University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made waveguides -- the equivalent of wires -- that carried and bent this form of light, also known as terahertz radiation, which is the last unexploited portion of the electromagnetic spectrum.

Electricity is carried through metal wires. Light used for communication is transmitted through fiberoptic cables and split into different colors or “channels” of information using devices called waveguides. In a study published in Optics Express, Ajay Nahata, study leader and associate professor of electrical and computer engineering at the University of Utah, and colleagues report they designed stainless steel foil sheets with patterns of perforations that successfully served as wire-like waveguides to transmit, bend, split or combine terahertz radiation.

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.

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 optical frequency comb spectroscopy, may one day allow doctors to screen people for certain diseases simply by sampling their breath. “This technique can give a broad picture of many different molecules in the breath all at once,” says Jun Ye, who led the research. He is a fellow of JILA, a fellow of NIST and a professor adjoint at CU-Boulder’s Department of Physics.

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 butterfly through 4 mm of plaster. They believe their technique is capable of seeing even deeper. A paper on the research is published in the February edition of Optics Communications.
