| 中文摘要 | 为了了解基于差分交叉相位调制的波长转换器(DXPM-WC)的工作机理并对提高其现有的性能,利用半导体光放大器(SOA)的动态模型对DXPM-WC的脉冲波形、消光比、信号光功率范围和啁啾进行了仿真分析。通过与传统的交叉相位调制波长转换器(XPM-WC)的性能比较,仿真结果表明:基于差分交叉相位调制的波长转换器的工作码率高于SOA的载流子动态响应速率,其输出信号可获得13dB以上的消光比和2GHz以下的频率啁啾。同时,提出一种扩大DXPM-WC输入信号功率动态范围的方案,以保证当输入信号功率偏移最佳值时,DXPM-WC输出的波长转换信号的消光比仍保持在13 dB以上。; The performance of the wavelength converter based on differential cross-phase-modulation(DXPM-WC) was improved by analyzing the system characteristics,including its pattern effect,extinction ratio and frequency chirp in simulations using a dynamic model of the semiconductor optical amplifier(SOA).Comparisons with the conventional wavelength converter based on cross-phase-modulation(XPM-WC) show that the DXPM-WC can operate at bit rates beyond the carrier response bandwidth in SOA,with the converted signal from the DXPM-WC having high extinction ratios(>13 dB) and low frequency chirp(<2 GHz).A method was also developed to broaden the dynamic power range of the DXPM-WC input signal,so that the output converted signal can maintain a high extinction ratio(>13 dB) when the input signal power is detuned from the optimum value. |
