title: 1.14 Tb/s DP-QPSK WDM polarization-diverse optical phase conjugation.
abstract: Optical phase conjugation (OPC) of a polarization-multiplexed comb of 10x114Gb/s DP-QPSK signals has been demonstrated for the first time, occupying a spectral bandwidth of >1 THz (~9 nm). The nonlinear element employed for the OPC was highly nonlinear fiber (HNLF) optimized for the suppression of stimulated Brillouin scattering (SBS) and configured in a bi-directional loop offering polarization diversity. Pump power (each way about the loop) and input signal power to the OPC subsystem were optimized at 29.7 dBm and + 3 dBm respectively producing a Q(2) penalty of ≤ 0.9 dB over all conjugate wavelengths, polarizations and output OSNR (up to 20 dB).
