Photons do the twist, and scientists can now measure it

Researchers in the University of Minnesota's College of Science and Engineering have measured the twisting force, or torque, generated by light on a silicon chip. Their work holds promise for applications such as miniaturized ...

Doubling data density

An electronic device that could lead to smaller, low-power memory chips can now be controlled and probed by light, as revealed by research from KAUST.

Researchers devise new tool to measure polarization of light

Researchers from North Carolina State University have developed a new tool for detecting and measuring the polarization of light based on a single spatial sampling of the light, rather than the multiple samples required by ...

Liquid crystals open new route to planar optical elements

Researchers at Osaka University developed a technology to control the light wavefront reflected from a cholesteric liquid crystal - a liquid crystal phase with a helical structure. Although known for their ability to Bragg-reflect ...

Getting a better measure of spin with diamond

Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that ...
