A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped ...

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 ...
