增益钳制半导体光放大器的静态特性分析

Static Character Analysis and Experiment of Gain-clamped SOA

采用增益钳制半导体光放大器 (GC SOA)的时域模型 ,计算并分析了GC SOA的静态特性。分析表明 ,在同样的注入电流下GC SOA较普通SOA的 3dB饱和输出功率有所提高 ,并且在GC SOA的增益饱和之前其增益一直稳定在阈值处。还用外腔反馈的方法构成GC SOA ,并对其静态特性进行实验研究。

Time-domain GC-SOA model is used to analysis the static character of GC-SOA. It is proved that the 3 dB-saturation output power of GC-SOA is higher than the conventional SOA, and its gain is much more stable than the conventional SOA before saturation. The external feedback GC-SOA is set up, and the experiments show the special characteristics of GC-SOA.
