具有缺陷的光子晶体,光子频率带隙内将出现局域模,而线缺陷相应地形成一个传输效率很高的光波导.计算了空气中Al材料的旋转四边形直柱光子晶体存在线缺陷时的带结构和态密度,给出了二维方形光子晶体的波导的TM模的电场分布,并讨论了波导耦合的传输效率.
A photonic crystal with defects will appear some localized modes in photonic frequency gap,and the linear defects will cause the formation of a waveguide with high transmission efficiency.The photonic band structure and the density of the state of a two-d
