Journal ArticleDOI
Three-dimensional optical holography using a plasmonic metasurface
Lingling Huang,Lingling Huang,Xianzhong Chen,Holger Mühlenbernd,Hao Zhang,Shumei Chen,Shumei Chen,Benfeng Bai,Qiaofeng Tan,Guofan Jin,Kok Wai Cheah,Cheng-Wei Qiu,Jensen Li,Thomas Zentgraf,Shuang Zhang +14 more
TL;DR: Huang et al. as mentioned in this paper developed ultrathin plasmonic metasurfaces to provide 3D optical holographic image reconstruction in the visible and near-infrared regions for circularly polarized light.
Journal ArticleDOI
Dual-polarity plasmonic metalens for visible light
Xianzhong Chen,Lingling Huang,Lingling Huang,Holger Mühlenbernd,Guixin Li,Benfeng Bai,Qiaofeng Tan,Guofan Jin,Cheng-Wei Qiu,Shuang Zhang,Thomas Zentgraf +10 more
TL;DR: A counter-intuitive dual-polarity flat lens based on helicity-dependent phase discontinuities for circularly polarized light is experimentally demonstrated by controlling the helicity of the input light, and the positive and negative polarity are interchangeable in one identical flat lens.
Journal ArticleDOI
Dispersionless Phase Discontinuities for Controlling Light Propagation
Lingling Huang,Xianzhong Chen,Holger Mühlenbernd,Guixin Li,Benfeng Bai,Qiaofeng Tan,Guofan Jin,Thomas Zentgraf,Shuang Zhang +8 more
TL;DR: This work investigates the interaction of circularly polarized (CP) light at an interface composed of a dipole antenna array to create spatially varying abrupt phase discontinuities and designs and experimentally demonstrates an ultrathin phase gradient interface to generate a broadband optical vortex beam based on the above principle.
Journal ArticleDOI
Helicity dependent directional surface plasmon polariton excitation using a metasurface with interfacial phase discontinuity
Lingling Huang,Lingling Huang,Xianzhong Chen,Benfeng Bai,Qiaofeng Tan,Guofan Jin,Thomas Zentgraf,Shuang Zhang +7 more
TL;DR: Huang et al. as mentioned in this paper demonstrated a reconfigurable, unidirectional coupling scheme for excitation of collective oscillations of the electrons at a metal surface, the so-called surface plasmon-polaritons.
Journal ArticleDOI
Helicity Dependent Directional Surface Plasmon Polariton Excitation Using A Metasurface with Interfacial Phase Discontinuity
Lingling Huang,Lingling Huang,Xianzhong Chen,Benfeng Bai,Qiaofeng Tan,Guofan Jin,Thomas Zentgraf,Shuang Zhang +7 more
TL;DR: In this article, the authors apply the concept of interfacial phase discontinuity for circularly polarizations on a metasurface to the design of a novel type of polarization dependent surface plasmon polaritons unidirectional excitation at normal incidence.
