| 摘 要： | 以行波放大器速率方程为基础，采用传输矩阵方法，对行波放大器的增益饱和特性进行了理论研究，讨论了增益饱和特性对电流注入水平，腔面反射率的依赖关系，以及俄歇复合过程在行波放大器增益放大的作用，虽然俄歇复合过程可能提高饱和光强，但它会降低量子效率及非饱和增益，对器件的实际工作特性没有益处。

| Abstract: | Based on rate equations of carriers and photons, using transfering matrix method method, the gain saturation properties of semicoductor laser amplifier (SLA) are analysed theoretically. The dependences of SLA′s gain and gain saturation on the injected current density and facet reflectivity are discussed. Although the Auger process may increase saturation intensity, it decreases the internal quantum efficiency and unsaturated signal gain greatly, so it isn′t desired in SLA. |
