We propose an adaptive optics compensation scheme to simultaneously compensate multiple orbital angular momentum (OAM) beams propagating through atmospheric turbulence. A Gaussian beam on one polarization is used to probe the turbulence-induced wavefront distortions and derive the correction pattern for compensating the OAM beams on the orthogonal polarization. By using this scheme, we experimentally demonstrate simultaneous compensation of multiple OAM beams, each carrying a 100  Gbit/s data…

Atmospheric turbulence effects on the performance of a free space optical link employing orbital angular momentum multiplexing.
TLDR
The experimental results show that the power of the transmitted OAM mode will tend to spread uniformly onto the neighboring mode in medium-to-strong turbulence, resulting in severe crosstalk at the receiver, and the power penalty is found to exceed 10 dB in a weak- to-medium turbulence condition.
Influence of atmospheric turbulence on states of light carrying orbital angular momentum.
TLDR
This work experimentally studied the degradation of mode purity for light beams carrying orbital angular momentum (OAM) propagating through simulated atmospheric turbulence, showing that turbulence uniformly degrades the purity of all the modes within this range, irrespective of mode number.

TLDR
A multichannel free-space optical (FSO) communication system based on orbital angular momentum (OAM)-carrying beams is studied and it is found that turbulence induces attenuation and crosstalk among channels.

TLDR
The transfer of information encoded as orbital angular momentum states of a light beam is demonstrated, which is resistant to eavesdropping and gives an experimental insight into the effects of aperturing and misalignment of the beam on the OAM measurement and demonstrates the uncertainty relationship for OAM.
