Abstract

We experimentally demonstrate 'automatic' turbulence mitigation of a self-coherent FSO MDM link with four 1-Gbaud QPSK channels using a transmitted pilot beam and PD array without power-splitting losses or detector-bandwidth sharing. Results show <3-dB turbulence-induced penalty, as compared to a >16-dB penalty for a conventional LO-based MDM system.
