基于传输矩阵法,设计多层一维光子晶体,改变层数和入射角度,应用MATLAB语言进行仿真计算,得到入射角度为0.2rad时,8、16、24层和32层一维光子晶体在[9.77—23.39]THz频范围内存在一个低传输率的传输禁带,只是在两侧的低频和高频部分Fabry-Perot峰变得越来越紧密。改变入射角度为0.1rad、0.2rad和0.3rad时,在低频带范围Fabry-Perot峰变化不大,传输禁带依次增大,高频带部分逐渐压缩。研究结论为一维光子晶体传输器件的设计提供参考。
Based on the transfer matrix method, multi-layer one-dimensional photonic crystals were designed, the number of layers and the incident angle were changed, and the simulation calculation was carried out by using MATLAB language. When the incident angle was 0.2 rad, the 8,16,24- and 32- 9.77-23.39] There is a transmission band gap with low transmission rate in the THz frequency range, except that the Fabry-Perot peaks become more and more dense at the low and high frequencies on both sides. When the incident angle is 0.1rad, 0.2rad and 0.3rad, the Fabry-Perot peak changes little in the low frequency band, the transmission band gap increases and the high frequency band partially compresses. The conclusion of the research provides reference for the design of one-dimensional photonic crystal transmission device.
