Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a ...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by “nulling” out the light of the parent star by ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of starlight suppression needed for future space observatories to pick out very ...

Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don't just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These ...

A new Doctoral Network coordinated by Tampere University has secured €4.4 million in funding from the European Union’s Marie Skłodowska-Curie Actions (MSCA) programme. The High-Power Optical Vortices ...

(Nanowerk News) An optical vortex is identified as a phase singularity encircled with helical wavefront, and thanks to its unique properties including its carried orbital angular momentum (OAM) ...

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

Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical ...
