摘　　要：从描述F-P型半导体光放大器(FPSOA)中光子与载流子相互作用的行波速率方程出发,利用小信号分析法得到了光腔内部前、后向光场的微扰量的微分方程组,并利用其分析了FPSOA的频率响应特性。计算结果表明:FPSOA具有高通的频率响应特性。所得结论与已有文献报道的实验结果符合较好。Starting from the travelling rate equations describing the interactions between carriers and photons inside the Fabry Perot semiconductor optical amplifiers（FPSOAs）, a set of differential equations in terms of the perturbations of the forward and backward optical fields in the cavity are obtained via small signal analysis. Based on these equations, the frequency response characteristics of FPSOAs are investigated. The results show that FPSOAs possess high--pass frequency response characteristics. The conclusion of this paper agrees with the experimental results of previous literatures.
