We experimentally demonstrate turbulence-resilient free-space optical (FSO) coherent
communications with multiple multiplexed data channels in different orthogonal domains …

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 …

Performance analysis is presented for a decode-and-forward protocol based mixed
radiofrequency (RF) and free-space optical (FSO) dual-hop transmission system with digital …

Coherent combination of laser beams from 37 fiber amplifiers in a tiled aperture
configuration has been achieved thanks to an innovative iterative process. The high …

Coherent digital combining technology using multiple small apertures has a lot of
advantages over doing so with a single large aperture, including the effective mitigation of …

In recent years, the coherent beam combining technique for laser transmission in
atmosphere has been widely investigated, while the study of this technique's application in …

Space-based VLBI imaging can dramatically improve state-of-the-art astronomical radio-
imaging resolution by enabling significantly longer baseline distances and eliminating …

This paper experimentally investigates the perform-ance of free-space optical (FSO)
