| 摘 要： | 根据介质的光弹效应，采用有限元法对二维光子晶体的能带特性进行分析。当给二维光子晶体施加应力时，由于构成二维光子晶体的介质的光弹效应，引起介质的折射率变化，使得光子晶体的能带结构发生变化。详细分析了外加应力变化对基于Si/SiO2二维光子晶体能带结构特性的影响，结果表明，禁带的起始波长、截止波长及禁带宽度的变化量与外加应力呈线性关系。

| Abstract: | In terms of photoelastic effect of medium,the band characteristics of two-dimensional(2D) photonic crystals were analyzed by finite element method.The photoelastic effect of the medium composing 2D photonic crystals causes change of its refractive index when imposed by stress,the band structure of 2D photonic crystals varies accordingly.The effect of stress on the structural characteristics of band gap in 2D Si/SiO_2 photonic crystals was analyzed in detail.And for each band gap,the variation of start wavel... |
