Dispersion characteristics of defect mode in 1-D square doped photonic crystal waveguide

摘要: 为了研究1维方形掺杂光子晶体波导中缺陷模的色散,采用特征矩阵的方法研究了1维方形掺杂光子晶体波导中TE波和TM波缺陷模的变化特征,得到了TE波和TM波的缺陷模随色散强度、色散厚度变化的结果。结果表明,色散强度和色散厚度都会对1维方形掺杂光子晶体波导中TE波和TM波的缺陷模产生明显的影响;利用TE波和TM波的缺陷模随色散强度、色散厚度的变化规律,可以有效地实现对1维方形掺杂光子晶体波导中TE波和TM波各传输模式的有效控制。

Abstract: In order to study the dispersion characteristics of 1-D square doped photonic crystal waveguide,the defect modes of TE wave and TM wave in 1-D square doped photonic crystal waveguide were studied based on the characteristic matrix.Response curves of the defect mode of TE wave and TM wave versus dispersion strength and dispersion thickness were obtained.Dispersion strength and dispersion thickness can produce apparent effect on the defect mode.The defect mode of TE wave and TM wave in 1-D square doped photonic crystal waveguide can be effectively controlled according to the dispersion characteristics of defect mode.
