Photonics is the study of the generation, detection, and manipulation of light waves in the form of photons. One interesting property of light is polarization, defined by its electric and magnetic ...

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 ...

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 ...

This “universal technique” may have major applications linked to the control and analysis of different properties for 2D and 3D materials, which can in turn enable the advancement of cutting-edge ...

An international team of researchers reports in Nature a new method that achieves valley polarization in centrosymmetric bulk materials in a non-material-specific way for the first time. This ...

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 ...
