Journal ArticleDOI
Broadband Light Bending with Plasmonic Nanoantennas
Xingjie Ni,Naresh Kumar Emani,Alexander V. Kildishev,Alexandra Boltasseva,Vladimir M. Shalaev +4 more
TL;DR: Unparalleled wavefront control in a broadband optical wavelength range from 1.0 to 1.9 micrometers is experimentally demonstrated using an extremely thin plasmonic layer consisting of an optical nanoantenna array that provides subwavelength phase manipulation on light propagating across the interface.
Journal ArticleDOI
Metasurface holograms for visible light
TL;DR: Ni et al. as discussed by the authors presented ultra-thin plasmonic holograms that control amplitude and phase in the visible region and are just 30 nm thick, which is comparable to the light wavelength used.
Journal ArticleDOI
An ultrathin invisibility skin cloak for visible light
TL;DR: In this article, an ultrathin invisibility skin cloak is proposed to cover a 3D arbitrarily shaped object by complete restoration of the phase of the reflected light at 730-nanometer wavelength.
Journal ArticleDOI
Loss-free and active optical negative-index metamaterials
Shumin Xiao,Vladimir P. Drachev,Alexander V. Kildishev,Xingjie Ni,Uday K. Chettiar,Uday K. Chettiar,Hsiao Kuan Yuan,Hsiao Kuan Yuan,Vladimir M. Shalaev +8 more
TL;DR: It is experimentally demonstrated that the incorporation of gain material in the high-local-field areas of a metamaterial makes it possible to fabricate an extremely low-loss and active optical NIM.
Journal ArticleDOI
Ultra-thin, planar, Babinet-inverted plasmonic metalenses
TL;DR: Ni et al. as mentioned in this paper developed a plasmonic metalenses that focus a beam of visible light into a spot measuring only slightly larger than the wavelength of operation, achieving a focal length of 2.5 μm at a wavelength of 676 nm.
