摘要
本文理论地研究了啁啾光纤光栅色散补偿变迹耦合函数，将两个耦合模方程推导为一个Ｒｉｃａｔｉ微分方程，然后通过Ｒｕｎｇｅ－Ｋｕｔａ法求解在不同耦合函数下啁啾光纤光栅的反射、色散和群时延，系统地讨论和比较了两种耦合函数下的啁啾光纤光栅补偿性能。
In this paper,we theoretically studied on the apodized function of chirped fiber gratings and deduced two couplingmode equations to a single Riccati differential equation.Solving this equation by the Runge Kutta method,We obtained the reflectivity,dispersion and time delay of chirped fiber grating.On the other hand,we discussed and compared the effect under the circumstances of two kinds of coupling functions.
