摘要

基于半导体光放大器(SOA)中四波混频(FWM)的中链路光相位共轭(OPC)可用于补偿CO-OFDM长途系统中的非线性相位噪声(Gordon-Mollenauer效应)。对无色散补偿的40Gb/s CO-OFDM系统进行了仿真，通过OPC可使Q因子提高>6 dB。

Compensating Gordon-Mollenauer phase noise by midlink optical phase conjugation for long-haul 40Gb/s CO-OFDM systems

Midlink optical phase conjugation (OPC) based on four wave mixing (FWM) in semiconductor optical amplifier (SOA) can be used to compensate for the nonlinearity phase noise, Gordon-Mollenauer effect, in CO-OFDM long-haul systems. Simulation of 40Gb/s CO-OFDM systems without optical dispersion compensation is presented and the Q factor can be increased by >6 dB through OPC.
