摘　　要：提出了臂内含有光纤光栅的方向耦合器的一般模型，推导了任意端口输入时任何一端口的输出表达式。作为特例，研究了两类法布里－珀罗干涉谐振腔，发现它们之间存在一种交换等价关系。A general model for fiber directional coupler with fiber Bragg gratings in its arms is presented. The output expression of any arm is obtained when input is from an arm. As examples, two types of F P interferometer are analyzed. We find that an exchange equivalence relationship exists between them. For the first time we descrie the concepts of amplitude modulation caused by in fiber Bragg gratings in F P resonator.
