摘要
用传输矩阵法从理论上分析计算了相移光栅的反射谱特性。讨论了各光栅参量变化对反射光谱的影响规律。通过数值分析 ,得出结论 :采用合适的光栅参数可获得反射率高 ,通带宽及旁瓣干扰小的相移光栅。
Reflective spectrum of phase_shifted fiber Bragg grating was analized by a transfer matrix method.The effects of grating parameters on the phase_shifted grating specialities were observed.Through numerical analysis,we draw a conclusion that if we select suitable grating parameters, we can get optimistic Phase_shifted fiber Bragg gratings with high reflective peaks,broad bandwidths and low sidelobes.
