Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...
EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials emit polarized light over time. Subscribe to our newsletter for the latest sci ...
A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...
A device produces green light while a researcher in lab gear stands in the background. This OLED device, which is held by a mechanical support, is producing circularly polarized light. Credit: ...
Tsukuba, Japan—Some beetles, such as Anomala albopilosa, strongly reflect left circularly polarized light (electromagnetic waves that oscillate leftward relative to the direction of light reception).
Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...
Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new tools for nanoscale photonics. (Nanowerk Spotlight) Directing light along ...
A Murdoch University researcher in Australia has determined that large-scale solar farms affect migratory routes of wildlife due to polarized light pollution, but this could be improved with ...
