Description: The Innovation: A monolithically grown device consisting of a solar cell integrated modulating retroreflector is proposed. This “DataCell” device allows for simultaneous electrical energy harvesting (photovoltaic effect) AND high-speed optical data communication (quantum-confined Stark effect) for free-space optical (FSO) links up to GHz rates in a single integrated device.

Benefits: Free Space Optical Cubesat Communication Planetary Landers – Lunar Surface Relays Secure Communication Satellite Orbit Determination Power Generation

Department of Defense: FSO for ground, UAS, underwater and space applications, directed energy applications Logistics Internet of Things Consumer Electronics
