| 摘 要： | 使用Ⅴ-Ⅰ传输矩阵法分析了相移量、相移点位置以及啁啾系数对啁啾相移光纤光栅透射谱特性的影响,并分析了在啁啾光纤光栅中同时引入多相移时生成的多陷波滤波器的波长间隔,发现其与以同样的位置引入单相移时陷波滤波器的波长偏离间隔基本一致。依据仿真分析结果,可以优化啁啾相移光栅相移数量、位置间隔、啁啾系数和相移量的参数选择,设计出实际需要的多波长滤波器。

| Abstract: | V-I transfer matrix method is used to analyze phase-shifting, phase-shifted point position and the in？fluence on phase-shifted fiber Bragg grating （FBG） transmission spectrum characteristic from chirped coefficient. The wavelength spacing of the multi-notch filter generated by inserting multiple phase shifts into the chirped FBG is analyzed. It is similar to the wavelength shifting spacing of the notch filter, which inserts single phase shifting at the same position. According to simulation results, chirped phase-shifted grating shifting number, position interval, chirped coefficient and phase-shifting can be chosen optimally to design the applicable multi-wavelength filter. |
