A research team in China has built a quantum dot device that produces photon pairs with record-setting purity, achieving a two-photon fraction of 0.983(1). The work, published in Nature Materials, ...

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.

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 ...

Multiphoton microscopy is used in biomedical research to study cells and tissues. Today, so-called two-photon microscopy is used to study processes within cells, but the technique has limitations in ...

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 ...

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 ...

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 ...

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 ...
