摘要
构建了棋盘复式晶格介质环型光子晶体结构,采用平面波展开法对该结构的完全带隙宽度及结构参量进行了优化。研究结果表明,在优化参数下,完全带隙宽度的最大值为0.160,带隙率可达30.59%。该结构的大完全带隙具有很好的稳定性。
The structure of dielectric ring-shaped photonic crystals based on the checkerboard complex lattice is constructed. By the plane wave expansion method, the complete bandgap width of this structure and the structural parameters are optimized. The study results show that, under the optimal parameters, the maximum value of the complete bandgap width is 0. 160, and the bandgap ratio is 30.59%. The proposed structure has a good stability.
