| 摘 要： | 用传输矩阵法计算模拟掺杂（含缺陷）一维光子晶体模型（ABCnAB）m的透射谱，当n=1，（ABCAB）。的透射谱出现了有规律的共振透射带，具有宽带滤波的特性，当m=10时，（ABCAB）10随缺陷层C的折射率以的变化，禁带中心频率处（1．0ω／ω0）出现了一个带宽由大变小变化的透射带，且每个透射带又分裂为恒定透射率的多个透射峰；当m=10，n为奇数时，模型（ABCnAB）10的透射谱出现奇数个透射带，n为偶数时，出现偶数个透射带，且每个透射带均分裂为9个透射峰。这些特性可用于设计可调性多通道滤波器等。

| Abstract: | The transmission spectra of the model of simulated doping （ including defects） one - dimensional photonic crystal （ABCnAB） m. is calculated by means of the transfer matrix method. When n = 1, the orderly resonance transmission belt emerge in （ABCAB）m of the transmission spectra, which has a broadband filter characteristics; when m = 10, （ABCAB）10 is changed with the viciousness of the defect layer C refractive index nc. In band center frequency （ 1.0ω/ω0 ）, there is a transmission belt whose bandwidth is changed from big to small, and each transmission band is also split into more than one transmission peaks , which have constant transmission rate ; when m = 10, n is odd, there appear odd - numberd transmission belts of vransmision spectra for （ ABCn ）10 photomic crystals ; when n is an even number, there appear even transmission belts, and each transmission belt is divided into nine transmission peaks. These features can be used for the design of multi - channel tunable filter. |
