中文摘要：
通过二维方形与二维三角晶格光子晶体光纤能带的对比,选取二维三角晶格作为研究对象。介电常数的周期性在光子晶体中可以形成特殊的光子禁带,进而控制光子的运动状态。基于此,提出了一种单线缺陷光子晶体波导结构,通过分析其含有线缺陷时的能带结构及其色散关系、对群速度的影响等,使其有效慢光区域的GVD位于105～106量级。通过动态变化介电常数和晶格半径,实现动态可调的群速度,可以将群速度动态调节到0.1 c以下,同时仿真验证了影响群速度改变的根本因素为缺陷带频率的变化。
英文摘要：
By comparing the energy band of 2D photonic crystal with square and triangular lattice,the 2D tri angular lattice for the study is selected.The photonic band gap（PBG） can be formed by the periodicity of the per mittivity in the photonic crystal,and then the movement of the photon is controlled.The single-line-defect pho tonic crystal waveguide is proposed,the effect of the energy band structure and dispersion relation with the line defect on the group velocity is analyzed,and the group velocity dispersion（GVD） of the effective slow-light re gion is at 105 ～ 106.To realize the dynamic adjustment of group velocity,the permittivity and the lattice radius are changed,the group velocity can be adjusted to below 0.1c.The simulation shows that the fundamental factors im pacting the group velocity is the changed frequency of the defect band.
