Abstract

An intensity-based algorithm is employed to derive the correction phase pattern for a distorted probe orbital-angular-momentum (OAM) beam. This correction pattern is used to compensate the distortions of three multiplexed OAM beams, each carrying a 50-Gbaud QPSK signal. The crosstalk between channels is reduced by >5 dB with this approach.
