Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication.

An international team of scientists led by Le Phuong Hoang and Giuseppe Mercurio from European XFEL has unveiled a new way to ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

Ferroelectrics are seen as promising candidates for the electronics of tomorrow. An experiment at the world's largest X-ray laser—the European XFEL in Schenefeld near Hamburg—now shows that their ...
