摘要
基于马赫—曾德尔(M—Z)干涉仪和光纤光栅Sagnac环,设计出高反射率和大反射带宽的光纤光栅梳状滤波器。模拟仿真了滤波器的输出特性。在工艺允许范围内,设计出反射带宽达5nm,反射率接近100%的梳状滤波器。所设计的梳状滤波器可以在光纤传感和通信领域中获得广泛的应用。
Based on Mach--Zehnder interferometer and the fiber Bragg grating Sagnac loops, a novel optical fiber comb-filter is designed which offers high reflectivity and big reverberation bandwidth. The output characteristics of the filter are simulated. Within the process allows, a comb-filter with reverberation bandwidth of up to 5 nm and refleetivity near 100% is designed, which can be widely applied in optical fiber sensors and optical fiber communications fields.
