We demonstrated a scheme to spectrally combine two high power, broad-linewidth single
beams using a steep edge filter as the combining element. 10.12 kW combined output …

Multi-aperture receiver with optical combining architecture is an effective approach to
overcome the turbulent atmosphere effect on the performance of the free-space optical …

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 …

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 …

We experimentally evaluated performance of a mode diversity receiver in severe fading
channels of emulated LEO-to-ground link. Digital combining of three modes using adaptive …

We discuss an optical ground terminal receiver architecture based on multi-aperture digital
coherent combining. Experimental results using four receivers demonstrate lossless …

In this day and age, free space optical (FSO) enable the deployment of a new category of
products that can transmit voice, data, and video at bandwidths up to 2.5 Gbps at distances …
