Research & Technology News
On-Chip Light Speeds up Computing
SYDNEY, Australia, Feb. 1, 2010 – A new laser that allows light to be used on a computer chip has been realized by an international team of researchers, led by David Moss, associate professor and senior researcher at The University of Sydney. The group developed a multiple wavelength laser on a silicon chip that produces light to process and transmit information, and in doing so, will speed up computing. "The on-chip light source will be key to enabling the simultaneous transmission of multiple data channels either...

Faster-Than-Light Photons
GAITHERSBURG, Md., Jan. 27, 2010 – By adding a single, strategically placed layer, a group of researchers sped up photons to seemingly faster-than-light speeds through a stack of materials. This experimental demonstration confirmed intriguing quantum-physics predictions that...
Gecko Grip Given to Any Surface
HOUSTON, Jan. 27, 2010 – A graduate student at Rice University has devised a way to transfer the gravity-defying grip of a gecko – so strong it can stick to even glass – from any surface to anoth...
Lidar Images Haiti Disaster
ROCHESTER, N.Y., Jan. 26, 2010 – In the aftermath of the Jan. 12 earthquake that struck Haiti’s capital, Port-au-Prince, scientists from Rochester Institute of Technology (RIT) are sweeping the leveled city with h...
How ‘Random’ Lasers Work
SALT LAKE CITY, Jan. 25, 2010 – When University of Utah scientists discovered a new kind of laser that was generated by an electrically conducting plastic or polymer, no one could explain how it worked, and some d...
Sensor Creates Glucose Breathalyzer
GAINESVILLE, Fla., Jan. 25, 2010 – A new biomedical sensor could provide fresh, inexpensive diagnosis and treatment methods for people suffering from a variety of diseases. University of Florida engineers have d...
X-rays Could Improve Grain
HARPENDON, England, Jan. 25, 2010 -- Pioneering research combining plant breeding and high-intensity synchrotron x-rays is being used to explore the possibility of creating a healthier, more mineral-rich flour. Sc...
Defect-free Thin Films Realized
ITHICA, NY, Jan. 22, 2010 – To make thin films for semiconductors in electronic devices, layers of atoms must be grown in neat, crystalline sheets. But while some materials grow smooth crystals, others tend t...
Opnext Hires Head of Investor Relations
FREMONT, Calif., Jan. 22, 2010 – Opnext Inc., an optical modules, components and subsystems manufacturer, has announced that Steve Pavlovich has joined the company as its vice president of investor relations. Pavl...
Blue/Violet Light Aid Ozone Detectors
FREIBURG, Germany, Jan. 21, 2010 – A highly sensitive, miniaturized chemical sensor that takes advantage of blue- to violet-wavelengths of light has been developed to detect ozone levels. Created at the Fraunhofer I...
Light Kills Germs
Urbana-Champaign, Ill. Jan. 21, 2010 - In the battle against bacteria, researchers at the University of Illinois are using visible light to destroy harmful bacteria and viruses, even in the dark. Based upon a new ca...
UV LED Reduces Epileptic Seizures
MINNEAPOLIS, Jan. 21, 2010 - UV LED therapy tested on rats with epilepsy shows promise as a technique for preventing focal seizures in humans. Researchers from the University of Minnesota Medical School, l...
Epitaxic Graphene Demonstrated
MIDDLESEX, England, Jan. 20, 2010 – A collaborative research project has brought the world a step closer to producing a new material on which future nanotechnology could be based. Researchers across Europe, including...
Mini ‘Scope May Aid Cancer Surgery
PHILADELPHIA, Jan. 20, 2010 – A new, in vivo microscopic imaging technology has led to the development of a technique that may help improve outcomes of surgery to remove pancreatic cancer. The technique was the result of work performed by the INSERM research group at the...

DRESDEN, Germany, Jan. 19, 2010 – Unmanned aerial vehicles (UAVs) carry optical measuring equipment that is required to operate free of chromatic aberrations across a wide spectral range – from ultraviolet to infra...
Light Tied in Knots
BRISTOL, GLASGOW & SOUTHAMPTON, UK, Jan. 18, 2010 -- A branch of abstract mathematics inspired by knots that occur in shoelaces and rope has been used to design holograms capable of creating knots in optical vortices.
Exoplanet's Spectrum Revealed
MUNICH, Germany, Jan. 13, 2010 – By studying a triple planetary system that resembles a scaled-up version of our sun’s family of planets, astronomers have obtained the first direct spectrum of a planet orbiting a distant star, a milestone in the search for life elsewhere in...
Photonic Chip Holds World Map
GHENT, Belgium, Jan. 13, 2010 -- Using high-resolution optical lithography techniques important in microelectronics fabrication, researchers in Belgium produced a terascale world map with a circumference of only 40 µm, or about half the width of a human hair.
THz Laser Tuning Detects Substances at Airports – and Elsewhere
Jan 13, 2010 — Detecting dangerous materials at airports is a high security priority, and the Christmas Day events in an airplane over Detroit served to put a new spotlight on materials detection. One challenge for current techniques is that they cannot always...
QCLs: More Light, Less Heat
EVANSTON, Ill., Jan. 12, 2010 – Northwestern University researchers developed compact, mid-infrared laser diodes that generate more light than heat – a breakthrough in quantum cascade laser (QCL) efficiency and an important step toward use of QCLs in a variety of applications,...
