摘要
采用光学传输矩阵法首次研究了无序一维三元光子晶体的带隙特性.研究发现,无序结构光子晶体与周期结构光子晶体相比其带隙显著加宽.取无序的介质元数越多,得到的禁带越宽.论文还计算和讨论了无序度和高低折射率之差值对光子晶体带隙的影响.
Bandgap properties of disordered one-dimensional （1D） ternary photonic crystals are investigated by optical transfer matrix method for the first time . The results show that disordered structure provides strikingly extended bandgap compared with the corresponding periodic structure. The more ingredient of disordered dielectric multilayers adopted in the calculation, the wider stop band will be obtained. The influence of degree of disorder D and contrast of high and low refractive indices to the photonic bandgap are also calculated and discussed.
