摘要
通过半导体材料的磁光效应可实现光子晶体的磁场调控.本文提出在含有缺陷层的一维光子晶体表面添加具有Voigt效应的磁光半导体表面层,并采用传输矩阵法计算了不同参数下该结构的光学性能.计算结果表明,在合适的结构参数与材料参数下,可实现表面模与缺陷模之间耦合程度的磁场相关性,从而获得由磁场调控的缺陷模透射率与吸收率.
Abstract
Magnetic-field tuning of photonic crystals can be realized through the magneto-optical effects of semiconductors. In this work a configuration is proposed where a semiconductor surface processing the Voigt effect is added to a ID photonic crystal containing a defect layer. The optical properties of this structure for different parameters are calculated by using the transfer matrix method. The results show that for proper structural and material parameters, the degree of the coupling between the surface mode and the defect mode is dependent on the applied magnetic field, leading to a magnetically tunable transmittivity and absorptivity of the defect mode
