| 摘 要： | 针对正方晶格光子晶体因带隙特性较差而使其应用受到一定限制的问题, 设计一种新型内嵌结构式二维光子晶体, 即在普通正方晶格光子晶体内部嵌入同类晶格的光子晶体。同时对介质柱型和空气孔型光子晶体分别进行了仿真实验。结果表明, 采用内嵌结构式光子晶体后, 无论是介质柱型还是空气孔型光子晶体, 都较普通正方晶格光子晶体的带隙条数增加2～10条, 带隙率也均有了显著提升。该方法是进一步寻求完全禁带正方晶格光子晶体结构的有效方法。

| Abstract: | Because the PBG (Photonie Band Gap) of Square lattice photonic crystal has some disadvantages, its application has been limited. A new photonic crystal of embedded structure, which has been embedded in the gaps of square lattice with the same kind of square lattice, has been researched and designed. Both the substrate columnand air hole types with this new structure have been studied. The simulated experiment results show that the number of band gaps is increased by 2～10 with this new structure, the band gap rate is also increased observably. A new way has been found, which can get complete forbidden bands of square latt
ice photonic crystals. |
