全光非线性开关是全光3R再生的关键技术。在对一种全光开关[超快非线性干涉仪(UNI)]的传输函数进行分析后,得到了超快非线性干涉仪窗口的数学描述。在此基础上通过实验得到了40Gb/s的全光开关。并结合实验条件,具体分析了影响超快非线性干涉仪开关窗口的几个因素:增加半导体光放大器(SOA)的注入电流,增大控制脉冲的平均功率和调节连续光功率到最佳值,都能有效地改善输出窗口的形状和消光比,并对这种现象在理论上进行了初步分析。可以利用上述结论指导超快非线性干涉仪实验,从而使超快非线性干涉仪系统得到最大程度的优化。
All-optical non-linear switch is the key technology of all-optical 3R regeneration. After analyzing the transfer function of an all-optical switch [Ultrafast Nonlinear Interferometer (UNI)], the mathematical description of the ultrafast nonlinear interferometer window is obtained. On this basis, all-optical 40Gb / s switches are obtained through experiments. Combined with the experimental conditions, several factors affecting the switching window of the ultrafast nonlinear interferometer are analyzed in detail: increasing the injection current of the semiconductor optical amplifier (SOA), increasing the average power of the control pulse and adjusting the continuous optical power to the optimal value, Can effectively improve the shape of the output window and extinction ratio, and this phenomenon in theory conducted a preliminary analysis. The above conclusion can be used to guide the experiment of ultra-fast nonlinear interferometer, so that the ultrafast nonlinear interferometer system can be optimized to the maximum extent.
