WebHere, we demonstrate automatic turbulence mitigation in a 2-Gbit/s quadrature-phase-shift-keying (QPSK) coherent FSO link using degenerate four-wave-mixing (DFWM)-based phase conjugation and fiber-coupled data modulation. Specifically, we counter-propagate a Gaussian probe from the receiver (Rx) to the transmitter (Tx) through turbulence. WebMay 25, 2024 · An optical setup for generating a phase-conjugate wave from a phase-conjugate mirror by four-wave mixing is shown in Fig. 1. The phase-conjugate mirror is assumed that it responds much faster than the typical fluctuations of chaotic of QD lasers (small value of τ ).
WebWe deploy kernel-based time-series prediction to suppress the phase noise induced by small deviations from ideal pump counter-phasing in a dual-pump optical phase conjugation system. We show experimentally 1.5-dB SNR improvement for 16-QAM signals at 4° pump-phase mismatch.
