Single-Photon Project Launched
MILAN, Aug. 2, 2010 — “MISPIA” (Microelectronic Single-Photon 3-D Imaging Arrays for low-light high-speed safety and security applications) is a new collaborative research project funded by the European Commission in its Seventh Framework Programme for research, technological development and demonstration activities (2007-2013). The program was launched in June under the coordination of the Polytechnic of Milan, Electronics and Information Department. According to the grant agreement (#257646) signed...
Building with optical Legos
HOUSTON – Just as generations of children have enjoyed stacking and building with plastic Lego toys, scientists are now using light-activated nanoshells as Lego-like building blocks for both 2- and 3-D structures that could be used in chemical sensors,...
Listen hard, and you’ll hear the NEXT BIG THING coming!
Aug 1, 2010 — It’s still quite young, but the 21st century has yet to produce a truly life-changing technology. Certainly the 20th century did, with the advent of lasers and transistors and all of the tools and toys they have inspired and enabled since...
Nanoscale gold boosts infrared detection
TROY, N.Y. – For the past decade, state-of-the-art infrared photodetectors have been based on MCT, or mercury cadmium telluride, technology, which offers strong signal sensing but is associated with various drawbacks, such as its suboptimal signal-to-noise ratio...
Optical gain in plasmonic waveguides opens door to subwavelength applications
REYKJAVIK, Iceland – Researchers at the University of Iceland, in collaboration with colleagues at Germany’s University of Cologne and Fraunhofer Institute for Applied Optics and Precision Engineering in Jena, have demonstrated amplified propagation of light in...
Rationally designing plasmonic devices using imaging and simulation
CÓRDOBA, Argentina, and CAMBRIDGE, UK – Researchers intent on building plasmonic sensors to a set of specifications now have a new tool to help in that quest, according to a group of investigators. The team has demonstrated that electron tomography and electrodynamic simulations can...
Transistor laser breaks the law
CHAMPAIGN, Ill. – A three-port quantum well transistor laser developed by Milton Feng and Nick Holonyak Jr. at the University of Illinois at Urbana-Champaign is rewriting a major current law. Thanks to this device, the behavior of photons, electrons and...
Flir Captures 1st Dreamliner Flight
PORTLAND, Ore., July 29, 2010 — Thermal camera maker Flir Systems Inc. captured full high-definition infrared footage last week during the first public flight of Boeing's 787 Dreamliner at the Farnborough International Airshow in Farnborough, England. The video and images...
Laser-Triggered Nanoblasts Treat Cells
ATLANTA, Ga., July 29, 2010 — Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells. A field of human...
Lasers Pin Atoms in Order
INNSBRUCK, Austria, July 29, 2010 — A fundamental physical phenomena, whereby an arbitrarily weak perturbation causes atoms to build an organized structure from an initially unorganized one, has been demonstrated for the first time. Physicists can observe quantum mechanical phase...
Monster Technology — The ‘Frankencamera’
STANFORD, Calif., July 29, 2010 — It’s big and it ain’t pretty, but it’s an experimentation in computation photography that went so right. It’s a new programmable camera platform called “Frankencamera.” A Stanford University photography...
Si Data Connection with Integrated Lasers
SANTA CLARA, Calif., July 28, 2010 — Intel Corp. announced an important advance in the quest to use light beams instead of electrons as data carriers in computers: development of a research prototype representing the first silicon-based optical data connection with integrated lasers....
Laser Boosts Blu-ray Disc Storage to 1TB
TOKYO & SENDAI, Japan, July 27, 2010 — Sony Corp. and Tohoku University have developed an ultrafast blue-violet (405 nm) semiconductor laser with high-intensity optical pulses capable of using two-photon absorption. The laser's 100-W output is more than 100 times higher than that of...
Nanoparticles Intensify QDs’ Glow
UPTON, N.Y., July 27, 2010 — By linking individual semiconductor quantum dots with gold nanoparticles, scientists at Brookhaven National Laboratory have demonstrated the ability to enhance the intensity of light emitted by individual quantum dots by up to 20 times. According to...
Microring Resonator Traps Nanoparticles
CAMBRIDGE, Mass., July 26, 2010 — Harvard engineers are using a silicon-based circular resonator, or microring, to confine microparticles stably for up to several minutes. The advance could lead to the ability to direct, deliver and store nanoparticles and biomolecules on...
THz Technique is ‘All-Optical’
TROY, N.Y., July 26, 2010 — A team of Rensselaer Polytechnic Institute researchers has opened the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 m using terahertz (THz) wave technology. The new, all-optical system has...
Strathclyde Spinout to Make microLEDs
STRATHCLYDE, England, July 24, 2010 — The University of Strathclyde has secured a spinout deal to form a company working in the field of novel next-generation light source technology, which could open up a range of opportunities in multibillion-dollar applications, including...
Buckyballs in Space
WASHINGTON, July 23, 2010 — Astronomers using NASA’s Spitzer Space Telescope to analyze infrared light from a planetary nebula, have discovered spectral signatures of carbon molecules, known as "buckyballs," in space for the first time. Buckyballs are soccer-ball-shaped...
UChicago Commits $50M to GMT
CHICAGO, July 23, 2010 — The University of Chicago will provide millions of dollars to the Giant Magellan Telescope (GMT) project, joining an effort to build the world’s largest telescope. The GMT, to be built in Chile, is set to eclipse the image quality even of the...
Optical Probe Bridges Gender Gap
EVANSTON, Ill., July 22, 2010 — A team led by a Northwestern University biomedical engineer has found that combining novel optical technologies with a common colon cancer screening test may allow doctors to more accurately detect the presence of colon cancer, particularly in...
Physicists Confirm Born’s Rule
INNSBRUCK, Austria & WATERLOO, Ontario, Canada, July 22, 2010 — Using a single-photon source, Austrian and Canadian quantum physicists said they ruled out the existence of higher-order interferences experimentally and confirmed an axiom in quantum physics: Born’s rule.
