This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

The proposed vortex beam can carry vast amounts of information, making them ideal for dense data communication systems. Scientists have developed a breakthrough optical technology that could ...

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

Propagate light through any kind of medium -- be it free space or biological tissue -- and light will scatter. Robustness to scattering is a common requirement for communications and for imaging ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams. Nature Photonics today published research by a team from South ...

There’s a new kind of twisted light. A rotating “vortex beam” whose twist changes across the length of the beam has been created in the lab for the first time. Researchers discovered in 1992 that a ...

American and Israeli researchers have used twisted vortex beams to transmit data at 2.5 terabits per second. As far as we can discern, this is the fastest wireless network ever created -- by some ...

The future of imaging extremely small objects may come down to doughnut-shaped beams of light, according to a study from researchers at JILA and the Department of Physics. The study explored the ...
