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、易于光学装配等特点
In this paper, a novel polarization-independent all-optical 2 × 2 optical fiber switch structure is proposed. The free-space optical interconnection module is used to realize the 2 × 2 polarization-independent bidirectional optical fiber switch-through and switch function. Based on this, a new optical realization method of all-optical 4 × 4 fiber optic switch is proposed. The optical switch with fewer optical components, compact structure, easy optical assembly and so on
