Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, ...

To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of these ...

Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic ...

Researchers have unveiled a novel concept termed 'supercritical coupling' that enables several folds increase in photon upconversion efficiency. This discovery not only challenges existing paradigms, ...

Using a groundbreaking new technique, researchers have unveiled the first detailed image of a photon — a single particle of light — ever taken. When you purchase through links on our site, we may earn ...

Assistant Professor of Biomedical Engineering Yi Xue works on 2P-FOCUS, a new two-photon microscopy system, in her lab. The system promises novel insights into biological features that were once only ...

"It's a sheer physical challenge to construct sieves with such precision." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. To truly understand ...

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely ...
