Strain ‘bridges’ move germanium closer to lasing
ZURICH – Germanium, a semiconductor with far greater light conduction possibilities than silicon, is a step closer to providing a foundation for the light-based computers of tomorrow, thanks to a European team working to make the material laser-compatible. Today’s electricity-dependent silicon-based computer chips – with their on-going need for ever-smaller and more densely packed transistors to meet processing power demands – are rapidly approaching the limits of Moore’s law i...

WASHINGTON, June 28, 2013 — Stephanie Laga, a senior at the California Institute of Technology, has been awarded the first Paul A. Bonenfant Memorial Scholarship by the OSA Foundation.
New Optical Fiber Puts a Twist on Data Transmission
LOS ANGELES and BOSTON, June 28, 2013 — The data capacity of single-mode optical fibers, while having increased by four orders of magnitude over the last 30 years, is rapidly reaching the limits imposed by the fiber’s nonlinear effects. But a bicoastal team has devised a new fiber optic...
New Photodetector Makes Do with Few Photons
COLLEGE PARK, Md., June 28, 2013 — Using a scheme based on quantum mechanics called unambiguous state discrimination (USD), the lowest error rate yet was achieved for a photodetector deciphering a four-fold phase encoding of information.
Solar Cells Get Skinny
CAMBRIDGE, Mass., June 27, 2013 — Atom-thick photovoltaic sheets — 20 to 50 times thinner than the skinniest solar cells made today — are pushing toward the ultimate power conversion possible from a material for solar power, packing hundreds of times more power per weight than...
Telescopic Contact Lens Helps AMD Patients See
SAN DIEGO, and LAUSANNE, Switzerland, June 27, 2013 — A slim, telescopic contact lens that switches between normal and magnified vision using liquid crystal eyeglasses could provide a relatively unobtrusive way to enhance the sight of patients with age-related macular degeneration (AMD).
Laser-Guided Codes Advance Single-Pixel THz Imaging
CHESTNUT HILL, Mass., June 26, 2013 — A single-pixel imaging method capable of tuning terahertz radiation using laser-guided codes can produce clear images in a matter of seconds.
Optics and Photonics Pioneer James Gordon Dies
RUMSON, N.J., June 26, 2013 — James P. Gordon, co-inventor of the maser and a seminal contributor to optics and quantum electronics, died June 21. He was 85.
Gold Probes Offer Insight into Cancer
GLASGOW, Scotland, June 25, 2013 — Gold nanoprobes paired with FRET microscopy could yield a new generation of biological imaging and sensing techniques capable of studying cancer cells in minute detail, measuring the effectiveness of medicines at subcellular levels and identifying...
New Research Facilities to Support EU Solar Tech
BRUSSELS and ISPRA, Italy, June 25, 2013 — New facilities were inaugurated yesterday at the European Solar Test Installation in Ispra to enable the reference laboratory to assess new and improved photovoltaic devices, to perform prenormative research and to help develop international...
Luxexcel Teams with Photonics Institute on 3-D Printing
GOES, Netherlands, June 24, 2013 — Luxexcel and the Institute of Photonics at the University of Eastern Finland (UEF) in Kuopio, Finland, have partnered to develop an improved platform for photonic 3-D printing.
Multiview 3-D Photography Simplified
CAMBRIDGE, Mass., June 24, 2013 — A small checkerboard patterned plastic film inserted beneath the lens of an ordinary camera can transform the device into a light-field camera capable of producing multiperspective images.
SERS, Nanoprobes Seek to Detect Infections Early
DURHAM, N.C., June 21, 2013 — Nanoprobes used in conjunction with surface-enhanced Raman scattering (SERS) can be used to reveal a specific molecular marker’s optical fingerprint. The work is a proof-of-principle approach to using light to detect infections before patients...
Tabletop Device Accelerates Electrons to 2 GeV
AUSTIN, Texas, June 21, 2013 — The acceleration of electrons to a speed of 2 gigaelectron volts (GeV) has been accomplished in a tabletop setup. Until now, achieving that level of x-ray energy has required a multimillion-dollar accelerator nearly 200 m long. “We have...
Holograms Enabled by $10 Optical Chip
CAMBRIDGE, Mass., June 20, 2013 — An optical chip built by an MIT graduate student at a cost of $10 could be a “game changer” for holography, enhancing the resolution of conventional 2-D displays and enabling color holographic videos suitable for 3-D television.
Atom-Light Entanglement Created On-Demand
ATLANTA, June 19, 2013 — A state-insensitive optical trap could prove promising for the development of quantum networking, researchers in Georgia have found.
Probes Light Up Synaptic Structures that Store Memories
LOS ANGELES, June 19, 2013 — Microscopic probes that light up synapses in living neurons could give scientists insight into how these structures change when new memories are formed.
Breakthrough Enables Development of Photosensitive Drugs
BARCELONA, Spain, June 18, 2013 — A chemical nanoengineering breakthrough favoring the development of light-regulated therapeutic molecules could lead to personalized medicine that limits treatment time of a given region and reduces unwanted results, a multidisciplinary team has...
Microphone Listens with Light
OSLO, Norway, June 18, 2013 — Listening to a conference call can leave you on the edge of your seat craning to hear what the person on the other end of the call is trying to say. But, a new sensor developed in Norway could change all that, giving microphones hyper-acute hearing...
3-D Maps of Blood Vessels in Brain Reveal Surprises
SAN DIEGO, June 17, 2013 — Blood vessels within a sensory area of a mouse’s brain loop and connect in unexpected ways, a new 3-D map has revealed. The findings could help scientists better explore what the cerebral cortex means for functional imaging of the brain and the...
QD Method Combines Best of Optical, Electron Microscopy
GAITHERSBURG, Md., June 17, 2013 — A fast, versatile and high-resolution technique that combines the best of optical and scanning electron microscopy could provide surface and subsurface viewing of features as small as 10 nm in size.
