摘要
本文利用耦合模方程对线性啾光纤光栅的反射谱进行了计算，并讨论了方程中各参数对计算结果的影响．
In this paper,a coupled mode equation was used to calculate the reflection spectrum of chirped fiber Bragg gratings with different parameter. It has been observed that the chirped gratings can be looked as a connection of series of period fiber gratings,and its FWHM has a close relation with chirp coefficient F (the bigger the F is,the broader the FWHM is),on the other hand,the reflectivity of the chirped grating will be enhanced with the increased grating length.
