The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

With the terahertz scope, the team observed a frictionless “superfluid” of superconducting electrons that were collectively ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...
