Experimental Mitigation of Atmospheric Turbulence Effect using Pre-Channel Combining Phase Patterns for Uni- and Bi-Directional Free-Space Optical Links with two 100-Gbit/s OAM-Multiplexed Channels

摘要

We experimentally demonstrate the mitigation of atmospheric turbulence effects using pre-channel combining phase patterns in both uni- and bi-directional free-space 200-Gbit/s orbital angular momentum multiplexed optical links. The inter-channel crosstalk is reduced by up to 18-dB.
