Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

Eyes in space to spot bushfire danger zones

Scientists at the Australian National University (ANU) will lead the development of the first Australian satellite designed to predict where bushfires are likely to start and those that will be difficult to contain.

Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

Nanostructures taste the rainbow

Engineers at Caltech have for the first time developed a light detector that combines two disparate technologies—nanophotonics, which manipulates light at the nanoscale, and thermoelectrics, which translates temperature ...

NASA delivers detectors for ESA's Euclid spacecraft

Three detector systems for the Euclid mission, led by ESA (European Space Agency), have been delivered to Europe for the spacecraft's near-infrared instrument. The detector systems are key components of NASA's contribution ...
