Nondistorting Mirror Receives Patent
PHILADELPHIA, June 8, 2012 — A subtly curved side mirror that eliminates dangerous blind spots for drivers has been patented.
Smallest Possible Five-Ringed Structure Created
LONDON, June 7, 2012 — In honor of the upcoming Summer Olympics, the smallest possible five-ringed structure – just 1.2 nm in width and about 100,000 times thinner than a human hair – has been created and imaged using a combination of synthetic chemistry and...
Tabletop Device Creates All Wavelengths in 1 Beam
ARLINGTON, Va., June 7, 2012 — More than 5000 low-energy photons have been converted into one high-energy x-ray photon. The coherent, directed light beam was generated for the first time using a device small enough to fit on a single laboratory table.
Exotic Particles, Chilled and Trapped, Form Giant Matter Wave
SAN DIEGO, June 6, 2012 — Excitons were trapped and cooled so effectively that they condensed and cohered to form a giant matter wave, a feat that will enable scientists to study the physical properties of excitons, which exist only fleetingly yet offer promising...
2013 Prism Awards Open for Entries
PITTSFIELD, Mass. – Photonics industry heavyweights and budding spinoffs alike are poised to compete for this year’s Prism Awards for Photonics Innovation. Dubbed the “Oscars of Photonics,” the Prism Awards is an international competition that...
From Embryo to Larva: Microscope Observes Fly Growth
HEIDELBERG, Germany, June 5, 2012 — For the first time, a two-and-a-half-hour-old fruit fly embryo was filmed in 3 D using a new microscope that rapidly images biological processes in thick samples at unprecedented detail.
FEL Reveals Detailed Architecture of Proteins
HAMBURG, Germany, June 4, 2012 — A novel free-electron laser (FEL) x-ray technique that obtains high-resolution structural insight into biomolecules can deliver structural data that could be used to design tailor-made medications.
Laser ARPES Helps Explain Superconductivity
BERKELEY, Calif., June 4, 2012 — A new ultrafast laser angle-resolved photoemission spectroscopy (ARPES) technique may soon help scientists realize some of the biggest obstacles to the electronic states of high-temperatures superconductors so that they may one day put these...
Planet-Hunting with Laser Rulers
GARCHING, Germany, June 1, 2012 — Astronomers searching for extrasolar planets may be a step closer to finding other Earthlike places in the universe around sunlike stars, thanks to a new tool that promises to increase the accuracy of planet-hunting devices by tenfold.
Cold atoms in an optical lattice simulate graphene
ZURICH – The creation of a tunable system of ultracold atoms within a honeycomblike structure similar to that found in graphene may help identify the electronic properties of materials that have yet to be discovered. Professor Tilman Esslinger of the...
Elementary quantum network realized
GARCHING, Germany – Two single-atom nodes have been used to send, receive and store quantum information using photons, a quantum information-sharing milestone. “We have realized the first prototype of a quantum network,” said Dr. Stephan Ritter of Max...
Fraunhofer Opening Laser Research Center at Strathclyde
GLASGOW, Scotland, June 1, 2012 — The UK’s first Fraunhofer Center will be based at the University of Strathclyde, the university announced this week. The new Fraunhofer Centre for Applied Photonics will be a hub for industry-driven laser research and technology for health...
Laser built on a silicon chip
SINGAPORE – A laser with a novel micro-loop mirror design fabricated on a silicon chip uses III-V semiconductor materials – a step forward for high-speed optical communications and interconnects on electronic chips. Active optical fibers with silicon...
Laser mixing generates multifrequency light
SANTA BARBARA, Calif. – A groundbreaking laser mixing technique can manipulate electron-hole collisions to create many frequencies of light simultaneously. This mechanism for ultrafast light modulation has potential applications in high-speed optical communications. ...
Lasers find distant hidden explosives
VIENNA – A new method of Raman spectroscopy uses laser light to detect chemicals inside a container from a distance of more than 100 m. Laser light is scattered in a very specific way by various substances. This is the basis of Raman spectroscopy and can be...
Many-body system beats computer in simulating quantum dynamics
MUNICH – A recent experiment has shown that a many-body system of ultracold atoms can be used as a quantum simulator for experiments where classical computers fail. This also allows physicists to have a better understanding of how particles tunnel, and it...
OCT Device Could KO Ear Infections
CHAMPAIGN, Ill., June 1, 2012 — A new optical coherence tomography (OCT) device that can see difficult-to-detect bacteria behind the eardrum could help clinicians to better diagnose and treat chronic ear infections.
Plasmonic material bridges photonics, electronics gap
WEST LAFAYETTE, Ind. – A thin film of titanium nitride was coaxed into transporting plasmons, becoming the first nonmetal to be added to the short list of surface-plasmon-supporting materials and bridging the gap between photonics and electronics. The nonmetal could pave...
Superradiant laser holds bright promise
BOULDER, Colo. – A new “superradiant” laser that traps 1 million rubidium atoms into a 2-cm space between two mirrors produces a deep-red laser beam that could boost the performance of the most advanced atomic clocks, communications and navigation...
Thermal cloak hides heat
PARIS – In a new approach to invisibility cloaking, French researchers propose isolating or cloaking objects from sources of heat – essentially “thermal cloaking.” The method, developed by Sebastien Guenneau and his colleagues at Centre...
UK’s Defunding of Hawaii Telescopes Decried
HARWELL OXFORD, England, June 1, 2012 — Thursday was "a sad day for British astronomy," according to the president of the Royal Astronomical Society. That was the day the UK’s Science and Technologies Facilities Council (STFC) announced it would close — or transfer to other...
Matter Waves Conjured in Schrödinger’s Hat
SEATTLE, May 31, 2012 — 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.
Short Movies Stored in Atomic Vapor
COLLEGE PARK, Md., May 31, 2012 — Using lasers and a magnetic field, physicists stored and replayed two letters of the alphabet in a tiny cell of rubidium atoms, the first time two images have been reliably stored in a nonsolid medium.
Tabletop Laser Precisely Cuts Brain Tissue
BERLIN, May 30, 2012 — A new tabletop solid-state laser system that produces 6.45-µm pulses to precisely cut brain tissue was developed as part of an interdisciplinary European Union project involving partners from seven European countries.
GFPs Measure Intracellular Heat
BARCELONA, Spain, May 29, 2012 — A quicker, more precise method that measures internal cell temperatures noninvasively using green fluorescent proteins (GFPs) could help scientists to learn more about cellular processes and to distinguish healthy cells from cancerous ones.
