摘　　要：基于二维正方晶格光子晶体与十二重Stamfli型光子准晶提出了单环形腔上下载滤波器及双环形腔串联上下载滤波器.分析并对比了两种上下载滤波器的传输效率随光子准晶介质柱半径及折射率大小的变化规律,且对比了两种上下载滤波器的品质因数随环形腔中心介质柱半径及折射率大小的变化规律.结果表明,双环形腔串联复合型上下载滤波器的性能优于单环形腔复合型上下载滤波器.研究结果将为设计及制备优良上下载滤波器件提供一定指导作用.In this paper, based on two-dimensional square lattice photonic crystal and twelve-fold Stamp- fli-type photonic quasicrystal （PQC）, a single-ring-cavity add-drop filter and a double-ring-cavity-cas- cade add-drop filter are proposed. The dependence of the transmission efficiency of the two filters on the radius and the refractive index of the dielectric rod in the PQC were analyzed and compared. The dependence of the quality factor of the two filters on the radius and the refractive index of the dielectric rod in the center of the ring-cavity were also analyzed and compared. The results show that the per- formance of the double-ring-cavity-cascade add-drop filter is better than that of the single-ring-cavity add-drop filter. The research results will be helpful for the design and the fabrication of the high-quality add-dron filter devices.
