摘　　要：提出了用级联方向耦合器组成光纤反射器的设想，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。All fiber reflectors using two stage directional couplers are proposed. The reflectivity and transmissivity of both optical field and intensity are derived. And the characteristics of such reflectors are analyzed and compared for each basic reflector configuration.
