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 ...

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 ...

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 ...

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 ...
