【摘要】：针对偏振复用相位调制信号的全光波长变换特性问题,基于半导体光放大器中四波混频效应,建立了对偏振复用正交相移键控信号的全光波长变换理论模型.根据理论分析,建立了仿真系统,仿真结果表明:泵浦光与信号光之间的频率间隔、偏振复用信号中的一个信号与一号泵浦光的偏振夹角对系统转换效率和信号质量有影响;波长转换过程中交叉相位调制产生的相位噪音会对信号质量有影响,且当泵浦光功率较大、泵浦光功率远大于信号光功率时,交叉相位调制效应的影响较小,仿真结果与理论分析一致.本文研究方法和相关结论对其它偏振复用信号基于半导体光放大器四波混频效应的波长变换研究有一定的参考价值.
[Abstract]:Based on the four-wave mixing effect in semiconductor optical amplifiers, a theoretical model of all-optical wavelength transformation for polarization multiplexed quadrature phase-shift keying signals is established. According to the theoretical analysis, the simulation system is established. The simulation results show that the frequency interval between the pump light and the signal, and the polarization angle between one signal of the polarization multiplexing signal and the No. 1 pump light have an effect on the conversion efficiency and signal quality of the system. The phase noise generated by cross-phase modulation during wavelength conversion will have an effect on the signal quality. When the pump power is large and the pump power is much larger than the signal optical power, the effect of cross-phase modulation is less. The simulation results are consistent with the theoretical analysis. The research methods and related conclusions in this paper have some reference value for the study of wavelength conversion of other polarization-multiplexed signals based on the four-wave mixing effect of semiconductor optical amplifiers.
