摘　　要：本文提出了用级联方向耦合器组成四端口全光纤反射器的设想，给出了其基本结构形式，推导了各种结构的光场量和强度的反射和传输系数，并对其特性进行了分析和比较．In this paper,four-port all-fiber reflectors using two - stage directional couplers were proposed,the reflectivity and transmissivity of both optical field and intensity were derived, respectively,for each basic reflector configuration,and the characteristics of such reflectors were analyzed and compared.
