Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. "Everyone uses surface plasmon resonance sensors. They are a multi billion-dollar industry worldwide," said Akhlesh Lakhtakia, the Charles Godfrey Binder (Endowed) professor of engineering science and mechanics, Penn State. "This type of sensor provides a...

U.S. scientists say they have created the tiniest laser since lasers were invented 50 years ago. Researchers at Purdue, Norfolk State and Cornell universities said their achievement might lead to many innovations, including superfast computers that use light instead of electrons to process information, advanced sensors and imaging. The new device -- called a spaser -- is the first of its kind to emit visible light and represents a critical component for possible future technologies based on...

Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry, said Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and Computer Engineering at Purdue University.Such circuits will require a laser-light source, but current lasers can't be made small enough to integrate them into electronic chips. Now researchers have overcome this obstacle,...

Groundbreaking results published in the premier scientific journal Nature NanotechnologyThe University of Ghent (UGent) and the nano-electronics research center IMEC demonstrated repulsive and attractive nanophotonic forces, depending on the spatial distribution of the light used. These fundamental research results might have major consequences for telecommunication and optical signal processing.Photon impulse is usually considered to be relatively weak. In our macroscopic world, photons...

MOSCOW, March 20 /PRNewswire/ -- A high-tech Photonics exhibition, which is to be held at Expocentre (Moscow) on April 20 - 23, 2009, will include a special section. It will be completely devoted to laser nanotechnologies, which are considerably transforming the image of modern electronics. The emergence of this new section is connected with the beginning of the realization of a large-scale federal program of nanoindustry development in Russia. Photonics appears to be one of the most...

Light-bending metamaterial could lead to superlenses, invisibility cloaksResearchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices.Naomi Halas, an award-winning pioneer in nanophotonics, and graduate student Nikolay Mirin created a material that collects light from any direction and emits it in a single direction. The material uses very tiny, cup-shaped particles called nanocups.In a...

Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines "” when the process is scaled to nano-proportions. Their work opens the door to a new class of semiconductor devices that are...

One of the great challenges in the field of nanotechnology is optical imaging--specifically, how to design a microscope that produces high-resolution images of the nano-sized objects that researchers are trying to study. For example, a typical DNA molecule is only about three nanometers wide--so tiny that the contours of its surface are obscured by light waves, which are hundreds of nanometers long. Now, researchers from Stanford University have greatly improved the optical mismatch between...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
