Scientists set record for light-matter interaction

An international team of physicists from the Mandelstam Institute for Theoretical Physics at Wits University and the Institut Néel in Grenoble, France, has created a tiny superconducting circuit that mimics the quantum mechanical ...

All-optical diffractive neural networks process broadband light

Diffractive deep neural network is an optical machine learning framework that blends deep learning with optical diffraction and light-matter interaction to engineer diffractive surfaces that collectively perform optical computation ...

Researchers demonstrate attosecond boost for electron microscopy

A team of physicists from the University of Konstanz and Ludwig-Maximilians-Universität München in Germany have achieved attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave ...

Controlling photons with a photon

Photons are considered to be ideal information carriers and expected to play important roles in quantum communication and information processing, where quantum mechanics allows for absolutely secure cryptographic key distribution ...

Fresnel lenses: High contrast and efficient focusing

The first Fresnel lens was installed in 1823 in the Cordouan lighthouse, where its beam was visible for 32 km. Since then, this lens design has been used in lighthouses, traffic lights, automobile headlights, magnifying glasses, ...

Interaction between light and sound in nanoscale waveguide

Scientists from Ghent University and imec announce today that they demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these scales – and ...

Green hydrogen: 'Rust' as a photoanode and its limits

Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called ...
