Free-Space Laser Communications XXXIII.
As satellite constellations continue to expand and capacity demands grow, free-space optical (FSO) communication offers a complementary alternative to RF systems for low-Earth-orbit satellite communication networks. FSO systems can support higher lin

For low-Earth-orbit (LEO) satellite communication networks, free space optical (FSO) communication offers high data capacity and security without the spectrum limitations of more conventional RF approaches. However, receive signal power in FSO-LEO li

Free-space optical communication (FSO) enables high-bandwidth data links that are difficult to detect, intercept, and jam. In this paper we provide an overview of a small form factor FSO prototype intended for UAVs called OCELOT (Optical Communicatio

In free space optical communication, photodetectors serve not only as communications receivers but as position sensitive detectors (PSD) for pointing, tracking, and stabilization. Typically, two separate detectors are utilized to perform these tasks
