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.

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 at Tokyo Institute of Technology (Tokyo Tech, Japan) and Institute of Photonic Sciences (ICFO, Spain) develop a method to generate circularly polarized light from the ultimate symmetrical ...

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 ...

The Polarization Analyzers of series SK010PA are comprehensive universal measurement and test systems for free beam applications and fiber-coupled laser radiation. As a plug&play devices they connect ...

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 ...
