Using a special hollow-core photonic crystal fibre, a team at the University of Bath, UK, has opened the door to what could prove to be a new sub-branch of photonics, the science of light guidance and trapping.
Professor Ortwin Hess, his PhD student Kosmas Tsakmakidis of the Advanced Technology Institute and Department of Physics at the University of Surrey and Professor Alan Boardman from Salford University have revealed a technique which may be able to slow down, stop and capture light.
Scientists are closer to developing novel devices for optics-based quantum computing and quantum information processing, as a result of a breakthrough in understanding how to make all the spins in an ensemble of quantum dots identical.
A team from Kyoto University has demonstrated a method for dynamically changing the lifetime of a photonic crystal resonator, which in effect can trap a pulse of light inside the system. Susumu Noda and his colleagues showed that the Q factor of their system, a measure of the number of time periods of light after which most of the light has left the system, could be increased by a factor of four from 3,000 to 12,000 within just a few picoseconds.
Thermo Fisher Scientific Inc., the world leader in serving science, announces a strategic partnership with Phytronix Technologies, a Canada-based company, for the use of Laser Diode Thermal Desorption (LDTD) technology.
Using an existing technique in a novel way, Cornell physicist Keith Schwab and colleagues at Cornell and Boston University have made the scanning tunneling microscope (STM) -- which can image individual atoms on a surface -- at least 100 times faster.
Quantum cryptography was used in a real-world application for the first time when the Swiss went to vote in their national elections last week. A quantum key distribution (QKD) system protected the dedicated line that transmitted the ballots to the counting station, guaranteeing the secrecy and security of the data.
Intense Ltd., the developer of next generation semiconductor lasers, recently announced the Intense-HPD Series 6100, 980nm high power single emitter laser diodes. The 6100 Series are very high brightness, single mode lasers with up to 200mW of kink-free power. They provide high beam quality with low astigmatism and a Gaussian far field.
The Sabreen Group, Inc. announces its Patent Pending VectorJet™ Laser Marking Technology that achieves unprecedented “dark-on-light” contrast, line edge detail, and marking speed on Acetals, and many more plastics that have traditionally been difficult, if not impossible, to laser mark.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a new component, known as a superconducting quantum-computing cable, for potential ultra-powerful computers of the future.
