A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...

Researchers at the University of Oulu has introduced an approach using near-infrared (NIR) light beyond light therapy for facilitating simultaneous wireless power transfer and communication to ...
