Mitigation of Nonlinear Impairments on QPSK Data in Phase-Sensitive Amplified Links

Paper in proceeding, 2013

We investigate the mitigation of nonlinear impairments via phase-sensitive amplification. We show in simulation and experiment that this effect can be optimized through engineering link dispersion. A phase-sensitive amplified link is measured to reduce nonlinear penalties by over 3dB compared to a phase-insensitive amplified link.
