摘要: 建立了输入信号光偏振方向任意情况下的半导体光放大器(SOA)中垂直双抽运四波混频(FWM)效应的完整宽带理论模型.以基于SOA的垂直双抽运FWM型全光波长转换器为例,通过数值模拟的方法,理论研究了输入信号光与两抽运光功率、两抽运光与信号光之间的波长失谐量和输入信号光偏振方向等工作参数对SOA的垂直双抽运FWM效应及基于SOA的垂直双抽运FWM型波长转换器特性的影响.Abstract: A comprehensive broad-band model of orthogonal dual-pump four-wave mixing (FWM) in semiconductor optical amplifier (SOA) is presented in the case of the polarization state of the input signal being arbitrary. By performing numerical simulation and taking the allptical wavelength conversion based on orthogonal dual-pump FWM in an SOA for example, the effects of the input light powers, frequency detuning and polarization state of the input signal on the orthogonal dual-pump FWM and the performances of wavelength conversion are theoretically investigated.
