摘　　要：利用傅里叶变换的方法 ,对超结构光纤光栅的谱特性进行了分析 ,将其结论与耦合模理论的结果进行了比较和研究 ,在反射率较低时两者得到了很多一致的结论。经推导发现 ,取样光纤光栅的反射峰间隔Δλ不只和光栅周期 p有关 ,而且与取样率T 关系密切。The spectral property of super-structured fiber grating was analyzed with Fourier transposition. The conclusion was then compared with the results gotten form the deduction with coupled mode theory. The two outcomes were unified with each other in many aspects, when reflective ratio was low enough. Furthermore, it is found that the interval Δλ between two reflective peaks of sample fiber grating was related not only to the period p of grating, but also closely to sampling rate T. The result is proved by experiment.
