Abstract
An adaptive optics compensation approach for an OAM multiplexed FSO communication system is described, in which a Gaussian beam is used to probe the turbulence-induced wavefront distortions and derive the correction pattern for compensating the OAM beams. Using this approach, we demonstrate simultaneous compensation of multiple OAM beams each carrying a 100-Gbit/s data channel through emulated atmospheric turbulence. The results indicate that the turbulence-induced crosstalk and power penalty could be efficiently mitigated by ˜12.5 dB and ˜11 dB respectively.
