Abstract
A free-space optical (FSO) communication system includes a transmitter including a modulated light source and transmit optics for emitting a modulated optical signal into a FS channel toward a receiver. A receiver is coupled to receive the modulated optical signal including receive optics coupled to a few-mode (FM) pre-amplifier that is coupled to a demodulator.
