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 Laser Communication and Atmospheric Propagation XXX.
For terrestrial free space optical (FSO) communication applications, large area photodetectors not only allow for more efficient power coupling but also ease the effects of atmospheric turbulence. When fabricated in array form, these devices have the

Photodetectors in free space optical communication systems perform two functions: reception of data communication signals and position sensing for pointing, tracking, and stabilization. Traditionally, the optical receive path in an FSO system is spli

Four different widely tunable polarization-stable lasers, each based on nonpolarization maintaining erbium-doped fiber are presented. We experimentally examine the effect of output coupling on laser performance, and compare the output power measureme
