Defect Modes of One - dimensional Photonic Crystals with Gradual Refractive Index Layer
Pages: 308-310
Year: Issue:  3
Journal: Laser & Infrared

Keyword:  光子晶体准周期结构缺陷模传输矩阵;
Abstract: 利用传输矩阵方法,研究了单折射率层缓变准周期结构一维光子晶体存在不同缺陷时的缺陷模.结果表明,当该准周期结构中存在缺陷时,引入了缺陷模,且缺陷模与缺陷层的位置和结构参数相关.缺陷层不同,缺陷模的位置及共振透射峰也不同.随着缺陷层光学厚度的增大,缺陷模波长向长波方向移动.
