Nonlinear distortion is suppressed in Raman-assisted optical phase conjugation of CO-OFDM signals, resulting in improvement of 10 dB in optimized output power, 1.2 dB in Q factor, and 7 dB in input power dynamic range.
We demonstrate the use of Raman amplification to mitigate nonlinear distortion in optical phase conjugation (OPC) for a coherent optical orthogonal frequency-division multiplexing system. The OPC distortion is suppressed by lowering the input signal power. Meanwhile, the back-propagating Raman pump enhances the conversion efficiency, thus maintaining a comparable conjugated output signal power. The...
