摘要
具有切践包络的线性啁啾光纤光栅是用于色散补偿的重要无源器件。通过切趾的方法可以减少啁啾光纤光栅内的时延振荡 ,同时减小反射谱中的旁瓣。用数值方法分析了不同切趾包络函数对光栅特性的影响 ,得到了色散补偿最佳包络函数及其参数 ,给出了最佳包络的普遍特征。
The apodized linear chirped fiber grating is an important passive device for dispersion compensation.With the chirped fiber grating modulation strength or coupling coefficient varied or apodized,both the sidelobes in the grating reflectivity and the group delay oscillations of the grating can be reduced.Numercal analysis is made of the impact of different apodizion functions on the fiber grating performance,Leading to an optimum profile with its parameters for dispersion compensation and generalized characteristics of optimum profiles.
