Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface ...

A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240159, discusses on-chip light control of semiconductor optoelectronic devices using integrated metasurfaces. Since the initial ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...
