Over time researchers have found fewer of the insects turning up in light traps, suggesting they may be less attracted to some kinds of light than they once were. By Veronique Greenwood It used to be ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the ...

Physicists at Peking University have uncovered a new way to confine light far beyond conventional limits — without relying on ...

(Nanowerk News) Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar sensing, and medical imaging. However, the widespread adoption of ...

WARSAW: Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometres thick--over 1,000 times thinner than a human hair. By using a unique material with ...

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take ...
