| 摘 要： | 介绍了时域有限差分法（FDTD）的基本原理,设计了一个由TiO2和SiO2组成的（AB）MA结构一维光子晶体模型（A为TiO2,B为SiO2,M=8）,并对光子晶体中传播的电磁场作了模拟和分析.结果表明：不通过掺杂的方法,只是改变光子晶体的结构参数也可在光子带隙中引入缺陷态,且缺陷态的中心波长和宽度随结构参数的改变而变化.

| Abstract: | The principle of finite difference time domain(FDTD) was presented,A TiO2 photonic crystal(PC) with(AB)MA structure was designed,in the structure A is TiO2,B is MgF2 and M=8,and analysis of electromagnetic field in 1D photonic scrystal(PC) was performed.The results show that without the doping method,it can also introduce the defect state into the photonic band gap only by changing the structural parameter,and the central wavelength and width of the defect state change with the structural parameter. |
