Research & Technology News
Microscale Optical Accelerometer Engineered
PASADENA, Calif., Oct. 24, 2012 — An ultrasensitive, miniature optical accelerometer uses laser light rather than electrical circuits to gauge movement, a change that could transform the microelectronics industry, its creators say.
Most Advanced Giant Telescope Mirror Completed
TUCSON, Ariz., Oct. 24, 2012 — The most challenging astronomical mirror ever made — 10 times more powerful than any other large mirror — was completed for a giant telescope that will explore star formation, black holes and planets in the early universe.
Fishy Felon Breaks a Law of Physics
BRISTOL, England, Oct. 23, 2012 — A multilayer crystalline structure used by silvery fish to evade ocean predators bends the laws of physics and could be the key to developing better optical devices.
Superparticles Shaped from Nanorods
GAINESVILLE, Fla., Oct. 23, 2012 — A new technique for growing complex superparticles from self-assembling nanorods could create a new generation of polarized LEDs.
Atom Optics Comes of Age
GREENBELT, Md., Oct. 19, 2012 — NASA is funding atom interferometry, a variation on the 200-year-old optical technique, in the belief that the emerging, highly precise measurement technology will allow the detection of ripples in space-time and other events.
OSA: Attendance Up at Frontiers in Optics 2012
ROCHESTER, N.Y., Oct. 19, 2012 — Frontiers in Optics 2012, the Optical Society’s (OSA) 96th annual meeting, attracted more than 1700 attendees — a significant increase over last year, the society reported Friday. The five-day event, which is collocated with the American...
Training Light to Cool Materials
BETHLEHEM, Pa., Oct. 19, 2012 — By exploiting the resonance behaviors of opposing light-scattering phenomena, photons may one day be used to cool the materials through which they pass, rather than heating them. The breakthrough could lead to smaller, lighter and cheaper...
Optical Vortex Beams Emit on Silicon
BRISTOL, England, Oct. 18, 2012 — The smallest emitter of orbital angular momentum (OAM) light — light that travels in a twisting, corkscrew-like manner — was created on silicon. The chip is one thousand times smaller than any other such device reported to date and could be used in...
Material Could Provide Self-Cleaning, Waterproof Optics
PHILADELPHIA, Oct. 17, 2012 — Inspired by butterfly wings, a new material that repels water and shines with beautiful, brilliant hues could provide the foundation for optical devices that are self-cleaning and waterproof.
Organic Solar Cell Could Recharge Electronics on the Move
COVENTRY, England, Oct. 17, 2012 — Coping with a dead cell phone while you’re on the go could become yesterday’s problem, thanks to a new organic photovoltaic solar cell that could recharge a standard lithium-ion battery, even in low-light conditions.
Photonic Crystal Fiber Inventor Named OSA VP
ROCHESTER, N.Y., Oct. 17, 2012 — Photonic crystal fiber inventor Philip Russell was elected as The Optical Society’s 2013 vice president, the organization announced Tuesday at Frontiers in Optics 2012. Three directors at large were also chosen by OSA members.
Silk’s Photonic Talents Brought to Light at FiO 2012
ROCHESTER, N.Y., Oct. 17, 2012 — Natural silk's potential as an eco-friendly way to manipulate light for applications such as biosensors, lasers and photonic chips was presented by US and French researchers this week at the Optical Society's 96th annual meeting, Frontiers in Optics...
Anti-Laser Eyewear Filters Multiple Wavelengths
PORTON DOWN, England, Oct. 16, 2012 — Eyewear that blocks a variety of wavelengths to protect pilots against different types of lasers shined into cockpits is now being tested by Britain’s Ministry of Defense.
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...
