Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused ...

Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development ...

Learning from the attempted rescue of the Lunar Trailblazer: how ground-based optical observations and laboratory ...

Quantum-based systems promise faster computing and stronger encryption for computation and communication systems. These systems can be built on fiber networks involving interconnected nodes which ...

A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

To unlock materials of the future, including better photocatalysts or light-switchable superconductors, researchers need to understand how the valence electrons within materials respond to light at ...

A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared to move faster than light itself, darting through a wave field before ...
