A material built to tell left-handed light from right-handed light has long had a frustrating weakness. It mostly ignored ...

Chiral molecules have structures that cannot be superimposed on their mirror image, like left and right hands. Many ...

Scientists have developed a new type of semiconductor material that can do something unusual: it can tell the difference ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

By harnessing the unique properties of tantala (tantalum pentoxide), a team of US-based researchers has created a photonic integrated circuit that can be tuned to deliver laser light across a broad ...

A dopant molecule accepts electrons from a chiral perovskite host, enabling visible light absorption while preserving the ...

"We can use almost the entire spectrum of light, from visible to X-ray, to manipulate and study materials," Fohtung said. "We can interrogate any system, from hard condensed matter to soft biological ...

Adding zinc ions to lithium niobate crystals cuts the energy needed for polarization switching by 69%, enabling visible-light programming of memristors for brain-inspired computing. (Nanowerk ...
