Optical bistable device based on fiber Michelson Interferometer

利用光纤迈克尔逊干涉仪构造了一种新型电光混合频域光学双稳态器件。该结构的光学双稳器件具有多种双稳运行方式;加在光纤Fabry-Perot滤波器上的偏置电压、输入光强以及反馈电压增益,这3个参量调制其中一个同时保持其他两个不变都可以实现光学双稳运行,实验数据与理论分析一致。该结构光学双稳态器件可以应用于光开关、波长转换,波长调谐激光器以及光纤传感技术等许多领域。

A novel hybrid optoeiectronic bistable device in frequency-domain was constituted by using fiber Miehelson Interferometer. Optical bistable operations were achieved through adjusting any one among the bias voltage on tunable fiber Fabry-Perot filter, the intensity of the input light and the gain of the feedback circuit, and keeping the other two constant, Experimental results are well conformed to theoretical calculation. It could be used in many fields, such as the studies on optical switching, optical wavelength conversion, wavelength-tuning of fiber laser, and fiber-optic sensing technology.
