Abstract

Performance of a nonlinear amplifying loop mirror and a fiber optical parametric amplifier in saturation used as phase-preserving amplitude limiters was investigated in a setup simulating a DPSK transmission system. The Q-factor improvement as well as the power penalty reduction have been compared under identical conditions. Both regenerators provide a similar Q-factor improvement, but the nonlinear amplifying loop mirror yields a better power penalty reduction.
