NanoLight

Holography, a revolutionary 3D imaging technique, has been developed for storing and recovering the amplitude and phase of light scattered

We experimentally demonstrate the focusing of visible light with ultra-thin, planar metasurfaces made of concentrically perforated, 30-nm-thick gold films. The

The precise manipulation of a propagating wave using phase control is a fundamental building block of optical systems. The wavefront

Thermodynamically driven self-assembly offers a direct route to organize individual nanoscopic components into three-dimensional structures over a large scale. The

We proposed a metasurface made of tiny gold antennas could act as either a flat mirror or a concave, focusing
