摘　　要：利用传输矩阵法研究含一向列相液晶缺陷层的一维Fibonacci第八代准周期结构局域模的电控可调特性.首先建立含一向列相液晶缺陷层的一维Fibonacci第八代准周期结构的物理模型;然后利用传输矩阵法数值计算该结构的透射谱,发现在禁带中存在局域模;最后讨论该局域模及其品质因子随外加电场方向与入射光方向间的夹角θ的变化关系.结果表明:局域模波长随夹角θ的增大而向短波方向移动,局域模的品质因子随夹角θ的减小而增大.The electrical controlled adjustable characteristics of one-dimensional Fibonacci eighth generation quasi-periodic structure contains one nematic liquid crystal defect layer localized modes is studied by transfer matrix method. Firstly, building the physical model of one-dimensional Fibonacci eighth generation quasi-periodic structure contain one nematic liquid crystal defect layer. Then, the transmission spectrum of the structure is calculated by transfer matrix method, found the localized modes exist in the forbidden band; Finally, discussing the localized modes and quality factor with changes in relationships of the direction of electric field and the incident light angle 0. The result shows that ： the wavelength of the local modes shift to the short-wave direction with increase of the angle 0 ; the quality factor of localized modes increases with decrease of the angle 0.
