In 1905, Einstein proposed the photon theory of light. According to this, light consists of discrete packets of energy called photons. His work on the photoelectric effect introduced us to wave ...

Researchers in Birmingham have created the first image of a photon, a lemon-shaped particle of light emitted from the surface of a nanoparticle. The theory that made this image possible ...

Attosecond photonics is very exciting because it allows the creation of very strong, short intense pulses that allow new types of interaction of light with ... deeply what a photon is and what ...

In the process, their experiment included photons in 37 dimensions, taking science even further down this strange quantum ...

A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. Disclaimer: AAAS and ...

A team of physicists affiliated with multiple institutions in China has measured a pulse of light in 37 dimensions. In their ...

The detection of light at the single-photon level is important for tasks ranging from fluorescence imaging to quantum information processing, reports Neil Savage. High-sensitivity detectors that ...

By alternating the direction of the slabs in the stack, the device manipulates light in a way that enables photon pair generation at miniscule length scales. "Once we understood how amazing this ...

Photon upconversion involves a series of non-linear optical ... and deeper tissue penetration due to their ability to convert near-infrared light to visible or ultraviolet light. These properties make ...
