| 摘 要： | 本文用传输矩阵法分析了各种变迹与线性啁啾Bragg光纤光栅的响应特性,构造了各种变迹函数,进行了比较.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.找到了最佳变迹函数和量佳啁啾系数.特例中的数值分析表明,补偿100km光纤色散带宽为1nm的最佳光栅长度是140mm,最佳啁啾系数为0.048nm/cm.

| Abstract: | 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.In specific instance,it is shown by a numerical analysis that the optimal length and chirp parameter of a grating is 140mm and 0.048nm/cm respectively to compensate the dispersion induced by an 100km fiber with 1nm bandwidth. |
