| 摘 要： | 基于Mie散射理论和低浓度近似,对磷化镓光子晶体的安德森定域化进行了理论计算,并分析了影响定域化参量的各种因素。结果表明,在浓度为10%,折射率比值大于3.8,无吸收状态下,中红外区出现了安德森定域化现象,并且随粒子半径的增大,定域化区向长波段移动,且基质折射率的增大使定域化现象减弱。研究结果为该类晶体的定域化现象提供了理论参考。

| Abstract: | Based on the Mie scattering theory and the low density approximation, we studied on Anderson localization of GaP photonic crystal. The results show that the photonic crystal of GaP has photonic forbidden band in middle infrared with the condition of density of 10% and the ratio of refractive index is larger than 3.8 and without the absorption. And we analyzed the factors which influencing on the Anderson localization parameter. So we can provide theory reference to research Anderson localization of GaP photonic crystal. |
