摘　　要：利用传输矩阵方法,研究了由两种具有特定散射关系的一维光子晶体交替排列所形成的一维光子晶体超晶格的光学特性,讨论了势垒宽度,势阱宽度及势阱数目对其的影响.计算结果表明,通过改变超晶格的结构,可以调节在光子禁带中透射带的数目、透射带中透射峰的数目,并且这些透射峰都具有很高的品质因子.这种光子晶体超晶格结构有望作为多通道滤波器在密集波分复用系统及集成光学系统中获得应用.Using transfer matrix method, we study the optical properties of a photonic crystal superlattice which is formed by stacking two photonic crystals with proper dispersion relation. The influence of the barrier layer thickness and the well layer width is discussed. It is found that the number of transmission bands and transmission peaks in each band can be tuned by adjusting superlattice structure and each transmission peak possesses high quality factor. This structure opens a promising way to fabricate multiple-channeled filters for dense wavelength division system and the integrated optical system.
