摘要
利用传输矩阵方法,研究了金属Ag插层对C60/AlN一维光子晶体带隙宽度以及反射率的影响.结果表明:在C60与AlN之间插入Ag组成的[C60/Ag/AlN]n一维光子晶体,与未插入Ag层相比可使带隙增宽73.91%,最大反射率提高到91.01%.该结构可望用于制作紫外线波段的宽带反射镜.
The photonic band structure of one-dimensional metallic cladding photonic crystals was simulated by the transfer matrix method (TMM). By inserting metal Ag layers between C60 and AlN layers,a new metallic cladding photonic crystal (C60/Ag/AlN), could be made. The new structure shows a wider band gap than in the structure of (C60/AlN)n in UV region. The modes can broaden the band gaps by 73.91% and exhibit a high reflectivity of 91.01%. The metallic cladding photonie crystals is ideal candidates for making reflector. The characteristics of ttie structure could be used in a low-loss broad band reflector.
