An optical aperture system is provided that includes a photonic integrated circuit. The photonic integrated circuit includes a plurality of apertures, a plurality of optical phase shifters coupled to respective apertures of the plurality of apertures, an optical splitter-combiner coupled to the plurality of optical phase shifters, an optical switch coupled to the optical splitter-combiner, a light source coupled to the optical switch, and a photodetector coupled to the optical switch. The optical aperture system further includes a controller configured to execute a first set of instructions to control the plurality of optical phase shifters and the light source in accordance with a first operating mode of a plurality of operating modes of the optical aperture system, and a processor configured to execute a second set of instructions to process an output of the photodetector in accordance with the first operating mode of the optical aperture system.

A planar waveguide laser crystal assembly includes an optical bench and a laser crystal mount mounted on the optical bench. The laser crystal mount includes an upper housing having an interior horizontal surface and an exterior horizontal, a lower housing coupled to the upper housing and having an interior horizontal surface and an exterior horizontal surface, and a cavity defined between the interior horizontal surfaces of the upper and lower housings. A laser crystal is mounted in the cavity of the laser crystal mount. Each of the exterior horizontal surfaces of the upper and lower housings is oriented parallel to a length of the laser crystal. The laser crystal assembly further includes a heat dissipating structure thermally coupled to at least one of the exterior horizontal surfaces of the upper and lower housings to dissipate heat transferred from the laser crystal mount.
