应用平面波展开法数值模拟了不同结构二维光子晶体TE模带隙特性,数值模拟得到正方形、正三边形和正六边形圆柱光子晶体结构的TE模带隙特性,比较得到正三边形圆柱结构光子晶体能够形成较宽TE模带隙结构。改变正方形圆柱光子晶体结构形成正方形椭圆柱结构和长方形圆柱结构光子晶体,比较得到长方形圆柱结构光子晶体形成带隙宽度较宽。研究就论为制作TE模滤波器件提供理论参考。
The TE mode bandgap characteristics of two-dimensional photonic crystals with different structures were numerically simulated by using the plane wave expansion method. The TE mode bandgap characteristics of the tetragonal, quadrilateral and regular hexagonal cylindrical photonic crystal structures were numerically simulated. The crystal can form a wider TE mode bandgap structure. Changing the square cylinder photonic crystal structure to form a square elliptic cylinder structure and a rectangular cylinder structure photonic crystal, the rectangular cylinder structure photonic crystal is formed to form a wider band gap. Research on the theory for the production of TE mode filter device provides a theoretical reference.
