摘要
该文对各种变迹与线性啁啾Bragg光纤光栅的响应特性进行了数值计算 .分析了变迹函数、啁啾系数、折射率变化量以及光栅长度对反射带宽、最大反射率的影响 .特例中给出了长度为 140mm ,啁啾系数为 0 .0 4 8nm/cm的各种变迹与线性啁啾Bragg光纤光栅的响应特性数值计算结果 .
The responses of non uniform optical fiber gratings with different types of apodising and chirping structure are analyzed using matrix method .For understanding and designing fiber gratings we defined apodization profile functions and calculated numerically. We found that the optimal apodization profile is the raised cosine shape.
