变迹对啁啾光纤光栅色散补偿性能的影响

Influence of Apodization on Dispersion Compensation Property of Chirped Fiber Grating

利用传输矩阵法对啁啾光纤光栅的光学特性进行了数值求解,同时对啁啾光纤光栅进行了变迹处理,使用两种常用的变迹函数获得了较理想的光学特性,在此基础上构造了一种新的变迹函数,通过仿真结果表明,与常用的变迹函数所得到的光学特性相比,具有更宽的反射谱,更平稳的色散曲线,时延特性的线性度更好,使得啁啾光纤光栅作为色散补偿器的色散补偿性能更好。

The optical properties of chirped fiber grating gets numerical solution based on the transfer matrix,and gets the apodized processing.The ideal optical properties are achieved by using the two common apodization function,and a new apodization function is formulated.The simulation results show that chirped fiber grating based on the apodized processing has much wider reflection spectrum,smooth dispersion curve,better linearity of the delay characteristics,so that the chirped fiber grating achieves better performance of the dispersion compensation as the dispersion compensator.
