Lighting the Path to Exascale Computing
YORKTOWN HEIGHTS, N.Y., Dec. 1, 2010 — New chip technology unveiled today by IBM integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using light pulses instead of electrical signals. The advance could bring exascale computers — machines 1000 times faster than today’s best systems — closer to reality.
Plasmonic antenna enhances spectroscopic studies
HOUSTON – The need for technologies that can detect molecules with high sensitivity is important in many fields. For applications ranging from industrial safety to homeland security, single-molecule sensitivity would be a highly valuable tool. Now an optical...
Quantum networks receive memory boost
ATLANTA – Long-distance quantum communication could be a step closer, thanks to a suite of optical technologies developed by researchers at Georgia Institute of Technology. The group has demonstrated a low-noise system for converting photons carrying quantum...
Short, Powerful On-chip Light Pulses Generated
SAN DIEGO, Dec. 1, 2010 — Electrical engineers generated short, powerful light pulses on a chip — an important step toward the optical interconnects that will likely replace the copper wires that carry information between chips within today's computers. University of...
To keep atoms spinning together, don’t let them relax
BERKELEY, Calif. – There’s a new world record, according to researchers who were able to preserve the spin-polarization of atoms in an alkali vapor for about 60 seconds at room temperature, roughly 100 times the previous best. During that time, atoms within the...
Tracking ultrafast laser ablation to tune nanoparticle films
NAPLES, Italy – Ultrafast laser ablation yields two distinctly different plumes, and the behavior of both can be described well by models, researchers report. That information could be used to produce novel nanoparticle films of magnetic and semiconductor...
Lasers Used to ’Hear’ Ripples in Space
PASADENA, Calif., Nov. 30, 2010 — A new system of lasers is being tested that would “hear” gravitational waves, or ripples in space and time, while flying aboard the proposed space mission called Laser Interferometer Space Antenna (LISA). The research team, consisting of...
Flir Camera Detects Gas Leaks
CROISSY-BEAUBOURG, France, Nov. 29, 2010 — BP Chemicals is using Flir Advanced Thermal Solutions’ GasFindIR cameras to visualize and document gas leaks, said Flir. In the production of acetic acid, a highly versatile substance, BP Chemicals is responsible for a significant...
Microscope Aids Study of Single Molecules
AMES, Iowa, Nov. 29, 2010 — By combining atomic force microscopy (AFM) and Förster resonance energy transfer (FRET) technologies, a researcher at Iowa State University has developed new approach toward single-molecule microscopy. Sanjeevi Sivasankar was looking for a...
SETI’s UV LEDs Complete Space Qualification
COLUMBIA, SC, Nov. 29, 2010 — Sensor Electronic Technology Inc. (SETI), together with Stanford University and National Security Technologies of Livermore, Calif., has demonstrated extreme environmental robustness and radiation hardness of its UVTOP deep ultraviolet LEDs. ...
HELIOS Shows Off Laser Silicon Progress
GRENOBLE, France, Nov. 24, 2010 — CEA-Leti, coordinator of the European HELIOS project to accelerate commercialization of silicon photonics, has announced that the consortium has demonstrated a laser and a 10-Gb/s silicon modulator using a technique compatible with complementary...
Simultaneous Cooling, Concentrating of Light Creates Superphoton
BONN, Germany, Nov. 24, 2010 — By devising a way to cool and control light at the same time, a "gas" of photons was made to form the ultracold, high-density quantum state known as a Bose-Einstein condensate. Such photon-filled condensates, thought to be impossible to create until...
Kotura Develops Ultrafast Si Photonics Switch
MONTEREY PARK, Calif., Nov. 23, 2010 — Kotura Inc., a manufacturer of Silicon Photonics products, announced that it has demonstrated an ultrafast, submilliwatt, broadband 2 x 2 optical switch. With switching speeds of 6 ns and power consumption of only 0.6 mW, the 60 nm bandwidth means...
Future Bright for Nanopillar Light Collectors
BERKELEY, Calif., Nov. 22, 2010 — Sunlight represents the cleanest, greenest and far and away the most abundant of all energy sources, and yet its potential remains woefully underutilized. High costs have been a major deterrent to the large-scale applications of silicon-based solar...
Laser Imaging System Screens Nanotubes
WEST LAFAYETTE, Ind., Nov. 22, 2010 — Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a faster and more energy-efficient class of computers and electronics. The semiconducting...
MRI Possibly Useful for Testing Jets
WASHINGTON, D.C., Nov. 22, 2010 — Magnetic resonance imaging (MRI), a medical imaging technology used to image organs and soft tissues, also may hold the key to improving the efficiency of jet engines, according to Lt. Col. Michael Benson, a PhD student in mechanical engineering at...
Direct Green Laser Pico Projector Prototypes Achieved
REDMOND, Wash., Nov 18, 2010 — Microvision Inc., a supplier of ultraminiature projection display technology, has successfully integrated "direct green" laser samples from two leading manufacturers into pico projector benchtop prototypes. This achievement represents an important...
Mitsubishi Red Laser Diode Offers 1W Output
TOKYO, Nov. 18, 2010 — Mitsubishi Electric Corp. has introduced the ML501P73, a 638-nm red laser diode with an output power of 1 W for use in pico projectors and other portable display systems that require a high-brightness red light source. Sample shipments will begin...
Telescope Scientists Share Goddard Award
GREENBELT, Md., Nov. 18, 2010 — Three employees of NASA’s Goddard Space Flight Center have received the 2010 Robert H Goddard Award for Science. The award was bestowed upon Matt Greenhouse, Randy Kimble and Alexander Moiseev for outstanding work in sciences at the center....
‘Space-time’ Cloak Could Hide History
LONDON, Nov. 17, 2010 — Theoretical physicists have taken the idea of creating an invisibility cloak and broadened it to include the object’s movement. Such a "space-time cloak" could be used to hide events, they suggest. Previously a team led by professor Sir John...
Solid-state Sensor Combines Optics, Electronics
PITTSBURGH, Nov. 17, 2010 — University of Pittsburgh researchers have created a nanoscale light sensor that can be combined with near-atomic-size electronic circuitry to produce hybrid optic and electronic devices with new functionality. The team, which also involved...
