Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

A completely new structure of light just dropped, called the chiral vortex – and the international team of scientists behind its creation says it could be crucial in developing new drugs and in ...

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 ...

Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.

The Hong Kong University of Science and Technology (HKUST)-led research team has adopted gyromagnetic double-zero-index metamaterials (GDZIMs)—a new optical extreme-parameter material—and developed a ...

(Aitor Diago/Moment/Getty Images) For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as phase singularities or optical vortices, ...

A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

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 ...

Pushing the limits of structured light, physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...
