Metasurface Holograms Reconstruct High-Resolution 3D images

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

Metasurface Creates Ultrathin Tiny Planar Lenses

Metasurface Creates Ultrathin Tiny Planar Lenses

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

Metasurface Bends Boardband Light into Arbitrary Directions

Metasurface Bends Boardband Light into Arbitrary Directions

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

Outsmarting Thermodynamics Allows Self-Assembly of Optical Metamaterials

Outsmarting Thermodynamics Allows Self-Assembly of Optical Metamaterials

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

Metasurface Generates Quantum Interference at a Distance

Metasurface Generates Quantum Interference at a Distance

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

About Us

The prime goal of our laboratory is to explore the frontiers of science and technology in tailoring and manipulating light-matter interactions. We strive to pursue solid experimental work in addition to theoretical modeling. Our research focuses on the interaction of light with nanostructures and nanomaterials that leads to exotic electromagnetic properties, which could be applied to the field of photonics, metamaterials, plasmonics, quantum optics, spintronics, optoelectronics, energy, acoustics, imaging, sensing, and biology.
