摘要
基于三维光子晶体在传输器件、通讯信息传输、光子晶体滤波器等方面的应用,设计了金刚石结构、面心立方结构和木堆结构构成的三维光子晶体结构,应用平面波展开发计算了三种结构随填充率变化时带隙的变化规律。结果表明,金刚石结构出现较大的带隙率,面心立方结构不易出现较大带隙率,而木堆结构会在较大的一个范围出现完全带隙结构。为三维光子晶体器件的设计提供了理论依据。
The three-dimensional photonic crystal can be used in transmission devices, communication and information transmission, photonic crystal filters, etc. Diamond structure, face-centered cubic structure and the wood pile structural composition of three-dimensional photonic crystal structure were designed. The rule of variation band gap has been obtained with filling ratio variation on three kinds of structures by using the plane-wave expansion method. The results show that the structure of diamond will produce larger band-gap ratio, face-centered cubic structure will be difficult to produce larger band gap rate. The wood pile structure will produce in the larger scope of a full band gap structure. This research provides a theoretic basics for the development of three-dimensional photonic crystal.
