Light Elongates Day
Jul 1, 2007 — It’s tough fitting one’s busy schedule into the confines of a 24-hour day. If only it could be extended to 25 hours. Researchers may have found a way to do just that, at least as far as the brain’s circadian rhythms are concerned. The internal clock that controls our circadian (from the Latin “circa diem,” meaning “for about a day”) rhythms is, for most people, synchronized pretty closely to the rotation of the Earth — a 24-hour day — by the light-dark cycle. But this biological regulator...
Growth and Challenges in OLED Manufacturing
Jul 1, 2007 — Organic light-emitting diodes (OLEDs) are quickly becoming the next generation of small displays. Although the technology is still emerging, it has been used already in personal media displays such as MP3 players and mobile phone subdisplays. The...
Managing Light to Increase Efficiency in LCDs
Jul 1, 2007 — Consumers plan to purchase 72 million LCD TVs in 2007 and 98 million in 2008, when sales will surpass cathode-ray tube TV unit sales for the first time, according to the research firm DisplaySearch of Austin, Texas. The industry is racing to build...
Manufacturing Large LCDs while Maintaining Yields
Jul 1, 2007 — As thin-film transistor LCD panel makers produce increasingly larger televisions, fewer displays fit onto the glass substrate during the production process. Whereas fifteen 32-in.-wide displays fit onto an eighth-generation substrate, only six...
Keeping Pace with the Global Display Industry
Jul 1, 2007 — Global displays are poised to overtake semiconductors and become a $100 billion industry. Flat panel displays, and in particular liquid crystal displays (LCDs), are ubiquitous and are found in products ranging from cell phones to big-screen TVs. It...
Lasing in a Gain-Guided, Index-Antiguided Fiber
Jul 1, 2007 — In the past decade and a half, fiber lasers with very high multimode output powers have been developed by doping the core of such fibers with ions that can lase. These fiber lasers are pumped by light from diode-laser arrays that is coupled into...
Nanoscale Light Detectors Provide Mega-Performance
Jul 1, 2007 — On the surface, nanowires would seem to make poor light detectors, but it is a nanowire’s surface that produces just the opposite outcome. Those are the findings of a team of scientists from the University of California, San Diego, that investigated...
Speedy Spectroscopy of Single Nanoparticles
Jul 1, 2007 — Nanoparticles present distinct research problems. Because of variations among production batches, investigators tend to choose to study individual particles. Doing so, however, is technically challenging, and it is difficult to generate meaningful...
Better OLEDs, Perhaps, Thanks to a Holey Electrode
Jul 1, 2007 — The makers of organic LEDs face a challenge. The devices are constructed from a series of organic semiconductor layers sandwiched between a cathode and anode, which must be conductive and transparent. Unfortunately, the best and least expensive...
Two Colors, One Dopant
Jul 1, 2007 — A group of researchers from the Institute of Ion Beam Physics and Materials Research at Forschungszentrum Dresden-Rossendorf in Germany has discovered that the rare-earth element europium can do something rare. When used in a silicon wafer as a...
AFM Characterizes Bubbles that Should Not Be
Jul 1, 2007 — Nanobubbles should not exist because they defy a law of physics. Bubbles with nanometer-size radii should have high pressure within them that causes them to be squeezed out in less than a second, according to LaPlace’s Law. However, nanobubbles last...
A Smart, Small Scanner
Jul 1, 2007 — A team of researchers from Japan has shown that even the smallest optical scanner can pack plenty of smarts, thanks to innovations in fabrication. A group comprising members from the Tokyo-based National Institute of Advanced Industrial Science and...
FO CONNECTORS
Jul 1, 2007 — The Light Brigade has released “Fiber Optic Connectors,” an addition to its “Staff Development” series of instructional DVDs. The menu-based videodisc addresses the discrete parts of connectors, including plugs, receptacles/adapters,...
DESIGN SOFTWARE
Jul 1, 2007 — A supplier of photonic design and simulation software, RSoft Design Group Inc. publishes the RSoft Design Group Review newsletter twice a year. The July issue is scheduled to highlight RSoft CAD 8.0, which adds 3-D editing capability and a...
OPTICS CD-ROM
Jul 1, 2007 — Optics Technology Inc. has released a compact disc that details its optical design and fabrication capabilities. Providing a video overview of the company’s optical services, the disc covers equipment for optical grinding and polishing; precision...
