| 摘 要： | 基于三分Cantor分形多层序列结构,设计了一种一维光子晶体耦合腔结构.用传输矩阵法研究了当引入的缺陷介质为负折射率材料时,该晶体耦合腔的传输谱和场局域化特征;在透射谱中得到了一个半高宽仅为0.19 nm的超窄透射窗口,通过曲线拟合得出了缺陷层折射率与超窄透射窗口位置之间的非线性解析关系.新耦合腔结构在光通信超密集波分复用和光学精密测量等领域中有一定的应用价值.

| Abstract: | A photonic crystal coupled-resonator based on fractal Cantor multilayer with G=3 and N=3 is obtained.Optical properties of transmission and field localization of the new structure are studied by using transfer matrix method when the defect layer is a negative refractive index material.A supper narrow transmission window,which half width is only 0.19 nm,appears in the band gap.The nonlinear relationship between the negative-index of the defect and the position of the super narrow transmission window is also obtained by method of curve fitting.The new photonic crystal coupled-resonator has important applications in supper dense wavelength division multiplexing for optical communications and precise optical measurement. |
