| 摘 要： | 从耦合波理论出发，利用传输矩阵分析了啁啾超结构光纤光栅，得到了其反射谱的解析式，数值计算结果表明：超结构光纤光栅的光栅总长度、折射率调制深度、占空比、取样周期和啁啾系数等参数都会影响反射谱的峰值和带宽。为超结构光纤光栅的设计提供了理论依据。

| Abstract: | Chirped super-structured fiber grating is studied by transfer matrix on the basis of the coherence theory. The reflective spectrum is obtained. The numerical calculation results show that the maximum of reflective spectrum and bandwidth of super-structured fiber grating depends on its total length, modulating the amplitude of the refractive index, duty cycle T, sampling period P and chirped coefficient C. So certain theoretical references in the design of it can be gained. |
