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 ...

(Nanowerk News) A new publication from Opto-Electronic Advances ("Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography"), discusses tailoring ...

The PBG group of Department of physics, Fudan university, recently proposed a method using a reflective photonic crystal slab to generate vortex with high conversion efficiency and without an ...

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 ...

Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular ...

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 ...

Researchers at the University of Southern California, building on its previous work on infinity-capacity twisted laser vortex networks, has now adapted its technology to work with boring ol' radio ...

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 ...

Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly ...
