摘要
设计了一种新颖的60km色散补偿8信道50GHz信道间隔的啁啾光纤Bragg光栅(CFBG)梳状滤波器。采用基于LP算法的IS光纤光栅设计技术,设计出CFBG的折射率调制函数和啁啾分布。根据设计得出的耦合系数分布,采用传输矩阵法分析所设计CFBG的反射谱、时延曲线和群时延抖动。结果表明,所设计的CFBG不仅满足了设计指标要求,性能优良,而且在已知的制作技术条件下可以实现。
A novel chirped fiber Bragg grating (CFBG) comb filter for eight-channel 50 GHz DWDM-channel separations and 60 km dispersion compensation was proposed. The index modulating function and chirp parameter distribution of the CFBG were synthesized by layer-peeling (LP) inverse scattering (IS) technique. According to the coupling coefficient calculated for the synthesized grating, reflection spectrum, group delay and group delay ripper were analyzed based on the method of transformation matrix. The results show that the CFBGs not only satisfy all requirements but also could be fabricated with existing techniques.
