Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...

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

It has long been considered common sense that a single device performs only one function. Just as tuning a radio to a ...

Research led by Oleg Mitrofanov, professor of Terahertz Photonics in University College London (UCL) has demonstrated a new approach for aligning the emission wavelengths of individual GaAs quantum ...

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...

Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a ...

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 ...

Metalenz announced today that chip giant ST Micro’s latest product incorporates its metasurface technology that puts flat lenses in consumer products like smartphones, laptops, smart home devices, ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...
