基于平面波展开法,设计三层一维光子晶体横磁场模结构,改变三层介质厚度和介质折射率的大小,应用MATLAB语言进行仿真计算,在一维光子晶体三层介质厚度值为0.4、0.05μm和0.05μm,折射率为1、3N和12N时形成一维光子晶体带隙宽度最宽为0.2694Hz。研究结论为一维光子晶体器件的设计提供理论依据。

Based on the plane wave expansion method,the three layer in one-dimensional photonic crystals with transverse magnetic field mode structure was designed,the three dielectric layer thickness and refractive index of medium were changed,MATLAB language was used to simulate and calculate of one-dimensional photonic crystal.When the three dielectric layer thickness values of one-dimensional photonic crystal were 0.4,0.05μm and0.05 μm,the refractive index of 1,3N and 12N,formation of one-dimensional photonic crystal band gap width was 0.2694Hz.The conclusion provides a theoretical basis for design of one-dimensional photonic crystal devices.
