  • Plasmon induced transparency in cascaded pi-shaped metamaterials
    [作者:Cetin, AE; Artar, A; Turkmen, M; Yanik, AA; Altug, H,期刊:OPTICS EXPRESS, 页码:22607-22618 , 文章类型: Article,,卷期:2011年19-23]
  • We experimentally and numerically demonstrate a planar metamaterial consisting of two asymmetrically positioned pi-structures in a single unit that exhibits plasmonic analogue of electromagnetically induced transparency ...
  • Optically-induced-potential-based image encryption
    [作者:Chen, BC; Wang, HZ,期刊:OPTICS EXPRESS, 页码:22619-22627 , 文章类型: Article,,卷期:2011年19-23]
  • We present a technique of nonlinear image encryption by use of virtual optics. The image to be encrypted is superposed on a random intensity image. And this superposed image propagates through a nonlinear medium and a 4-...
