摘要
利用传输矩阵法对一维三元光子晶体异质结构的光学特性进行了研究,讨论了介质层厚无序度对三元结构光子禁带的影响.研究表明,将具有相互交叠光子禁带的一维光子晶体叠加构成异质结,可以有效地增大全角度反射的频率范围,当入射角从0°增大到89°,该结构均可实现从0.410 w/w0到0.654 w/w0宽频波段的全反射;相对于二元结构,三元结构可以减小在实际制作过程中随机误差引起的介质层厚无序对光子带隙的影响.该研究结果可为实现可见光及红外光波段大角度反射器的制备及应用提供理论支持.
The reflection characteristics of one-dimensional polyhasic photonic crystals by usingheterostructure were studied by transfer matrix method. The influence of the disorder of three elementcompound dielectric layers was mainly disscused. The results indicate that the heterostructure consists oftwo one-dimensional polyhasic photonic crystals with suitable photonic bandgap can substantially enlargeomnidirectional reflection frequency range. When the incident angle is in the range of 0-4 89%, the bandof total refection can be achieved from 0. 410w/w0to 0. 785w/wv. Completed with the two elementcompound dielectric layers, three element photonic crystals can decrease the influence of the disorderproduced in crystal preparation process. The results provide theoretical support for the preparation andapplication of wide-angle reflector invisible and infrared light band.
