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.

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 ...

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 ...
