摘要
利用电磁波在一维(1D)圆柱掺杂光子晶体中径向受限的条件,推导出电磁波在一维圆柱掺杂光子晶体中各个模式满足的关系式。利用特征矩阵法计算出TE波和TM波各模式的缺陷模的变化规律。得出了一些一维圆柱掺杂光子晶体缺陷模的新特征。TE波和TM波的缺陷模频率都随模式量子数的增加而增大,而随圆柱半径的增加而减小。TE波的缺陷模频率半峰全宽(FWHM)随模式量子数的增加而减小,但随圆柱半径的增加而增大。TM波的缺陷模频率半峰全宽的变化情况与TE波相反。
The condition of electromagnetic wave mode is obtained by restrictions condition of electromagnetic wave in the cylindrical one-dimensional（1D） doping photonic crystal.The defect modes of TE wave and TM wave are calculated by the characteristic matrix method.The new defect mode structures of cylindrical doping photonic crystal are obtained.The defect mode frequencies of TE wave and TM wave increase with increasing quantum number but decrease with increasing cylinder radius.The defect mode full-width at half-maximum（FWHM） of TE wave decreases with increasing quantum number but increases with increasing cylinder radius,while the defect mode FWHM of TM wave changes different.
