1. A system comprising:
one or more light sources;
a plurality of waveguides;
at least one outcoupler comprising an outcoupler;
a phase control network;
a detector;
a first reflector; and
a system interface including a launch region and a detection region, wherein:
the plurality of waveguides are configured to route light generated by the one or more light sources to the at least one outcoupler;
the phase control network is configured to control a relative phase of a portion of the light routed by at least one of the plurality of waveguides;
the plurality of waveguides terminate at a free propagation region;
the first reflector is configured to redirect the light from the plurality of waveguides to the outcoupler;
the outcoupler is configured to redirect the light to form a launch beam that exits the system via the launch region; and
the detector is positioned to detect a portion of the launch beam that is returned to the system via the detection region.
