摘要
二维单斜点阵光子晶体在光学聚焦器件及光子晶体波导中有重要的应用价值,详细讨论了二维单斜点阵光子晶体的第一布里渊区及带隙计算,并与常规方法计算得出的二维正三角形晶格光子晶体的带隙结构进行了比较.最后讨论了临界条件下二维单斜点阵光子晶体的带隙结构,证明了本方法的有效性.
Two-dimensional （2D） monoclinic lattice photonic crystal has potential application for light focusing device and photonic crystal waveguides. In this article, the first Brillouin zone （BZ） and the method of calculating the photonic band gaps of two- dimensional monoclinic lattice photonic crystal are discussed. The photonic band gap （PBG） structure of triangular lattice photonic crystal calculated by the method described in this article agrees well with that from the conventional method. Furthermore, the calculated PBG structure of 2D monoclinic lattice in critical conditions are consistent with either hexagon or rectangle BZ, which shows that the method described here is valid.
