  1. Physicists Build Reversible Laser Tractor Beam
    10/20/2014

    Laser physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam that is bright around the edges and dark in its centre.

  2. Winning By Losing
    10/20/2014

    What started out as a mathematical oddity, has now become a new kind of laser technology. Two years ago, physicists at TU Wien predicted a paradoxical laser effect: Under certain conditions, a laser can be switched on not by supplying it with more energy, but by taking energy away from the laser.

  3. OSA Kicks Off International Year Of Light Educational Efforts At Frontiers In Optics 2014
    10/17/2014

    The Optical Society (OSA) recently announced that its annual meeting, Frontiers in Optics (FiO) 2014, taking place next week in Tucson, Arizona, USA, will serve as the launch for its extensive educational outreach associated with the 2015 International Year of Light (IYL).

  4. Tiny "Nanoflares" Might Heat The Sun's Corona
    10/16/2014

    Today, a team led by Paola Testa of the Harvard-Smithsonian Center for Astrophysics (CfA) is presenting new clues to the mystery of coronal heating using observations from the recently launched Interface Region Imaging Spectrograph (IRIS). The team finds that miniature solar flares called "nanoflares" - and the speedy electrons they produce - might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.

  5. Optics And Photonics Technology Leaders, Researchers And Companies To Convene At OSA’s Annual Meeting, Frontiers In Optics 2014
    10/16/2014

    Innovations from more than 600 scientific, technical and educational presentations will be highlighted during The Optical Society’s (OSA) 98th Annual Meeting, Frontiers in Optics (FiO) 2014, being held Oct. 19 - 23 in Tucson, Arizona, USA.

  6. Integrated Circuits With Silicon Hybrid Plasmonic Waveguides
    10/16/2014

    Traditional designs for silicon (Si) photonics often use a metal strip, placed above thick upper-cladding on top of a Si core, as a micro-heater. Such designs, however, have low heating efficiencies, slow responses, and small thermal dynamic ranges.

  7. Making Mass Spectroscopy Mobile
    10/16/2014

    Using a new sampling technique combined with a portable mass spectrometer, Purdue University researchers have created a miniaturized lab. A long list of tests can now be run rapidly without conventional sample preparation methods.

  8. U.S. Navy Awards Raytheon $49.5M Enhanced Laser Maverick Production Contract
    10/16/2014

    The U.S. Navy has awarded Raytheon Company (NYSE: RTN) a $49.5 million contract for production of new laser-guided Maverick missiles (AGM-65E2/L).

  9. Light Bending Material Facilitates The Search For New Particles
    10/16/2014

    Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers at Chalmers University of Technology have designed a material that makes it much easier to distinguish the particles.

  10. Magnetic Mirrors Enable New Technologies By Reflecting Light In Uncanny Ways
    10/16/2014

    As in Alice’s journey through the looking-glass to Wonderland, mirrors in the real world can sometimes behave in surprising and unexpected ways, including a new class of mirror that works like no other.
