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...
Holograms Hold 500 GB on Disc
NISKAYUNA, N.Y., April 29, 2009 – Microholographic technology was used to produce a standard-size DVD with a 500-GB storage capacity, the equivalent of 100 DVDs, GE Global Research announced.
Scrambled Light Hones Images
PRINCETON, N.J., April 22, 2009 – A new imaging system can unscramble the rich visual information provided by nonlinear optical materials to produce sharper images with a wider field of view. This method makes it possible to create high-resolution images at any chosen point – at the...
Laser Polarization Controlled
CAMBRIDGE, Mass., April 13, 2009 -- Lasers with controlled polarization were demonstrated for the first time through the integration of the polarizer on the laser facet, an innovation that could open new applications in photonics and communications. Harvard Univerity and Hamamatsu...
Curving ‘Light Bullets’
TUCSON, Ariz., April 9, 2009 – Wave patterns called Airy beams, combined with "light bullets" -- short, intense laser pulses so fast the beam is broader than it is wide -- created curving "needle" bullets that might help monitor air pollution, said physicists at the University of...
All the world’s a screen
CAMBRIDGE, Mass. – Put away those phones, and forget the laptop. You won’t need them in the future if an MIT project succeeds. Using a camera, a projector and a mobile computing device, researchers there have turned the whole world into a screen – and fingers waving...
Blurry Future for Russian Laser Optics Market
Apr 1, 2009 — The vast landscape of the Russian Federation is home to more than 800 laser-related organizations and companies spread over 85 cities in 57 regions. Along with other functions they perform, these laser entities train specialists, service laser...
Food safety just got smarter
KINGSTON, R.I. – The hot-button issue of food contamination, it seems, is never far from the headlines, but until now, avoiding it has depended to a great extent upon the decidedly low-tech expiration date. However, thanks to technology developed by Brett Lucht and...
Glass Structuring Agreement
Apr 1, 2009 — MSG Lithoglas AG of Berlin has signed an agreement with Schott AG of Mainz, Germany, for exclusive use of the latter’s process and application intellectual property on the additive structuring of glass. This technology enables the deposition of thin...
Imaging elusive winter sprites
RAMAT AVIV, Israel – “Sprites,” or upper-atmospheric lightning that occurs high above thunderstorm clouds, are a natural phenomenon that have caught the attention of Colin Price, professor and head of the geophysics and planetary sciences department at Tel Aviv...
Practice mirror goes 3-D
Leeds, UK – For a musician, the traditional optical device is the mirror. A violinist stands in front of one while practicing to visualize whether his bow is parallel to the bridge and his instrument positioned optimally in relation to his body. Dr. Kia Ng,...
Quantum communication, without – and with – delay
GAITHERSBURG, Md. – When it comes to computing, some of the lessons we learned in kindergarten really do apply. Algorithms have to take turns. Otherwise, final calculations could be wrong. Such data flow control is done routinely in standard computers. Now the...
Tinier quantum dots
EDMONTON, Alberta, Canada – Quantum dots are fascinating – thousands of atoms, acting together as one, bring us closer and closer to true quantum computing. As amazing as they are, though, they still have their problems, including the need for ultralow operating...
Silicon Emits Visible Light
SYDNEY, Australia, March 27, 2009 – Physicists at the University of Sydney discovered that silicon photonic crystals, which slow laser light, can convert IR wavelengths to green light.
