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

In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three ...

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

For the first time, physicists have observed that 'holes' in light can move faster than the light itself.

Light is not supposed to behave like a trapped whirlpool, yet researchers have now shown that it can do exactly that inside a ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next ...

A method for configuring light-trapping devices promises better optical nanodevices by amplifying light and enhancing the emission efficiency of luminescent nanomaterials — without the need for ...

To carry information over long distances, the fiber must be extraordinarily clear. The magic behind an optical fiber’s transparency is a combination of material science and manu ...

We live in a world bathed in light. We see with light, plants draw energy from light, and light is at the core of technologies from computing to surgical techniques. The field of optics, the subject ...

A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics ...
