Scientists have discovered novel optical properties in arsenic trisulfide (As2S3), a crystalline van der Waals semiconductor.

Crystalline arsenic trisulfide shows record photorefractive response and can be laser-patterned at 500-nm resolution without ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major ...

Optical illusion puzzles have been there for centuries and these are fun challenges that are designed to play tricks on our eyes and brains. Optical illusions work on a simple principle where it ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. This image is seen as a Radiating Wavy Pattern Optical Illusion that appears ...

Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of ...

The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...

Bespoke manipulation of light by Steve Johnson's group could find uses in cellphone lenses, smart-car sensors, optical fibers. Mathematicians at MIT, Cambridge, Ma, have developed a new computational ...
