10 Gbps coherent free-space optical communication without wavefront correction
Abstract
A novel method for receiving coherently encoded optical signals, without adaptive optics or other wavefront correction approaches, is demonstrated in atmosphere along with a fully-fade tolerant 10 Gbps modem. The receiver sensitivity using a DPSK signal is compared with OOK, and power penalties are evaluated. The experiment confirms the ability of the receiver to function without wavefront correction at high data rates with the ability to scale to higher-order modulation.
