摘　　要：利用光子转换理论的受激喇曼散射(SRS)耦合方程,结合双向多波长泵浦和光纤级联两种方法,提出了一种新型的具有平坦增益的宽带光纤喇曼放大器(FRA)。采用数值解法对100信道的波分复用(WDM)系统进行了仿真,得到了宽带增益平坦的功率输出,为光纤喇曼放大器(FRA)增益平坦化提供了一种新的实现方法。Anovel gain -flattened broadband Fiber Reman Amplifier （FRA）is presented by using the simulated Raman scattering（SRS）coupled equations with the photon transfer theory, and by combining with bidirectional multi-wavelength pumps and cascaded Fiber Raman Amplifier（FRA）.The 100-channel WDM system is simulated and it has been received output power with gain-flattened broadband. A new method for the gain flattening of FRA is provided.
