature.

A non-transitory machine-readable medium on which instructions are stored, the instructions, when executed by one or more processors, cause the one or more processors to perform a method of generating an outgoing communications beam at a first communications terminal, the method comprising:

• determining a link axis for communication with a second communications terminal based on a received optical communications beam;
• identifying a compensatory wavefront curvature for mitigating cross-coupling;
• and
• generating a wavefront of an outgoing optical communications beam using a plurality of phase shifters of an optical phased array (OPA) architecture based on the determined link axis and the compensatory wavefront curvature.
