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,...

RANCHO SANTA MARGARITA, Calif., Aug. 10 /PRNewswire/ -- Most of human history has witnessed people living and working outdoors during the light of day, absorbing "life-charging" full-spectrum solar energy from the sky. An average of 10 hours daily in the sunlight, 70 hours weekly, was common for eons. Now, however, in less than a mere two hundred years, millions of people have unwittingly become "contemporary cave-dwellers," living and working indoors, sometimes, all day long. In...

BIRMINGHAM, N.J., July 31 /PRNewswire/ -- Photon Technology International (PTI), a known innovator in fluorescence with over 26 years of experience is once again expanding the frontiers of detection to attomolar levels with its new QuantaMaster(TM) 40 Spectrofluorometer. While typical spectrofluorometers struggle with picomolar (10(-12))( )detection, which is already a very tiny amount, the new PTI system can now detect attomolar (10(-18)) amounts, allowing it to detect six orders of...

A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists had never been able to confirm, or measure, this breakdown in practice. For the first time, however, MIT researchers have achieved this feat, and determined that the heat transfer can be 1,000 times greater than the law predicts.The new findings could lead to significant new applications,...

Scientists at MIT have figured out a key step toward the design of quantum information networks. The results are reported in the July 20th issue of Physical Review Letters and highlighted in APS's on-line journal Physics (physics.aps.org). A quantum network "“ in which memory devices that store quantum states are interconnected with quantum information processing devices "“ is a prototype for designing a quantum internet. One path to making a quantum network is to map a light...

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...

For more than 100 years it has been known that light comes in small packages, the so-called photons. The discovery of this quantization of the light field has opened up a new field of physics - quantum optics. In the sixties one of its pioneers, the Nobel Prize winner Roy Glauber, suggested to characterize light sources according to the sequence of their emitted photons. But the realization of this idea has been very limited up to now. In modern lasers the light emission can take place within...

European scientists say they have built the world's largest quantum key distribution network to transmit secure quantum encrypted information. Officials said 41 research and industrial organizations constructed the eight-node, mesh network consisting of an average 12-mile to 19-mile link, with the longest link being 51 miles. The scientists said their achievement is a huge step toward practical implementation of secure quantum-encrypted communication networks. The Institute of Physics in...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
