A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...

In a new Nature Physics study, researchers created particle-like so-called “vortex knots” inside chiral nematic liquid crystals, a twisted fluid similar to those used in LCD screens. For the first ...

Researchers said these optical vortices could help overcome bandwidth limitations in fibre optic communication, or enhance the optical tweezers that can manipulate atoms. Researchers have created an ...

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 ...

The entirely new structure of light could help drug developers see their work more clearly than before. An entirely new structure of light is helping to measure chirality in molecules more accurately ...

Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. Researchers at USC, JPL and Tel Aviv University have managed to transfer 2.56 terabits of information ...

Photons, in the form of optical pulses, radio waves, and the like, have been used to transmit data for decades. The next phase will probably involve using the quantum states of the photons themselves ...
