摘要
在本文中 ,通过引入主模和独立模光栅的概念 ,对梯度多模光纤光栅进行了数值模拟 ,计算了反射率谱线图 ,并就介电常数微拢、光栅长度以及工作波长等参数的变化对光栅反射率谱图的影响进行了详细讨论。
In this paper, by making use of concepts of principal mode and independent mode grating, We simulate numerically the graded index multimode fiber grating and have achieved its reflected spectrum. Then the influences of the changes of parameters, such as the dielectric perturbation, grating length, and working wavelength on the grating reflected spectrum are discussed. The theorical spectrum is compared with experimental′s and this indicates that both of them are same basically.
