Abstract
We experimentally utilize a multi-plane light convertor (MPLC) for simultaneous orbital-angular-momentum (OAM) mode demultiplexing and turbulence-induced crosstalk mitigation. Results show up to 15-dB reduction of crosstalk in a two-mode 200-Gbit/s OAM-multiplexed link.

The crosstalk matrix and measured bit error rates (BERs) performance with turbulence (realization 1) are shown in Fig. 4(b1-b4). As shown in Fig. 4(b1-b2), for the case with turbulence and without using turbulence-induced crosstalk mitigation, the crosstalk is 13.25dB worse compared with that for the case without turbulence. After applying turbulence-induced crosstalk mitigation, the crosstalk for channel 1(ℓ = 0) and channel 2 (ℓ = +1) is improved by 11.26dB and 6.42dB as shown in Fig. 4(b3). As shown in Fig.4(b4), without using turbulence-induced crosstalk mitigation, channel 1(ℓ = 0) cannot achieve below 3.8e-3 FEC limit and channel 2 (ℓ = +1) has ~6dB power penalty at the 3.8e-3 FEC limit in BER performance. Using turbulence-induced crosstalk mitigation, there are ~0.2dB and ~2dB power penalty for channel 1 and channel 2, respectively.
