利用传波矩阵方法,计算了电磁波在带有缺陷的一维光子晶体中的传波。数值计算表明,在只有一个缺陷层时,缺陷模式频率与缺陷层在光子晶体中的位置无关,当有两个缺陷层出现时,缺陷模式频率与缺陷层在光子晶体中的位置是有关的。另外,计算也表明,缺陷模式频率对缺陷层材料的折射率变化是非常敏感的。 The propagation wave of electromagnetic wave in a one-dimensional photonic crystal with defects was calculated by using the transfer matrix method. Numerical calculations show that the frequency of the defect mode is independent of the position of the defect layer in the photonic crystal when there is only one defect layer. When two defect layers occur, the defect mode frequency is related to the position of the defect layer in the photonic crystal. In addition, the calculation also shows that the defect mode frequency is very sensitive to the refractive index change of the defect layer material.
