Since launch in May 2022, NASA's TeraByte Infrared Delivery (TBIRD) program has
successfully demonstrated 100-Gbps and 200-Gbps laser communication downlinks from a …

Delivery of large volumes of data from low-Earth orbit to ground is challenging due to the
short link durations associated with direct-to-Earth links. The short ranges that are typical for …

We investigated the performance of mode diversity reception of a polarization-division-
multiplexed (PDM) signal with few-mode-fiber (FMF) coupling for high-speed free-space …

The nanosatellite optical downlink experiment (NODE) implements a free-space optical
communications (lasercom) capability on a CubeSat platform that can support low earth orbit …

Direct‐to‐Earth transmissions with optical on/off‐keying are becoming the method of choice
to realize telemetry downlinks from low Earth orbit satellites at highest data‐rates. Here, we …

The next generation free-space optical communications infrastructure will need to support a
wide variety of space-to-ground links. As a result of the limited size, weight, and power on …

This letter considers availability maximized ground station (GS) selection for free-space
optical (FSO) satellite networks, which is a challenging problem in the area of optical …

Architecture of a 10 Gbauds link between new high complexity optical ground station
suitable for feeder link and a geo-stationary satellite is described. Such link is tested in …

Optical satellite links have gained increasing attention throughout the last years. Especially
for the application of optical satellite downlinks, DLR's Institute of Communications and …

Future Earth Observation satellite data downlinks via directed laser beams are a promising
