A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new ...

Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that's hard to intercept.

A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a ...

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

Ultraviolet or infrared light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. UV (100–400 nm) and NIR (0.75–1.4 μm) ...

When a predator like a lion walks through the grasslands, it makes its presence known by roaring, which can be heard miles away. Since the lion is at the top of the food chain, it doesn’t particularly ...
