Silicon Raman Laser Has Low Threshold, High Power
Jul 1, 2007 — In the past three years, several research groups have demonstrated Raman lasers in silicon. That is important because silicon is the basic building block of semiconductor electronics, and the integration of electronics and photonics would be greatly enhanced by the existence of a silicon laser. Silicon’s indirect bandgap prevents it from lasing as other semiconductors do — when holes and electrons combine — and researchers have finessed this problem by creating a laser based on a completely...
Applied Materials Names Head of New Silicon Systems Group
Jun 21, 2007 — Applied Materials Inc. of Santa Clara, Calif., announced yesterday that Tom St. Dennis, senior vice president, has been named general manager of its new Silicon Systems Group, effective immediately. The Silicon Systems Group consolidates the...
'Spinplasmonics' Field Created
EDMONTON, Alberta, May 31, 2007 -- By combining two nanotechnology fields -- spintronics and plasmonics -- researchers have found a novel way to control the quantum state of an electron's spin and created a new technology, "spinplasmonics." A University of Alberta research team...
'Spin Transport' Controlled in Silicon
NEWARK, Del., May 21, 2007 -- The magnet-like spin properties of electrons have been measured and controlled in silicon for the first time, research that could lead to dramatically improved computers and cell phones. The discovery advances the nascent field of spintronics,...
Nanotubes Cool Microchips
TROY, N.Y., April 3, 2007 -- Carbon nanotubes have proven to dissipate microchip heat as effectively as copper and could be integrated into ever-smaller cell phones, digital audio players and personal digital assistants to help ensure the devices don't overheat. The chips...
Microprocessing Technique Yields Ultrathin Membranes
STUTTGART, Germany, and MANCHESTER, England, March 5, 2007 -- Using a fabrication method for producing microprocessors, scientists have created what they said is the thinnest material that will ever exist: Carbon membranes that are only one atom thick. The membrane may allow them to examine individual...
Ultrafast Data Transmit Rates a Hot Topic at OFC/NFOEC
ANAHEIM, Calif., Feb. 27, 2007 -- Many new breakthroughs and innovations in fiber optics and associated technologies -- such as record-breaking data transmission rates, new fiber light sources for food inspection and faster space laser communications -- will be presented next month...

Ultrathin Silicon Filter Sorts Single Molecules
ROCHESTER, N.Y., Feb. 15, 2007 -- A recently developed porous silicon membrane that is thousands of times thinner than similar filters used today sorts objects as small as proteins and has potential applications ranging from fuel cells to stem cells to microchip...
'Optics on a Chip' Melds Photonic Circuitry, Silicon
CAMBRIDGE, Mass., Feb. 7, 2007 -- Using microphotonics, researchers have split the light from an optic fiber in an integrated, on-chip way, controlled the random polarization of the two beams and then reconnected them. The breakthrough in "optics on a chip" technology could lead to...
Roughing Up Silicon Improves Near-Infrared Performance
Feb 1, 2007 — Despite its electronic and visible spectrum prowess, silicon is an infrared weakling. Beyond 1100 nm, the material absorbs little radiation and, therefore, the response of silicon-based photodiodes fades to almost nothing. Now a research team...
Freescale, IBM to Collaborate on Future Semiconductor Technologies
Jan 23, 2007 — Austin, Texas-based Freescale Semiconductor and IBM of Armonk, N.Y., today announced that Freescale will join the IBM technology alliance for joint semiconductor research and development. The agreement includes CMOS and silicon-on-insulator (SOI)...
Plextronics Gets $750K to Develop Technology for Organic Solar Cells
Jan 23, 2007 — Plextronics, a Pittsburgh-based developer of active-layer technology for printed electronic devices, announced it has received $750,000 in funding from the Sustainable Energy Fund of Central Eastern Pennsylvania to further develop Plexcore PV...
Wrinkled 'Skin' Created on Polymers
CAMBRIDGE, Mass., Jan. 18, 2007 -- By controlling the direction and intensity of a focused ion beam, researchers have sculpted patterns on flat areas of a silicon-based organic polymer in much the same way that an airbrush moves over fabric. This new method for developing wrinkled...
$100M Raised to Manufacture Plastic Semiconductors
CAMBRIDGE, England, Jan. 11, 2006 -- Plastic Logic announced last week that it has raised $100 million to fund construction of the first factory to manufacture semiconductors out of plastic instead of silicon. The facility will produce flexible active-matrix display modules for use in...
Light Buffered on a Chip
YORKTOWN HEIGHTS, N.Y., December 27, 2006 -- IBM announced its researchers have built a device capable of delaying, or "buffering," the flow of light on a silicon chip, an achievement needed to pave the way for ultrafast computers that use light instead of electric signals to process data....
OIDA: Energy, Industrial Laser Markets Most Promising
WASHINGTON, Dec. 14, 2006 -- 2006 has been a good year for the optoelectronics industry, with most markets showing double-digit growth, said Michael Lebby, president and CEO of the Optoelectronics Industry Development Association (OIDA) at the organization's annual forum last...
New Technique Brings Flexible Electronics Closer to Reality
LOS ANGELES and STANFORD, Calif., Dec. 13, 2006 -- Researchers have devised a method for printing patterns of high-performance organic single-crystal transistors on surfaces such as silicon wafers and flexible plastic, which could enable fast, bendable electronics such as low-cost sensors on product...
Transport Measured Through a Single Atom in a Transistor
DELFT, Netherlands, Nov. 27, 2006 -- Transport has been successfully measured through a single atom in a transistor, giving researchers new insights into the behavior of so-called dopant atoms in silicon, one of the stumbling blocks impeding the further miniaturization of electronics....
