摘要
应用平面波展开法(PMW)计算了圆形立方晶格、正方形立方晶格及正六边形立方晶格三种不同结构的二维空气柱光子晶体带隙结构。结果表明,空气柱光子晶体存在对应TE、TM模的完全禁带,并且圆形空气柱光子晶体存在完全带隙。比较而言,圆形空气柱立方晶格的TE模禁带与完全禁带最宽,最宽禁带宽度分别为0.137(ωa/2πc)与0.018(ωa/2πc),正方形空气立方晶格的TM模禁带最宽,最宽禁带宽度为0.119(ωa/2πc)。
Three different structures of two-dimensional photonic crystal band gap air column structure which were the circular cubic lattice and square cubic lattice and hexagonal cubic lattice were calculated by the plane wave expansion method（ PMW）.The results show that air column photonic crystal of TE and TM modes exist completely forbidden band and circular air column photonic crystal exists entirely band gap.The TE forbidden band gap and completely forbidden band gap of circular air column are the widest,and the wide band gap width are 0.137（ ωa /2πc） and 0.018（ ωa /2πc） respectively; the TM forbidden band gap of square air cubic lattice is the widest which is 0.119（ ωa /2πc）.
