非均匀光纤光栅响应特性的研究

Non Uniform Optical Fiber Grating Response

光纤光栅在未来光纤通信与光纤传感系统中将起关键性作用。本文进行了不同线型光栅变迹与啁啾等波导结构参数下的非均匀光纤光栅响应特性的数值计算，并通过对光栅响应不对称性的研究讨论，提出了光栅响应对称性的两个一般条件。

Optical fiber gratings will play very important roles in future′s optical fiber communication and sensing systems. The responses of non uniform optical fiber gratings with different types of apodising and chirping structure are numerically studied. Based on the general of non symmetric response of non uniform optical fiber grating, two conditions for symmetric response are provided.
