TAU develops a groundbreaking nano-laser for medicine and electronics Lasers have revolutionized the communications and medical industries. They focus light to zap tumors and send digital TV signals and telephone communications around the world. But the physical length of an ordinary laser cannot be less than one half of the wavelength of its light, which limits its application in many industries. Now the Spaser, a new invention developed in part by Tel Aviv University, can be as small as...

Surface plasmons are quanta of collective oscillations of free electrons at metal-insulator interface, usually excited by photons. Since it was first proposed in 1950s by Ritchie, new interests have been aroused due to recent advances in synthesis and fabrica-tion of various nanostructures. Novel optical properties were frequently reported on these materials, with great potential applica-tions in physics, chemistry, biology and cancer therapy, etc. Some of them have even exhibited enormous...

Air Force Office of Scientific Research-funded Professors Mark L. Brongersma of Stanford University and Stefan A. Maier of Imperial College London are investigating new applications for terahertz sensors. Based on their research, these sensors could be used for improving optical sources, detectors and modulators for optical interconnections and for creating biomolecules, such as plastic explosives for the Air Force. Brongersma's work is based on the unprecedented ability of nanometallic or...

With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported. The technology could have applications in the design of micro-electromechanical systems (MEMS) -- nanoscale devices with moving parts -- and micro-optomechanical systems (MOMS) which combine moving parts with...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
