全光波长转换器是密集波分复用系统中的关键光电子器件,也是混合WDM/OTDM光网络实用化的关键部分。从脉冲传输方程和载流子密度方程出发,详细分析了相向工作方式下交叉增益调制型波长转换器转换后光的消光比和啁啾特性。在分段动态模型中考虑了剩余端面反射和自发辐射噪声的影响,模拟结果为交叉增益调制型波长转换器的性能优化提供理论依据。
All-optical wavelength converter is a key optoelectronic device in Dense Wavelength Division Multiplexing (WDM) systems and a key part of the practical use of hybrid WDM / OTDM optical networks. Based on the pulse transfer equation and carrier density equation, the extinction ratio and chirp characteristics of the converted light of cross-gain modulated wavelength converter are analyzed in detail. The effects of residual surface reflection and spontaneous emission noise are considered in the piecewise dynamic model. The simulation results provide a theoretical basis for the performance optimization of the cross-gain modulated wavelength converter.
