Metasurfaces – planar arrays of subwavelength nanostructures – enable unprecedented control of electromagnetic fields. A particularly intriguing phenomenon in this context is the formation of bound ...

A thermal metasurface is made of a single layer of nanostructured silicon (gray) on top of glass (blue) and a metal mirror (gold). The nanostructured surface is specifically tailored so that it ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature. Photons are ...

Polarization and holographic information become entangled in a quantum hologram. Holographic letters demonstrate entanglement through polarization of paired photons. By selecting different polarizer ...

Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular ...
