YOKOHAMA, Japan, May 30, 2013 — A light-sensitive resin that responds to the process of “carbonizing,” or charring, could provide scientists with a new material that can be molded into complex, highly conductive 3-D structures with features just a few microns across. The findings...
Light Coupled in Fiber Oscillates Longitudinally
VIENNA, May 29, 2013 — Lightwaves, which typically oscillate perpendicular to their propagation direction, have been seen oscillating longitudinally when coupled into glass fibers, suggesting that light and matter couple much more strongly than previously thought.
Cradle Turns Smartphone into Biosensor
CHAMPAIGN, Ill., May 28, 2013 — A unique cradle and app for the iPhone use the phone’s own camera and processing power to create a handheld biosensor capable of detecting any kind of biological molecules or cells.
Old Imaging Technique Gets Quality Boost
PERTH, Australia, May 28, 2013 — Targeting crosstalk problems — visible ghostlike shadows in 3-D images — could significantly increase the quality of a widely used century-old printing technique, new research out of Australia suggests.
University of Eastern Finland Opens Photonics Institute
JOENSUU, Finland, May 28, 2013 — A new Institute of Photonics launched at the Faculty of Science and Forestry of the University of Eastern Finland aims to enhance education and research in photonics and to promote international collaboration in the field.

ANN ARBOR, Mich., May 24, 2013 — A baby boy can now breathe easy thanks to a 3-D-printed tracheal splint implant developed at the University of Michigan.
Spray-On Flat Lens Works in the UV
GAITHERSBURG, Md., May 24, 2013 — A metamaterial-based flat lens that’s easy to fabricate and that can bend and focus UV light could improve photolithography, nanoscale manipulation and manufacturing, and even high-resolution 3-D imaging, say scientists at the National...
IEEE Offers Open-Access Option for All Peer-Reviewed Journals
PISCATAWAY, N.J., May 23, 2013 — Driven by member and author feedback, technical professional association IEEE has announced that all of its peer-reviewed journals — more than 100 — now offer open-access publishing options.
Method Creates Atomic-Scale Semiconductors
RALEIGH, N.C., May 23, 2013 — An inexpensive material that can be “grown” in layers only one atom thick has yielded atomic-scale semiconductor thin films. The technique could be applied to make these devices wide enough to coat wafers that are 2 in. wide or larger.
Photonics Societies Launch National Initiative
WASHINGTON, May 23, 2013 — The National Photonics Initiative — an alliance seeking to unite experts from industry, academia and the government to advance photonics R&D, to grow the US economy, and to improve national security — officially launched today.
Transparent Electrode Key to Flexible Solar Cells
WEST LAFAYETTE, Ind., May 23, 2013 — A hybrid transparent electrode that overcomes the “electron-transport bottleneck” of thin films could pave the way for flexible solar cells and color monitors, head-up displays in car windshields and optoelectronics circuits for sensors and...
Controlling Light … with Light
HOUSTON, May 22, 2013 — Gold nanoparticles arranged into geometric patterns can control incoming light with light via a four-wave mixing process, transforming its output into a different color, Rice University theoretical and applied physicists say. The technique could be...
Nanoantennas Improve Infrared Sensing
PHILADELPHIA, May 21, 2013 — Patterning nanoantennas with “slots” that correspond to wavelengths in the mid-IR has yielded a new way to tune IR light into mechanical action, paving the way for more sensitive IR cameras and more compact chemical-analysis techniques....
Optical Chip Innovation Transferred to Industry
SYDNEY, May 21, 2013 — An optics innovation that enables researchers to vary how light is split on optical chips has been transferred from the University of Sydney to Finisar, creating a wave of sales for the Waterloo, Australia-based company.
Wheels Come Off Planet-Hunting Telescope
MOFFETT FIELD, Calif., May 20, 2013 — The Kepler space telescope, NASA’s primary instrument for detecting planets beyond our solar system, suffered a critical failure last week when one of its four reaction wheels stopped functioning, the agency announced. The malfunction leaves just...
Optogenetic Tool Has Potential for Brain Mapping
ARLINGTON, Texas, May 17, 2013 — An optogenetic tool that can map and track interactions between neurons inside different areas of the brain using low-energy near-infrared (NIR) light could help scientists better understand how different parts of the brain react when a linked area...
Alloys So Bright They Could Have Medical Apps
PITTSBURGH, May 16, 2013 — Nanoscale alloys that are 100 times brighter than those currently being used could have potential applications in medicine, demonstrations conducted at the University of Pittsburgh (Pitt) have shown.
Electronic Components Speed Spectroscopy
GAITHERSBURG, Md., May 16, 2013 — A new solution employing electronic components could make atmospheric-gas measurement more even and 1000 times faster than with conventional techniques and could advance greenhouse-gas measurement.
Polariton Laser Is Electrically Injected
STANFORD, Calif., and WÜRZBURG, Germany, May 16, 2013 — A paradigm-shifting “polariton” laser fueled by electricity rather than by light has been demonstrated by researchers at the University of Michigan.
Composite Created with Specific Optical Properties
DONOSTIA, Spain, May 15, 2013 — When it comes to creating nanostructured composite materials with specific optical and electrical properties, size matters.
