中文摘要：
对二维介质柱光子晶体耦合腔波导慢光结构进行了研究,发现随着缺陷腔之间晶格个数增多,群速度减小很快,选用7×7超胞单元时耦合腔波导结构的导模最大群速度νg-max只有光子晶体线缺陷波导的1/251.然后对7×7超胞单元的缺陷腔周围四个介质柱半径进行调整,发现新型结构导模的νg-max进一步减小,最小可达到5.89×10-4c,约为未调整之前的1/5.最后通过比较发现,当改变缺陷腔上下相邻两个介质柱半径时得到的结构具有更好的慢光特性.
英文摘要：
The structure of 2D rods PhC CCW is studied,and it is found that the group velocity discreases quikly with the increase of lattice number between two rod defects. When 7×7 supercell unit is chosen,the largest group velocity ν g-max of the guided mode is about 1/251 times that of photonic crystal line defect waveguide. Radius of the four rods around the cavity of the 7×7 supercell unit are adjusted,ν g-max of the new strcture can reach 5.89×10-4 c,and it＇s about 1/5 that of unadjusted structure. Finally,by making comparisons,it is found that the structure has the best slow-light characteristic when the radius of the up and down rods are changed.
