Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of ...

Those of us who grew up watching Luke and Leia on screen have probably wondered at one point or another why we don’t have lightsabers. The basic reason why is because the photons that make up light do ...

Photons, the elementary particles that make up light, are known to be fast, weightless and to not interact with each other. But in new experiments, physicists at MIT and Harvard have now created a new ...

It's a glimpse of science fiction made fact: Scientists have created a new form of light that could someday be used to build light crystals. But before would-be Jedis start demanding their sabers, the ...

“Molecules” made from three photons have been created by physicists in the US. The photon triplets were made by firing laser light into an atomic gas and the researchers believe that their technique ...

Researchers have developed a novel way to entangle two photons -- one with a wavelength suitable for quantum-computing devices and the other for fiber-optics transmissions. Some of the most advanced ...

Up until the mid-20 th century, light was pretty ordinary. Yes, it was both a particle and a wave, but it didn’t do anything very weird. Then scientists, under-employed after the end of World War II, ...
