Abstract
Coherent free-space optical (FSO) communications systems offer both an opportunity for significantly increased data rates and improved security compared to conventional radio frequency (RF) systems. A key challenge in implementing FSO systems is the characterization and mitigation of atmospheric turbulence present along the optical channel. In this work, we present experiments demonstrating coherent free-space optical communications over a two-pass 800 m link with data rates on the order of gigabits per second (Gbit/s). The link consists of a single telescope and retroreflector. At the start/end point of the monostatic link we have built an optical transceiver capable of coherent communications. We present here design considerations and results from transmission in moderate turbulence.
