Adaptive optics based simultaneous turbulence compensation of multiple orbital angular momentum beams


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.
