All-optical phase-preserving amplitude regeneration of 28-Gbaud RZ-DQPSK signals with a microcavity saturable absorber in a recirculating loop experiment

摘要

Microcavity Saturable absorber is used for phase-preserving amplitude regeneration of RZ-DQPSK signals. The regenerator is assessed in a 28 Gbaud recirculating loop showing system tolerance to nonlinear phase noise and distance improvement.
