理论研究并模拟仿真了在半导体光放大器(SOA)中的基于平行双抽运结构的偏振复用十六进制正交幅度调制-正交频分复用(16QAM-OFDM)信号的全光波长变换(AOWC)。理论推导及仿真结果表明偏振复用16QAMOFDM信号可以经过全光波长变换实现偏振不敏感信号无串扰直接接收，并对影响系统转换效率的因素，如频率间隔、SOA 注入电流、信号光功率及信号光入射角等进行了分析，同时分析结果验证了理论推导的正确性。

The all-optical wavelength conversion (AOWC) based on parallel dual-pump for polarization multiplexing 16 quadrature amplitude modulation arthogonal frequency division multiplexing (16QAM-OFDM) signal in semiconductor optical amplifier (SOA) is theoretically analyzed and simulated. The theoretical analysis and simulation results show that the polarization multiplexing 16QAM-OFDM signal can be received without crosstalk after AOWC by direct-detection, besides that several conditions which affect the AOWC conversion efficiency in this system are analyzed, such as frequency spacing of parallel pumps, SOA injection current, average power and the azimuth of optical signal. This simulation results also validate the correctness of theoretical analysis at the same time.
