Spectroscopy Technique Advances Spintronics
BERKELEY, Calif., Oct. 16, 2012 — An x-ray spectroscopy technique marks a significant step toward removing a major roadblock impeding the use of certain semiconductors in computing, because processing data using electron “spin” rather than charge would mean smaller, faster and more...
Ultrafast Laser Reveals Molecular Mysteries
TUCSON, Ariz., Oct. 16, 2012 — Eadweard Muybridge used high-speed photography to determine whether a galloping horse touches the ground at all times (it doesn’t). Now, 134 years later, University of Arizona physicists used ultrafast, high-energy laser pulses to solve a similar...
Aachen Wins Funding for Digital Photonic Production Center
AACHEN, Germany, Oct. 15, 2012 — The Digital Photonic Production cluster is one of two at RWTH Aachen University that will receive government funding under a public-private partnership initiative to foster innovation.
Concentrated Sunlight Earns Environmental Award
FREIBURG, Germany, Oct. 15, 2012 — A multijunction solar cell-based concentrator photovoltaic system that captures nearly all of the sun’s energy is one of two photovoltaic technologies to win a national environmental award.
Ultrathin Coatings Exploit Optical Phenomenon
CAMBRIDGE, Mass., Oct. 15, 2012 — By exploiting an overlooked optical phenomenon, ultrathin metal surfaces were made to shine vibrant hues. The coatings that change color with only a few atoms’ difference in thickness could provide new possibilities for sophisticated optical...
Improving Nanoscale Manufacturing with IR Spectroscopy
URBANA, Ill., Oct. 12, 2012 — A new infrared spectroscopy diagnostic tool that can chemically analyze polymer lines as small as 100 nm could be the answer to the industry’s critical need for nanomanufacturing chemical metrology, according to an industry-university collaboration.
Plasmonics Promising for Optically Induced Electronics
HOUSTON, Oct. 12, 2012 — Nanoscale plasmonic antennas, or nonamers, attached to graphene could theoretically create on-demand electronic circuits by hitting them with light at particular frequencies.
Solar Uses Blossom for ‘Nanoflowers’
RALEIGH, N.C., Oct. 12, 2012 — Those with even a passing interest in flowers are familiar with geraniums, but how about germaniums? Flowerlike structures with an enormous surface area crafted from germanium sulfide (GeS) &mdash a semiconductor material — hold promise...
Laser Pointer IDs Dangerous Chemicals
BEERSHEVA, Israel, Oct. 11, 2012 — A new portable Raman spectrometer created using an ordinary green laser pointer can detect minute traces of explosives and other hazardous chemicals in real time.
Photonic Gel a Metamaterial with Myriad Uses
HOUSTON and CAMBRIDGE, Mass., Oct. 11, 2012 — Thin films that change color under certain conditions and are incredibly cheap to make may inform future multiband optical elements in laser-driven systems or high-contrast displays, among other applications.
OCT Images Blood Vessels that Feed Cancer
VIENNA and MUNICH, Oct. 9, 2012 — An optical coherence tomography technique that noninvasively maps the network of tiny blood vessels in the epidermis could soon help doctors better diagnose, monitor and treat skin cancer.
Quantum Optics Work Wins Physics Nobel
STOCKHOLM, Oct. 9, 2012 — Separate but related quantum optics technologies — ions in a harmonic trap and photons in a cavity — that allow the measurement and control of individual quantum systems were recognized Tuesday by the Royal Swedish Academy of Sciences...
Laser Reveals Surprising Optical Effect on Ferromagnets
HAMBURG, Germany, Oct. 5, 2012 — Investigations of magnetism using a free-electron laser unveiled a new mechanism that causes ferromagnetic materials to demagnetize. The finding — previously theorized, but never before observed &dmash; could play a role in reducing the size of...
Light Tube Grabs, Scans Tiniest Bacterium
FREIBURG, Germany, Oct. 5, 2012 — A light tube that can grab, orient and record the movements of tiny agile unicellular organisms may soon help scientists better understand bacterial infectious diseases.
Photocurrent of Single Molecule Measured
MUNICH, Oct. 4, 2012 — Single small molecules can be used as functional components in optoelectronic circuits, but until now, controlling and probing such molecules for photovoltaic and photoelectrochemical applications has proved difficult.
Quantum Mechanics Could Thwart Counterfeiters
GARCHING, Germany, CAMBRIDGE, Mass., and PASADENA, Calif., Oct. 4, 2012 — Physicists in Germany and the US want to take a principle from nature — that information stored on a quantum bit, or qubit, cannot be cloned — and apply it to the problem of credit card fraud.
3-D Camera Studied for Space Mission
TRONDHEIM, Norway, Oct. 3, 2012 — An international collaboration of space agencies aims to improve cameras for future missions by adding a third dimension.
All-Optical Amplification of Signals
MINNEAPOLIS/ST. PAUL, Oct. 3, 2012 — The discovery that the force of light in a nanoscale switch is strong enough to move an optical waveguide without having to rely on the device’s mechanical structure could dramatically increase Internet download speeds while also consuming...
Optical Physicist Wins ‘Genius Grant’
TUCSON, Ariz., Oct. 2, 2012 — A physicist who developed a breakthrough imaging technique for finding Earth-like planets outside our solar system is among 23 new MacArthur Fellows for 2012. As with all the other winners, University of Arizona astronomer and optical physicist...
Solar Efficiency of Black Silicon Doubled
BERLIN, Oct. 2, 2012 — A solar material that takes advantage of a spectrum totally unused by standard cells could be the key to more efficient photovoltaics, now that a team in Germany has successfully doubled its efficiency.
Cost-effective infrared lenses produced
FREIBURG, Germany – Once the process is refined enough to make mass production cost-effective, the microbolometers could become practical for application such as production process monitoring, warning systems and energy audits. A new fabrication process that its...
Diamond sharpens x-ray beam razor thin
MENLO PARK, Calif. – A thin sliver of diamond can transform the Linac Coherent Light Source (LCLS) into a precise tool for studying and manipulating matter at the atomic level – and may enable experiments never before possible. In the “self-seeding”...
