A photodetector is a kind of optoelectronic device that can detect optical signals and convert them into electrical signals, which includes photodiodes, phototransistors and photoconductors, et al.

Scientists have long been fascinated by how light interacts with matter. At the heart of this curiosity are photons—particles that carry light—as they pass through different materials. When photons ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

These devices are made by depositing a thin film of organic molecules onto a substrate that acts as an electrode, and function by controlling the transfer of electrons between the thin film and the ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Imagine a light switch so small it is made from just a few atoms, and so precise it releases light one particle at a time. These tiny switches, called quantum emitters, are considered one of the core ...

A fast-growing UK startup is quietly making strides in the promising field of quantum photonics. Cambridge-based company Nu Quantum is building devices that can emit and detect quantum particles of ...

This article presents a method for developing elastic nanoarchitected metamaterials with tunable optical responses.

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Osaka, Japan – Organic electronics is a field that has garnered significant interest in academic and industrial circles due to its potential applications in OLEDs and organic solar cells, offering ...
