摘　　要：利用传输矩阵方法,研究了(AB)^(N_(ab))(BA)^(N_(ba))一维光子晶体的光子带隙和缺陷模的变化特征。首先,研究了垂直入射时,缺陷模共振线宽和透过率随光子晶体周期数变化的关系。然后,通过改变介质折射率和几何长度实现了光子带隙宽度、缺陷模的波长位置和透过率的可调谐性。最后给出了缺陷模峰值波长和透过率随入射角的变化。Based on transfer matrix method （TMM）, properties of photonic band-gap and defect mode are in- Nab Nba vestigated in one dimensional photonic crystals with （AB） （BA） configuration. Firstly, both the resonance line width and transmittance of defect mode are investigated with various periodic numbers in the case of normal incidence. And then, the tunability of bandgap width, defect mode wavelength, and transmittance is realized by changing the refractive index and length of media. Finally, both wavelength and transmittance of defect mode are given for various incidence angels.
