SAN DIEGO, California, February 27 /PRNewswire/ -- Alcatel-Lucent (Euronext Paris and NYSE: ALU) today announced that Bob Tkach, director of Transmission Systems research at Bell Labs, received the 22nd John Tyndall Award, the highest recognition in the optical telecommunications community, during a ceremony at the OFC/NFOEC conference in San Diego, California. Tkach was recognized for his long and prolific body of optical networking research that includes inventing many of the fundamental technologies that are now the basis of high-capacity wave division multiplexing (WDM) systems. These…

Intexys Photonics introduces its family of Optical Engines for parallel optics applications and more particularly for the Optical Active Cable emerging market.
(Logo: http://www.newscom.com/cgi-bin/prnh/20070905/AQW066LOGO )
The Optical Engine Family consists of a (4+4) x5Gbit/s Infiniband compliant engine and a QSFP version just released. The family will also include a (4+4) x10Gbit/s engine in March with a 12x10Gbs engine in late 2008.
The engines are manufactured using the Intexys patented "Full-Flip-Chip" concept…
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person’s breath with laser light they can detect molecules in the breath that may be markers for diseases like asthma or cancer. While many studies have been done to showcase the potential of optical technologies for breath analysis, the JILA approach takes an important step toward demonstrating the full power of optics for this prospective medical application.
The technique, called cavity-enhanced direct…

Mobile World Congress -- OmniVision Technologies, Inc. (Nasdaq: OVTI), the world's largest supplier of CMOS image sensors, today claimed a mobile handset industry first with the introduction of the OV3642, a 1/4-inch, 3 megapixel CameraChip(TM) sensor with TrueFocus(TM) technology embedded on-chip. The fully integrated OV3642 is built with OmniVision's new OmniPixel3-HS(TM) technology which delivers double the sensitivity (960mV/Lux-sec) of other manufacturers' 1/4" 3 megapixel SOC sensors, offering best in class low light performance.

"T-rays", pulses of terahertz radiation, could let art historians see murals hidden beneath coats of plaster or paint in centuries-old buildings in much the same way X-rays let doctors see through skin and could also illuminate penciled sketches under paintings on canvas without harming the artwork, according to new research.
Current methods of imaging underdrawings can't detect certain art materials such as graphite or sanguine, a red chalk that some of the masters are believed to have used.
The team of researchers used terahertz imaging to detect colored paints and a graphite drawing of a…
It isn't time to rewrite the Corpus Hermeticum just yet but a University of Rochester optical scientist has come close - he has used a tabletop laser to turn pure aluminum gold. And blue. And gray. And many other colors. And it works for every other metal tested, including platinum, titanium, tungsten, silver, and gold.
Chunlei Guo, the researcher who a year ago used intense laser light to alter the properties of a variety of metals to render them pitch black, has pushed the same process further in a paper in today’s Applied Physics Letters. He now believes it’s possible to alter the…

Dark-field images provide more detail than ordinary x-ray radiographs and could be used to identify explosives in hand luggage, diagnose the onset of breast cancer or Alzheimer’s disease and pinpoint hairline cracks or corrosion in functional structures.
The issue has been that the wavelengths needed for dark-field images required sophisticated optics that could only be produced at facilities like the Paul Scherrer Institute (PSI)’s 300m-diameter, $200 million synchrotron. Now researchers at PSI and Ecole Polytechnique Fédérale de Lausanne in Switzerland have developed a novel method…

Broadband access has transformed the economic potential of the internet but the ADSL technology that delivers broadband to homes over traditional copper telephone wires is reaching its limit of around 10 megabits per second. If we want speeds ten times faster we need to replace the copper with optical fibers.
Optical fibers carry signals with light rather than electricity. They have been used in telecommunications for many years, especially over ‘long-haul’ links such as transatlantic cables and other trunk routes. Professor Henri Benisty, of the Institute of Optics Graduate School near Paris…
