Research & Technology News
Revolutionizing Spintronics
MENLO PARK, Calif., June 16, 2009 – Physicists at the Department of Energy's (DoE) SLAC National Accelerator Laboratory and Stanford University have now confirmed that there is an exotic type of material that could one day provide dramatically faster, more efficient computer chips.
4 Photons Controlled on Chip
BRISTOL, UK, June 9, 2009 – A team of physicists and engineers at the University of Bristol Centre for Quantum Photonics has demonstrated the ultraprecise manipulation skills needed to make a major advance toward quantum technologies by precisely controlling four photons on a...
Light's Might Harnessed
PASADENA, Calif., June 5, 2009 – A nanoscale device created at the California Institute of Technology exploits the mechanical properties of light to create an optomechanical cavity in which interactions between light and motion are greatly strengthened and enhanced. It harnesses...
A handy way to detect life
BALTIMORE – The next time the soil of an alien world is examined for life, scientists may already have a good idea where to dig. Thanks to a new technique, they might be able to remotely detect life from the comfort of Earth, pinpointing promising locations for...
From battlefield to lighting fixture
Jun 1, 2009 — Rather than diverting laser-guided weapons, a technology developed under a US Air Force contract is now blending and controlling multiple LEDs in civilian applications. The military effort originally focused on developing a countermeasure system...
Get ready for laser-powered 3-D TV
IRVINE, Calif. – Last October, Mitsubishi Digital Electronics America Inc. announced that it was bringing to market laser-powered television. Called LaserVue, it lights up the screen with high-color-purity red, green and blue laser light instead of white lightbulbs...
Guiding reindeer through a warming world
FINNMARK, Norway – While most Americans think of reindeer only in conjunction with holiday joy, the real animals and their herders live in the Arctic year-round and are experiencing global warming’s serious effects on snow cover and migration patterns. To help...
On the trail of arsenic
AMHERST, Mass. – In stories of murder by poisoning, both fictitious and real, arsenic has long been a key player. Just the mention of the word brings to mind dark deeds, secret plans and – the family deck? Indeed. CCA-treated wood, a type of pressure-treated...
Patent Reform Act of 2009: benefit v. detriment
Jun 1, 2009 — If put into effect, the Patent Reform Act of 2009 will change US patent law considerably for the first time since 1952. Already the bill has ignited a conflict between those who say it will improve the quality of patents while limiting needless...
Throwing curved light bullets
TUCSON, Ariz. – Researchers have devised a way to curve laser beams in the air by converting a standard directional beam into a self-bending Airy beam. The development may help with atmospheric applications, particularly with the ability to redirect lightning to...
When things don’t go swimmingly
CAMBRIDGE, Mass. — Tiny single-celled creatures known as phytoplankton form the base of the ocean’s marine food web and, together, produce half the world’s oxygen. Generally speaking, if all goes well, these creatures, of which there are many species, swim to the...
Optical Device Records in 5-D
MELBOURNE, Australia, May 22, 2009 – Optical recording technologies such as DVDs could have a storage capacity of 1.6 terabytes, or the equivalent of 2000 discs, announced researchers at Swinburne University of Technology in Melbourne, Australia. The new optical device records in 5-D...
Cloak has Tapered Waveguide
WEST LAFAYETTE, Ind., May 20, 2009 -- Using a specially tapered optical waveguide instead of exotic metamaterials that require complex nanofabrication, researchers have created a simplified invisibility cloak that, unlike previous ones, works for all colors of the visible spectrum. The...
Pencil-thin LCD Panel Debuts
SEOUL, Korea, May 20, 2009 -- LG Display Co. Ltd. announced Tuesday that by using an LED backlight assembly and other slimming technologies, it developed large LCD TV panels that are only as thick as a pencil and weigh less than 16 lbs.
Liquid Lenses Focus Light
UNIVERSITY PARK, Pa., May 18, 2009 – Tunable fluidic microlenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to Pennsylvania State University engineers. They may also provide imaging in medical devices, eliminating...
New Probe to Measure Freeform Optics
ROCHESTER, N.Y., May 15, 2009 -- Demand for freeform optical elements is on the rise, and they have gotten easier to make, but at the moment no commercial systems exist to measure such components. Researchers at ASE Optics Inc. in Rochester, N.Y., have demonstrated that a scanning...
Blink-Free Nanocrystals Made
May 11, 2009 — A new semiconducting nanocrystal that continuously emits light without "blinking" has been developed by scientists and engineers. Potential applications for the device include lasers, brighter LEDs, solar cells, and biological imaging. For more than...
Tiny Lasers Plug ‘Green Gap’
TAMPERE, Finland, May 5, 2009 – Compact lasers can work in the 'green gap' -- formerly inaccessible parts of the spectrum -- and are suitable for mass production, thanks to pioneering work by a European consortium.
Building better optical components using plasmonics
BELFAST, UK – A team of European researchers has demonstrated what could be the basis of novel photonic components. Through the exploitation of plasma oscillations, these and other plasmonic devices potentially could manipulate both electronic and photonic...
Camera chips survive bus blast and tell a tale
ABERDEEN, Md. – After the bus blew up, the search was on for survivors. However, the goal was not to rescue people. Instead, the objective was memory chips. Before the blast, the chips had been in cameras mounted inside the bus. Afterward, they were part of the...
Energy-efficient microchip provides fresh slate for students in India
HOUSTON – According to the District Information System for Education, which tracks statistics on education in rural India, nearly 106 million schoolchildren do not have access to electricity, and more than 417,000 attend primary schools with fewer than three...
No more buffing: self-healing coatings
HATTIESBURG, Miss. – We’ve all had it happen at least once. You make your way out to the parking lot, figure out where you left your car, reach for the door handle – and freeze. That scratch wasn’t there when you left your vehicle earlier, and it doesn’t look as if...
Passive optical networks, higher power lasers keys to broadband service in rural areas
MELBOURNE, Australia – The benefits of high-speed Internet – videoconferencing, high-definition television, interactive online gaming – often are not available to rural dwellers, those who live well beyond the limits of urban and suburban areas. Technologies such as...
Photonics applications highlight Munich
MUNICH, Germany – Photonics applications will be the headliners when Laser World of Photonics 2009 convenes next month. The show, to be held at the New Munich Trade Fair Centre from June 15 to 18, will give investors, companies and researchers an opportunity to...
Smart homes take care of their elderly residents
DUISBURG, Germany – In the future, instead of leaving the comfort of home, the elderly may be able to live on their own with the assistance of sensors within the residence that monitor them continuously and autonomously. As the aging population continues to increase...
