Plasmon Laser Demonstrates Fastest Switching Speed

Facebook X LinkedIn Email
LONDON and JENA, Germany, Oct. 9, 2014 — A new plasmon semiconductor laser has demonstrated ultrafast switching speeds and is being touted as the world’s fastest. The laser was created at Imperial College London and Friedrich Schiller University Jena using semiconductor nanowires with a surface made of zinc oxide, rather than a conventional glass surface. This new ultrafast laser is the fastest to date, the researchers said, with the ability to turn on and off at one thousand billion times per second — a thousand times faster than existing lasers. Researchers demonstrate ultrafast laser response time....Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
