Abstract

We experimentally demonstrate simultaneous turbulence mitigation and channel demultiplexing in a 200 Gbit/s orbital-angular-momentum (OAM) multiplexed link by adaptive wavefront shaping and diffusing (WSD) the light beams. Different realizations of two emulated turbulence strengths (the Fried parameter r₀ = 0.4, 1.0 mm) are mitigated. The experimental results show the following. (1) Crosstalk between OAM l = +1 and l = −1 modes can be reduced by >10.0 and >5.8 dB, respectively, under the weaker turbulence (r₀ = 1.0 mm); crosstalk is further improved by >17.7 and >19.4 dB, respectively, under most realizations in the stronger turbulence (r₀ = 0.4 mm). (2) The optical signal-to-noise ratio penalties for the bit error rate performance are measured to be ∼0.7 and ∼1.6 dB under weaker turbulence, while measured to be ∼3.2 and ∼1.8 dB under stronger turbulence for OAM l = +1 and l = −1 mode, respectively.
