NASA’s first end-to-end optical relay system, Laser Communications Relay Demonstration (LCRD) uses the Optical Ground Station-1 (OGS1) at Table Mountain Facility, Wrightwood, CA, for high-rate optical communication with the flight terminals on a geo-synchronous satellite. The AO system at OGS1 has performed in weak to...

Some ground-based optical terminals used in optical uplinks employ adaptive optics (AO) to pre-correct the outgoing, data-carrying laser beams, which helps reduce scintillation and other, turbulence-induced signal im-pairments. The beacon photons can come from the satellite itself or from a natural guide star. After AO...

To address the urgent need for new satellite constellations for high-speed communication and high-precision orbit determination, this paper designs an intersatellite heterodyne coherent laser mixed-domain integrated communication and ranging system, achieving deep integration of communication and ranging functions. The...

The JPL Deep Space Optical Communications (DSOC) technology demonstration has validated a first of a kind system for long range free space optical communication. The ground laser transmitter (GLT) of DSOC system is located in the coudé room of the 1m telescope at Optical Communication Telescope Laboratory, Table Mounta...

The combination of modulating retro-reflector (MRR) architecture and coherent detection constitutes a highsensitivity, lowpower asymmetric link solution for underwater wireless optical communication (UWOC). Because the transmitter and receiver share the same optical source and the signal undergoes round-trip propagatio...

Photonic lanterns are investigated for use in extracting lowest order spatial mode beams from light aberrated after propagation through atmospheric turbulence. Both 1x7 and 1x19 photonic lanterns have been tested and in each case the lantern was at the focus of a 100mm aperture, f/2 lens. The angular throughput of thes...
