Intricate experiment reveals cause of LED droop
SANTA BARBARA, Calif. – The future looks bright for alternative lighting, now that scientists have solved the mystery that causes LEDs to “droop” in efficiency at high currents. The phenomenon known as LED droop has intrigued researchers for years. In 2011, University of California, Santa Barbara, professor Chris Van de Walle and colleagues theorized that a complex nonradiative process known as Auger recombination was behind nitride semiconductor LED droop, whereby injected electrons lose energy to heat...
Kepler could be kaput
Jul 1, 2013 — The Kepler space telescope has discovered 132 planets since its launch in 2009, but now it appears to be on life support, NASA said in late May. Kepler had successfully completed its primary mission and in November had entered an extended phase. The...
Microscopy Technique Could Help Make 3-D Components
GAITHERSBURG, Md., July 1, 2013 — A technique developed several years ago for improving optical microscopes has now been applied to monitoring the next generation of computer chip circuit components, providing a crucial tool for developing 3-D components.
OCT improves S-GRIN lens manufacturing process
ROCHESTER, N.Y. – Spherical gradient in refractive index (S-GRIN) lenses are lightweight and easily deformable, but manufacturing them with high quality and consistency is challenging. Now, researchers at the University of Rochester are embedding OCT into the...
Optical fiber design uses Anderson localization
MILWAUKEE – The first practical application of “Anderson localization” – a Nobel Prize-winning phenomenon proposed in 1958 – has yielded a new method for transmitting light through optical fibers. Data transmission through conventional...
Photonic topological insulator could enable quantum computing
KESALSABA, Israel – As computers get faster and chips get denser, there is a need for smaller light-manipulating devices. But as devices get smaller, imperfections in the fabrication processes can make light move irregularly and unpredictably. To tackle this challenge,...
Plasmon waves control light
CAMBRIDGE, Mass. – A nanoscale coupler that converts optical signals into surface plasmon polaritons can distinguish between different movements of polarized light and can precisely manipulate the signals in one direction or another without damaging them. The device...
Pushing camera design beyond nature’s limits
URBANA, Ill. – A camera design inspired by the ocular systems found in insects, arachnids and crustaceans is being pushed beyond anything that exists in nature. In the May 2 issue of Nature (doi: 10.1038/nature12083), an interdisciplinary team led by John A....
Space telescope spots three super Earths
WASHINGTON – Three super-Earth-sized planets in two newly discovered planetary systems are in a “habitable zone” – a distance from their stars suitable for supporting liquid water – and could potentially support life as we know it,...
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....
First Bonenfant Memorial Scholarship Awarded
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.
