Published purpose

Inter-satellite optical communication requires accurate pointing and tracking capabilities to ensure a reliable free-space link between satellites is established. In addition, correction of atmospheric fluctuations is necessary to allow for high-bandwidth connectivity between satellites and ground stations. Current existing systems with adaptive optics are large and fragile, potentially slow, with reliability issues that are unsuited for satellite-based systems. In this proposed research project, a solid-state integrated system compatible with CMOS technology will be exploited, without any mechanical moving parts. The proposed solution could be highly beneficial in terms of fabrication volume, cost, and robustness, especially for miniaturized satellites. The proposed research, if successful, could provide immediate benefit to established technologies, in the near term, e.g. LIDAR systems; and in the long term, will have direct impact to satellite free-space optical communications.
