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 ...
Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...
Ultraviolet and near-infrared light are widely used in modern technologies but are invisible to the human eye. Researchers ...
A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...
