摘　　要：本文提出了新颖的与偏振无关全光 2× 2光纤光开关结构 ,采用自由空间光互连模块 ,能够实现 2× 2与偏振无关的双向光纤光开关直通和交换功能。以此为基础 ,提出了新的全光 4× 4光纤光开关的光学实现方法。该光开关具有光学元件少、结构紧凑。A novel configuration of 2×2 all optical polarization independent bidirectional fiber optical switch is presented.Operation is independent of input signals of polarization of the optical beams.the straight and the exchange functions of 2×2 optical switch are implemented based on free space optical interconnection.Furthermore,a new optical implementation method of 4×4 all optical fiber optical switch is presented.This new kind of configuration of the optical switch grants the features of less optical components,high compactness and easiness to optical assembly.
