摘要
对各种变迹与线性啁啾Bragg光纤光栅的色散特性作了数值分析 ,构造了各种变迹函数 ,进行了比较 .研究了变迹函数、啁啾系数、折射率变化量以及光栅长度对色散补偿带宽。
The time delay characteristics of non_uniform optical fiber gratings with different types of apodising and chirping structure are analyzed using numerical method. For understanding and designing fiber gratings we defined apodization profile functions and calculated numerically. The influence of apodization profile functions,the variation of the induced index and chirp parameter on the dispersion compensation,the time delay characteristics and the bandwidth has been studied.
