Generating entangled photons with nonlinear metasurfaces

Illustration of a metasurface generating pairs of photons (shown as spheres).  The photon entanglement can be varied by changing the pump beam (shown in red). Illustration by Andrei Komar & Matthew Parry. Subhed: A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions—an important step towards creating miniaturized […]

Bright idea: new LEDs can detect off food and lethal gases

Your smart device could soon be even smarter with a new infrared light emitting diode (LED) that is ‘tuneable’ to different wavelengths of light – it could enable your fridge to tell you when your food is going off and your phone to tell you if that Gucci purse is real. Researchers from TMOS have […]

Reimagining medical diagnostics in developing countries: meta-optics offers a new way to look inside cells

Developing countries face many challenges in the fight against infectious diseases. One of these is the lack of access to medical diagnostic tools. This is considered a key reason why malaria and tuberculosis are still two of the leading causes of death in sub-Sahara Africa and parts of Asia. In order to address issue of […]
