中文摘要：

对色散介质层采用洛仑兹振子模型，通过考虑色散介质层两边的边界条件，可以严格得到表征色散介质层的转移矩阵。通过改变介质层的不同参数，详细研究了含增益型色散介质的对称光子晶体的简正耦合模。

英文摘要：

The transfer matrix,which represents the dispersive by using Lorentz model and considering boundary conditions. medium＇s layer, can be rigorously obtained The detailed investigation on normal coupled mode in a symmetric photonic crystal with dispersive medium＇s layer is presented by adjusting parameters of the dispersive medium＇s layer.
