Surprising Quantum Source Yields Info Advantage
SINGAPORE, Aug. 13, 2012 — Quantum entanglement may not always be necessary to run quantum computers, new research suggests. Moreover, technologies discovered over the past few years can gain a quantum advantage without entanglement.
For New Applications, Give Photonic Fiber a Twist
ERLANGEN, Germany, Aug. 10, 2012 — Simple longitudinal twists that convert photonic crystal fibers into filters were measured and theorized upon; the results suggest new applications in optical communications and will enable the construction of sensors, light amplifiers and lasers.
Sound Waves Focused Like A Camera Lens
UNIVERSITY PARK, Pa., Aug. 10, 2012 — A metamaterial capable for the first time of manipulating a variety of acoustic waves with one simple device was designed and computationally tested. The device holds promise for applications across various acoustic fields, from medical ultrasound...
System Simultaneously Uses Loss, Gain
ERLANGEN, Germany, Aug. 10, 2012 — Light absorption (loss), usually seen as a disadvantage in optical metamaterials, has been shown to have useful applications.
Process Could Make IR Lenses up to 70 Percent Cheaper
FREIBURG, Germany, Aug. 8, 2012, — A new fabrication process that lowers the cost of infrared lenses for thermal cameras by 70 percent could make such devices more attractive for integration into cars as driver warning systems.
EssentOptics Expands into Asia, Europe
MINSK, Belarus, Aug. 7, 2012 — The optical monitoring systems and spectrophotometers manufacturer is expanding its international presence into Asia and Europe through distribution agreements with Indeco Inc. of Tokyo and VW-TIM of Jena, Germany.
Toward an ‘Unbreakable’ Message Exchange
WÜRZBURG, Germany, Aug. 6, 2012 — Single particles of light were produced and implemented into a quantum key distribution link, paving the way for unbreakable communication networks.
Leoni Acquires Richard Losch Inc.
NUREMBERG, Germany, Aug. 5, 2012 — To strengthen its position in the field of fiber optics, Leoni Fiber Optics GmbH has announced its acquisition of all the assets of Richard Losch Inc. of Bend, Ore.

Are you positioned for success?
Aug 1, 2012 — The one thing that is never far from our thoughts these days is the economy and, closer to home for many of us, the state of the jobs market. The latest US jobs report told the grim story of only 80,000 jobs added in June, far below the number...
Astronomers decry UK’s defunding of Hawaii telescopes
HARWELL, UK — May 31 was “a sad day for British astronomy,” according to David Southwood, president of the Royal Astronomical Society (RAS). That was the day the Science and Technologies Facilities Council (STFC) announced that it would close —...
Controlled Beam of Single Photons Produced
CAMBRIDGE, Mass., Aug. 1, 2012 — Quantum computing is expected to surpass conventional computing in terms of speed and performance of complex computations. However, the development of quantum devices for real-world applications has been met with major challenges.
Desai Joins Kotura Team

Gigapixel “supercamera” delivers sharp shots
DURHAM, N.C. – The challenge to creating high-pixel imaging lies in the sophistication of the integrated circuits rather than the optics, and now scientists have overcome this hurdle by developing a supercamera that synchronizes 98 microcameras into a single...
LightPath Hires Hayden IR
Aug 1, 2012 — Optical components manufacturer LightPath Technologies Inc. of Orlando, Fla., has retained Hayden IR to develop and implement a strategic investor relations program to raise its visibility and to strengthen its relationship with the investment...
Matter waves conjured in Schrödinger’s hat
SEATTLE – An amplifier devised to boost light, sound or other waves while hiding them inside an invisible container could lead to the construction of a quantum microscope that captures quantum waves and monitors electronic processes on computer chips. The...
Nanoantenna Made of DNA Captures, Emits Light
PARIS, Aug. 1, 2012 — A bio-inspired light nanoantenna has been created using two gold nanoparticles, short DNA strands and a tiny fluorescent molecule that can capture and emit light. The discovery paves the way toward the development of highly efficient LEDs and...
Nondistorting mirror eliminates blind spots
PHILADELPHIA – Have you ever been passed on the road by a vehicle that seems to have come out of nowhere? Well, drivers: Take heed. A new subtly curved side mirror that dramatically increases the field of view with minimal distortion could offer an alternative to...
