In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature.
A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair.
By leveraging the concept of chirality, or the difference of a shape from its mirror image, EPFL scientists have engineered an optical metasurface that controls light to yield a simple and versatile technique for secure encryption, ...
How does a cloud stay cool under direct sunlight—or seem to vanish in infrared? In nature, phenomena like white cumulus clouds, gray storm systems, and even the hollow hairs of polar bears offer remarkable lessons in balancing ...
Blink and you might miss it, but if you keep your eye on the monitors in professor Sebastian Will's lab, you'll catch a series of single-second flashes that light up the screen. Each flash is an atom of strontium, a naturally ...
Optical biosensors use light waves as a probe to detect molecules, and are essential for precise medical diagnostics, personalized medicine, and environmental monitoring.
A new filter for infrared light could see scanning and screening technology tumble in price and size. Built on nanotechnology, the new heat-tunable filter promises hand-held, robust technology to replace current desktop infrared ...
Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.
Â鶹ÒùÔºicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials.
In the nanometer range (billionth of a meter), interactions occur between light and matter that do not happen on larger scales. As such, so-called nanophotonic materials have unique optical properties that open up a whole ...
