提出并实验研究了采用压电陶瓷调制的光纤环形镜与光纤光栅结合的新型波长选择性光纤开关 ,获得了开关动态范围大于 16 d B、波长选择端口插入损耗小于 0 .5d B的实验结果。研究表明光纤环形镜干涉臂长的平衡是器件的关键。
A new type of wavelength-selective optical fiber switch combined with fiber ring mirror and piezoelectric fiber grating was proposed and experimentally obtained. The experimental results show that the switching dynamic range is greater than 16 dB and the insertion loss of wavelength selective port is less than 0.5d B. Research shows that the balance of fiber ring mirror interference arm length is the key to the device.
