摘要
文章应用传输矩阵法对取样光纤布拉格光栅(SFBG)的反射谱进行了数值模拟,并分析了折射率调制幅度、占空比、取样周期和光栅长度等光栅参数对其反射谱的影响,在此基础上用切趾函数对其进行旁瓣干扰处理,得到了较为理想的8通道SFBG反射谱。
In this paper,we simulate the reflective spectrum of the Sampled Fiber Bragg Grating（SFBG） by using the transfer matrix method and analyze the effects of the index modulation amplitude,duty cycle,sampling period and the length of grating on the reflective spectrum.On this basis,we use apodization function to eliminate the sidelobe disturbance and obtain a better reflective spectrum of an 8-channel SFBG.
