Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...

Abstract: In this letter, a low-loss and nonvolatile phase-modulated metasurface based on germanium telluride (GeTe) is proposed operating in the Ka band. The main functional part of the element is ...

Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light ...

Abstract: This paper presents a novel wireless-optical interconnection scheme employing cascaded transmissive and reflective metasurfaces to overcome the switching capacity limitations of conventional ...
