Earth’s UV Signature Revealed
BOULDER, Colo., Jan. 19, 2010 – On its way to rendezvous with a comet, the spacecraft Rosetta turned an eye toward Earth and recorded its ultraviolet signature. The information it collected may help astrobiologis...
Mirrors Replace Lenses in UAVs
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,...
Insectlike Night Cameras
LUND, Sweden, Jan. 11, 2010 – A collaboration between biologists and mathematicians at Lund University in Sweden and car maker Toyota aims to develop a new type of color camera inspired by the nocturnal vision of insects to help people drive cars more safely at night. The...
LHC Records 1M Collisions
AMES, Iowa, Jan. 7, 2009 – Three Iowa State University physicists who took winter trips to the Large Hadron Collider for meetings and experimental work are starting to see real data from the planet’s biggest science experiment – finally. The multibillion-dollar collider made...
Light Silences Brain Cells
CAMBRIDGE, Mass., Jan. 6, 2010 – Neuroscientists at MIT developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, such tools could lead to new treatments for the abnormal activity associated...
Single Cycle of Light Pulsed
KONSTANZ, Germany, Jan. 6, 2010 -- Extremely short laser pulses – the duration of only one cycle of light – have been generated at the 1.5-µm wavelength used to transmit data, an achievement that could benefit frequency metrology and the ultrafast sciences such as ultrafast optical...
‘GRIN on steroids’: New lens uses opaque metamaterials
DURHAM, N.C. – It doesn’t look like a lens; it looks more like a tiny set of Venetian blinds. It’s not even made of traditional lens materials such as highly polished glass or plastic. But a new generation of lenses has the potential to make big changes in radar...
A backward shock wave comes forward
HANGZHOU, China – A group of researchers has demonstrated a reverse photonic shock wave. As a result, high-energy physics could have a new particle detector, and proposed invisibility cloaks already...
Artificial vacuums unleash speed of quantum computing
TORONTO – Instilling photonic crystals with the occasional quantum dot triggers a vacuumlike effect that alters light in such a way that may make ultrafast optical computing possible. Sajeev John of the University of Toronto and his student Xun Ma were...
Creating nanostructures with shadows
BERKELEY, Calif. – From out of the shadows, researchers at the University of California, Berkeley, have built nanostructures that might lead to more efficient solar power. Another potential applicati...
Europe signs on to big x-ray facility
HAMBURG, Germany – Europe soon will boast a multimillion-dollar research facility that promises to open up completely new research opportunities for scientists and industrialists alike. The European X-ray Free Electron Laser (European XFEL), which will be located in...
Filming photons using electrons
PASADENA, Calif. – A new technique that tracks and images nanoscale matter in real time also enables researchers to image electrical fields produced by the interaction of electrons and photons. The method, which uses four-dimensional microscopy, was developed by...
Isolating hot spots enhances Raman results
CAMBRIDGE, Mass. – A new technique demonstrated by a Harvard group may provide environmental researchers, chemists and forensic investigators with a new tool to detect and identify trace molecules. The research combined the two separate concepts of...
Optical microrings boost cancer detection
URBANA-CHAMPAIGN, Ill. – Sensitive detection of biomolecules is of great interest for applications such as drug development, virus detection, environmental monitoring and medical diagnostics. In contrast to optical biosensors based on surface plasmon resonance,...
Partnership to advance genetic sequencing
Jan 4, 2010 — Biotechnology company Life Technologies Corp. of Carlsbad, Calif., and febit holding GmbH of Heidelberg, Germany, a genomic research provider, have announced their intention to collaborate. They will combine the former company’s Applied Biosystems...
Protecting aircraft from lasers
LA JOLLA, Calif. – During the operation of astronomical telescopes, laser beams frequently are emitted into the atmosphere for satellite or lunar ranging. They also can be used to create artificial g...
Pushing light to new limits
ADELAIDE, Australia – Australian researchers are rewriting the rules on how light behaves when confined in ever-smaller optical fibers. Everything has its limits, and light-carrying optical fibers are no exception. Until now, it was thought that, as the size of the...
