Ultrafast plasmonics for all-optical switching and pulsed lasers

Plasmonics is playing a crucial role in advancing nanophotonics, as plasmonic structures exhibit a wide range of physical characteristics that are benefited by localized and intensified light-matter interactions. These properties ...

How we could snoop on extraterrestrial communications networks

The conditions for life throughout the universe are so plentiful that it seems reasonable to presume there must be extra-terrestrial civilizations in the galaxy. But if that's true, where are they? The Search for Extra-terrestrial ...

Researchers boost signal amplification in perovskite nanosheets

Perovskite materials are still attracting a lot of interest in solar cell applications. Now, the nanostructures of perovskite materials are being considered as a new laser medium. Over the years, light amplification in perovskite ...

NASA's Europa probe gets a hotline to Earth

NASA's Europa Clipper is designed to seek out conditions suitable for life on an ice-covered moon of Jupiter. On Aug. 14, the spacecraft received a piece of hardware central to that quest: the massive dish-shaped high-gain ...
