Virus-Sized Laser Defies Diffraction Limit

Facebook X LinkedIn Email
EVANSTON, Ill., Nov. 6, 2012 — The bow tie is a popular shape for pasta and maybe soon it will be for laser cavities, too. Single-laser devices the size of virus particles operate at room temperature and defy the diffraction limit, thanks to a lasing cavity composed of 3-D bow-tie-shaped metal nanoparticle dimers. The plasmonic nanolaser, designed at Northwestern University, could be integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors. Reducing the size of photonic and electronic elements is critical for ultradense information storage and ultrafast data processing....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...
