Optical and Quantum Communications

We research and develop a wide range of space, airborne, and terrestrial communication systems. These systems include hardware for a terminal that is used in a near-Earth wideband relay laser communication system and prototypes of a beam director that will be integrated in a laser communication system. Our team has created the most sensitive high-data-rate laser communications links ever developed. We have also begun new research into extending the range and utility of undersea communication transceivers.
