CAMBRIDGE, Mass., July 6, 2012 — By coating photovoltaic cells with liquid silicone, scientists from Fraunhofer and Dow Corning Corp. have discovered that the lamination could yield more robust, sustainable solar cells.
Search for Higgs Boson at LHC Reveals New Particle
GENEVA, July 5, 2012 — Two Large Hadron Collider (LHC) experiments presented preliminary results Wednesday that describe a new particle consistent with the long-sought Higgs boson, the famous missing ingredient in the Standard Model of particle physics. The findings could...
Moth Eyes May Enhance Medical Imaging
NEW YORK, July 3, 2012 — New nanoscale materials modeled after the eye of a moth can improve the light-capturing efficiency of x-ray machines and similar medical imaging devices.
Plasma’s Potential for Photolithography Pursued
SEATTLE, July 3, 2012 — Fusion energy work over the past decade to harness the energy-generating mechanism of the sun has now yielded bright high-energy light needed to etch smaller microchips.
Laser Probes Pollution Particles
HAMBURG, Germany, and MENLO PARK, Calif., July 2, 2012 — A new investigation using x-rays from the Linac Coherent Light Source has helped researchers better understand the structure of airborne soot particles. Visualizing the structure of individual aerosol particles in the air for the first time will...
South African Olympic Team Includes a Laser Tech
PRETORIA, South Africa, July 2, 2012 — One South African archer is turning to laser science to improve her accuracy and gain an advantage at the 2012 London Olympics.
Technique Could Broaden Uses of Titanium Dioxide
RALEIGH, N.C., July 2, 2012 — A new method to control the phase of titanium dioxide at room temperature could make it more efficient in applications such as photovoltaic cells, smart sensors, optical communication technologies, hydrogen production and antimicrobial coatings.
Coupled lasers cancel each other out
VIENNA – The discovery that coupling two microlasers shuts them both off instead of emitting more light could prove significant for technologies that combine electronics and photonics. The “laser blackout” effect, discovered by scientists at...
First heralded single photon generated from silicon
SAN DIEGO – For the first time, a heralded single photon has been generated from a silicon chip. The discovery – made by a consortium of researchers from the University of California, San Diego, the National Institute of Standards and Technology...
Four-wave mixing generates superluminal pulses
GAITHERSBURG, Md. – A novel four-wave mixing technique that restructures parts of light pulses to travel faster than the speed of light could improve the timing of communications signals and help examine the propagation of quantum correlations. Einstein’s...
Gamma ray refraction could launch nuclear photonics
GRENOBLE, France – An experiment in which gamma rays were bent like ordinary light overturns decades of theoretical predictions and opens the door to a new field of research called nuclear photonics. Gamma rays are essentially a highly energetic form of light....
Laser creates cheaper free-form optics
AACHEN, Germany – A new process for fabricating small batches of nonspherical glass optical components will allow manufacturers to produce high-quality, customizable optical components of any geometry quickly and inexpensively. High-speed laser ablation of fused...
Release process holds promise for GaN semiconductors
TOKYO – Nitride semiconductors grow only on certain surfaces, and their utility is limited by the substrate on which they are fabricated. But a new release process not only makes the method cheaper and easier, it also expands the potential uses of the...
Single entangled photon creation unlocked
ATLANTA – A new technique can produce single photons with specific properties more efficiently and about 1000 times faster than the current methods, an important advance for several research areas, including quantum information processing and quantum network...
Single nanomaterial yields a laser rainbow
PROVIDENCE, R.I. – Nanocrystals that produce red, green and blue laser light from a single material could lead to digital displays and other devices that employ a variety of laser colors simultaneously. Red, green and blue lasers have become small and cheap...
Solar cell-like implant stimulates optic nerve
STANFORD, Calif. – A new retinal prosthesis that uses technology similar to that found in solar cells could restore sight to those who suffer from degenerative eye diseases such as macular degeneration and retinitis pigmentosa. Researchers at Stanford University...
Students’ QDs win regional Cleantech Challenge
SALT LAKE CITY – Students at the University of Utah recently won $100,000 and first place in the regional CU Cleantech New Venture Challenge for their quantum dot technology. Compared with other materials, quantum dots require less energy for emitting light....
Army’s New Weapon: Laser-Guided Lightning
PICATINNY ARSENAL, N.J., June 29, 2012 — Picatinny scientists and engineers are developing a device that will shoot lightning bolts down laser beams to destroy targets. The Laser-Induced Plasma Channel is designed to take out targets that conduct electricity better than the air or ground...
Photonic Crystals Help Fish See in the Murk
LEIPZIG, Germany, June 29, 2012 — The elephantnose fish, thought to be blind, was found to have light-reflecting cups lined with photonic crystals in its retinas that help it navigate in its dark, murky environment. Researchers think this unusual eye structure might inform future...
Photonics Professor Wins Krupp Prize
KARLSRUHE, Germany, June 29, 2012 — The Karlsruhe Institute of Technology photonics professor received the 2012 Alfried Krupp Prize for Young University Teachers, endowed with €1 million.
Light Focused Deep Inside Tissue
PASADENA, Calif., June 28, 2012 — A new procedure that is as simple as an ultrasound more than doubles the depth that light can be focused inside biological tissues and soon could enable doctors to perform incision-free surgery or to diagnose cancer by seeing tumors inside the body.
Solar Cells Slimmed with Nanosandwich
RALEIGH, N.C., June 28, 2012 — A new technique to fabricate slimmer thin-film solar cells without compromising their ability to absorb solar energy could reduce production costs for the technology.
3-D Optical Cavities Made from Metamaterials
BERKELEY, Calif., June 27, 2012 — Three-dimensional nanoscale optical cavities made from metamaterials have the potential to generate the most intense nanolaser beams to date and hold promise for a range of other technologies, including LEDs, optical sensing, nonlinear optics,...
Computer Chips Made Rewritable with Light
NEW YORK, June 27, 2012 — A new technique for making rewritable computer chips uses laser light to control the spin of an atom’s nucleus to encode information, bringing ultrafast quantum computing a step closer to reality.
