Abstract
We propose a PSA scheme employing bi-directional signal-conjugate generations and then dual-conjugate-pump FWM for phase regeneration of QPSK/8PSK and potentially 16PSK. We show effective reductions on phase noise deviation by 5.2 and 8.5 degrees for 25-Gbaud/s 8PSK and QPSK and verify its scalability at 50-Gbaud/s.
