摘要
为了说明线性啁啾光纤光栅能成为色散补偿技术发展的重要方向,介绍了一种光纤光栅的耦合模理论模型,提出了用于色散补偿的自构变迹函数线性啁啾光纤光栅,并对线性啁啾光纤光栅与用于色散补偿的高斯变迹函数线性啁啾光纤光栅的反射谱及时延特性进行了数值仿真。仿真结果表明,自构变迹函数下的线性啁啾光纤光栅对光纤色散具有更好的补偿效果。
In order to demonstrate that linearly chirped fiber gratings can be an important development direction of dispersion compensation technology,a coupling mode theoretical model of fiber gratings is introduced in this paper,and a linear chirped fiber gratings with self-constructed apodized functions is proposed for dispersion compensation.The reflection spectrum and delay characteristics of linearly chirped fiber gratings with Gaussian apodized functionsused for dispersion compensation and self-constructed apodized functions are simulated numerically.The simulation result shows that the effect of linearly chirped fiber grating with self-constructed apodized functions is better for dispersion compensation.
