Ti:Sapphire Laser Drives Accelerator on Chip
STANFORD, Calif., Oct. 1, 2013 — An advance that uses commercial lasers and low-cost, mass-production techniques could set the stage for a new generation of "tabletop" particle accelerators that are less expensive for use in science and medicine. Current state-of-the-art accelerators use microwaves to boost the energy of electrons. Researchers have sought more economical alternatives, and this new technique, which uses ultrafast lasers to drive the accelerator, is a leading candidate. A team that included scientists f...
Well-rounded Molecules Make Better Light Emitters
SALT LAKE CITY, Sept. 30, 2013 — The more well-rounded the organic molecule the better when it comes to maximizing light emission, an international team of physicists and chemists have found. A team led by the University of Utah working to develop more efficient OLEDs believes it...
Handheld Lidar Creates Leaning Tower of Pisa in 3-D
HIGHETT, Australia, Sept. 27, 2013 — Using a handheld laser mapping system, Australian researchers have created the first-ever 3-D map of the inside of Italy’s Leaning Tower of Pisa, a site whose cramped stairs and complex architecture have prevented previous mapping technologies...
University of Calgary Launches Institute for Quantum Science and Technology
CALGARY, Alberta, Canada, Sept. 27, 2013 — The University of Calgary has announced the creation of the Institute for Quantum Science and Technology (IQST), a unit dedicated to research, training and outreach in the field of quantum science. The institute will focus on themes of quantum...
THz Sensor to Detect Viruses Before Outbreaks
DAYTON, Ohio, Sept. 26, 2013 — A new project aims to develop a sensor that uses gigahertz-to-terahertz (GHz-to-THz) radiation to detect viruses captured in nanofluidic chips, with the goal of using the system quickly in places where large, highly mobile groups congregate, such as...
Electrical Quantum States Translated to Optical Ones
SANTA BARBARA, Calif., Sept. 24, 2013 — Using a piezoelectric optomechanical crystal to generate a strong optical response, a UC Santa Barbara team has demonstrated a nanomechanical interface between optics and electronics, the first — and arguably the most challenging — step...
Transparent OLED Display Folds, Stretches
LOS ANGELES, Sept. 24, 2013 — A transparent OLED can be repeatedly stretched, folded and twisted at room temperature while remaining lit and retaining its original shape. The ultrastretchable display, created at UCLA’s Henry Samueli School of Engineering and Applied...
A BOLD Idea for Handling ‘Big Data’
HOUSTON, Sept. 23, 2013 — A new optical network being developed at Rice University will help streamline demanding, data-intensive computations in a customized, energy-efficient way. The new network, BOLD — short for Big Data and Optical Lightpaths-Driven Networked...
Bioengineers Aim for ‘Visual Cortex on Silicon’
UNIVERSITY PARK, Pa. & SAN DIEGO, Sept. 20, 2013 — A multi-institutional group aims to create a machine vision system that approaches the cognitive abilities of the human brain. Such a system would enable computers to not only record images, but also to understand visual content at up to a thousand...
South Africans Develop ‘Digital Laser’
PRETORIA, South Africa, Sept. 20, 2013 — South Africa’s Council for Scientific and Industrial Research (CSIR) held a press conference this week to announce it has developed the first digital laser, a milestone its creators say represents a paradigm shift for laser resonators. In...
Human/Insect Lens Adds Depth to Wide-Angle Views
COLUMBUS, Ohio, Sept. 19, 2013 — A new lens that combines the focusing ability of the human eye with an insect’s wide-angle view could help make a confocal microscope with no moving parts, or improve surgical imaging. "Our eye can change focus. An insect eye is made of many...
LLNL Awarded $45M to Build Laser in Czech Republic
LIVERMORE, Calif., Sept. 19, 2013 — Lawrence Livermore National Laboratory (LLNL) has been awarded more than $45 million to develop and deliver a state-of-the-art laser system for the European Union’s Extreme Light Infrastructure Beamlines facility (ELI Beamlines), now under...
Graphene on Chip Closing the Gap with Germanium
VIENNA, CAMBRIDGE, Mass., & HONG KONG, Sept. 17, 2013 — Graphene-based photodetectors can efficiently convert infrared light into electrical signals, three independent studies report this week. The work "makes it very likely that graphene will soon replace germanium and compound semiconductors in...
Haptic Optical Tweezers Let Us ‘Feel’ Microstructures
PARIS, Sept. 16, 2013 — A new technology called haptic optical tweezers allows microscope users to manipulate samples by sight and touch, which could improve dexterity of micromanipulation and microassembly. The tweezers “will become an invaluable tool for force...
Rochester Cluster Presents Business, Education, Achievement Awards
ROCHESTER, N.Y., Sept. 16, 2013 — The Rochester Regional Photonics Cluster presented awards for entrepreneurship, leadership and education as well as a special lifetime achievement award at its annual meeting Sept. 5 at the Rochester Museum & Science Center.
Tunable Polymer Could Make Truly White OLED
SALT LAKE CITY, Sept. 13, 2013 — Doping an organic polymer with platinum atoms makes the light it emits tunable, which could lead to the realization of cheaper, more efficient and truly white OLEDs. Existing white OLED displays use different organic polymers that emit different...
Laser Spectroscopy Overcomes Measurement Challenge
PHILADELPHIA, Sept. 12, 2013 — A "remarkably simple" laser-based approach overcomes the challenge of measuring key aspects of electron behavior while designing ever-smaller components -- which could allow cellphones, laptops and tablets to get increasingly thinner and more energy...
Taking the ‘Fry’ Out of the Skyscraper
LONDON, Sept. 12, 2013 — A pan-European consortium aims to give city planners key environmental analytic tools, something that could prevent the building of another Jaguar-melting, egg-frying, cornea-searing "fryscraper." The curved surface of the $378 million, 37-story...
Bioimaging Laser Branches Out to Bomb Detection
EAST LANSING, Mich., Sept. 10, 2013 — A method originally developed for biomedical imaging puts the possibility of bomb-detecting lasers at security checkpoints within reach. Michigan State University chemistry professor Marcos Dantus has developed a laser that senses micro traces of...
New UV LED Suits Commercial Applications
COLUMBUS, Ohio, Sept. 10, 2013 — An ultraviolet LED created from semiconductor nanowires doped with the rare-earth element gadolinium could lead to more portable and low-cost commercial uses of the technology.
