摘　　要：根据陷波滤波器均衡法的原理,用光无源器件耦合器来修正掺铒光纤放大器增益谱线的不平坦,并探索出一种可以方便快捷地得到耦合器相关参数的方法.利用该方法可以对任何一个掺铒光纤放大器的增益谱进行优化设计,从而得到耦合器的相关参数,使得通过耦合器后的掺铒光纤放大器增益谱线的起伏小于给定阈值.Coupler was used to rectify EDFA's gain spectrum based on the principle of gain equalizing technology. A method was suggested to achieve the suitable parameters of the coupler. Any EDFA's gain spectrum can be designed by using the method presented and the parameters of coupler can be achieved conveniently. Connecting the coupler to the EDFA, the ripple of gain spectrum at different wavelengths becomes less than the limit value, i.e., the gain spectrum becomes flat.
