Plasmonics May Hold Key to All-Optical Chips
Jun 9, 2011 — A rapidly growing branch of physics promises all-optical computer chips and ultrafast computing speeds. Plasmonics, also called “light on a wire,” exploits the nanoscale interaction of light and metal and is a focus of research in the...
Fujitsu Cuts Optical Switch Power Consumption in Half
KAWASAKI, Japan, Nov. 10, 2010 — Fujitsu Laboratories Ltd. announced its new optical waveguide switch consumes only half the power of a traditional switch through the use of fine-patterned silicon germanium instead of traditional silicon in the refractive-index modulator. Just as...
Physicists Win MacArthur Grants
ITHACA, N.Y., & CAMBRIDGE, Mass., Sept. 28, 2010 — An optical physicist at Cornell University working to develop silicon-based devices that harness the information-processing capabilities of light and an MIT physicist whose research links the worlds of quantum mechanics and astronomy were named...
Designer molecules promise all-optical processing
ATLANTA – Supporters of all-optical switching say it will allow dramatic speed increases in data communications by eliminating the need to convert photonic signals to electronic signals – and back. All-optical processing – switching light using...
Catching photons in a bottle
MAINZ, Germany – Physicists at Johannes Gutenberg University have developed a bottle-shaped, monolithic microresonator that captures light and tunes it to arbitrary optical frequencies. To do this, they stretched a glass fiber until it reached about half the...
Northumbria Opens Research Labs
NEWCASTLE UPON TYNE, England, May 9, 2007 -- A new £600,000 ($1.2 million) facility for Northumbria and Newcastle universities to teach and conduct research into photonic and radio-frequency (RF) communications, microwave communications and microwave holography was officially opened this week...
Fastest Molecules Ever Boost Optical Technologies
PULLMAN, Wash., Jan. 3, 2007 -- The Internet could soon shift into overdrive thanks to a new generation of optical molecules developed and tested by an international team of researchers. The new materials, organic molecules known as chromophores, interact 50 percent more...
All-Optical Frequency Shifter Demonstrated
Apr 1, 2003 — As the demand for speed and bandwidth in communications networks increases, new approaches to switching and routing are under study. Now researchers at the University of Illinois at Urbana-Champaign have developed an all-optical device that rapidly...
