MOSCOW, Jan. 27, 2020 — Scientists from the Skolkovo Institute of Science and Technology (Skoltech), in collaboration with researchers from the Shanghai Institute of Optics and Fine Mechanics and the Helmholtz Institute, have proposed a way to generate intense, short, twisted pulses in the ultraviolet (UV) range to aid scientists in their investigation of new materials. Although optical angular momentum (OAM) beams can be readily derived from Gaussian laser beams with phase plates or gratings, achieving OAM is more challenging in the extreme ultraviolet (XUV) range. The Skoltech team theoretically and...Read full articleRelated content from Photonics MediaARTICLESImproving Photoluminescence in Silicon Boosts PIC PerformanceResearchers in Russia have increased photoluminescence (PL) in silicon using germanium quantum dots and a specially designed silicon photonic crystal.
