Calculations intended to feel out the interactions between light and the material that produces it may inadvertently describe the photon's outline, revealing its shape in unprecedented detail. A new ...

Nonlinear optical dynamics—intensity-dependent response of light upon interaction with materials under high-intensity light sources—are of huge significance in modern photonics, finding applications ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser.

Photons are massless quantum particles that form light. They travel at incredible speeds and interact with various forms of matter. The emission of photons from atoms and molecules can lead to an ...

Operating at room temperature, this nanoscale device leverages silicon photonics to achieve high-performance spin control, essential for quantum communication.

Lighten up, people: a fascinating new paper has dropped that describes the shape of a single photon, the smallest possible form of energy in an electromagnetic field that we commonly know as light.

The increasing demand for advanced optoelectronic devices necessitates the development of materials that can efficiently absorb and manipulate light at the nanoscale. This research explores the unique ...
