Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna that captures light in the same way, at a small scale that has big potential.
Finding ways to control matter at the level of single atoms and electrons fascinates many scientists and engineers because the ability to manipulate single charges and single magnetic moments (spins) may help researchers penetrate deep into the mysteries of quantum mechanics and modern solid-state physics.
Modulight announced today a set of high-power single lateral mode lasers ideal for optical time-domain reflectometer (OTDR) and other metrology applications.
The lasers produce up to 300mW pulsed optical power and cov...
An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers.
Prof. Schattschneider from Vienna University of Technology (TU Vienna), together with colleagues from Belgium, is developing a method of producing rotating electron beams and is publishing the technology in the scientific journal "Nature".
A team of EU-funded scientists has come up with a way of generating rotating electron beams. The technique, described in the journal Nature, could be used to probe the magnetic properties of materials and could even be a...
Now an entire new class of phase-change materials has been discovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley that could be applied to phase change random access memory (PCM) technologies and possibly optical data storage as well. The new phase-change materials – nanocrystal alloys of a metal and semiconductor – are called “BEANs,” for binary eutectic-alloy nanostructures.
Arizona State University’s expanding research, education and entrepreneurial endeavors in photonics engineering and science has led to formation of the Center for Photonics Innovation.
Professor Andrei Rode's team from the Laser Physics Centre at ANU have developed a laser beam that can move very small particles up to distances of a metre and a half using only the power of light.
Whilst the lase...
Behind every coincidence lies a plan - in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be explained in mathematical terms. Researchers at the Max Planck Institute for the Physics of Light in Erlangen have constructed a device that works on the principle of true randomness.
