GOTHENBURG, Sweden, June 3, 2008 -- A single laser pulse can reportedly create complex, ordered nanostructure systems, a previously unobserved phenomenon. Chalmers University of Technology (Gothenburg, Sweden) researchers said they have discovered a method for controlling the pattern into which the nanoparticles organize themselves. They said this could have uses in fiber optics, optical sensors and advanced LEDs and lasers. Dinko Chakarov, one of the authors of an article in the journal Nature describing the results, said the researchers started with a layer of disordered nanoparticles of gold or silver on a membrane...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.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
