QD Vision, developer of nanotechnology-based solutions for displays and lighting, announced it has achieved significant improvements in brightness, efficiency and lifetime thresholds for its Quantum Light" product platform, advancing its quest to make quantum-dot-based light-emitting devices (QLEDs) deliver best-in-class performance among display technologies.
"These new pictures are instantaneous snap-shots of energy being transported between electrons across a protein. Remarkably, the pictures go further in unravelling the complex way the electrons interact. This gives us something akin to a fingerprint for electronic couplings," says Dr Ian Mercer from the School of Physics at University College Dublin, the lead author of the new study, who is a visiting researcher at Imperial College London.
Innolume, the leading provider of Quantum Dot (QD) laser diodes and modules covering the 1064nm to 1320nm optical spectrum, today announced that it will be presenting a technical paper on its revolutionary comb-laser at Photonics West in San Jose, California January 27th (Paper 7230-21, Session 5: Integration and Devices for Comms, 10:30 AM).
A team of physicists and engineers has demonstrated an optical device that filters two particles of light (or photons) based on the correlations between their polarisation that are only allowed in the seemingly bizarre quantum world. This so called "entanglement filter" passes the pair of photons only if they inhabit the same quantum state, without the user (or anything else) ever knowing what that state is.
For the first time, scientists have successfully teleported information between two separate atoms in unconnected enclosures a meter apart - a significant milestone in the global quest for practical quantum information processing.
The interaction of light and matter has always fascinated physicists and layman as well. Recently a group of researchers led by Dr. W. M. Liu from Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, CAS published their findings on Josephson effect for photons in Physical Review Letters.
Inexpensive solar cells, vastly improved medical imaging techniques and lighter and more flexible television screens are among the potential applications envisioned for organic electronics.
Researchers at Rensselaer Polytechnic Institute have developed and demonstrated a new type of light emitting diode (LED) with significantly improved lighting performance and energy efficiency.
Modern electronics is built upon the control of electric charges through an electric field. Computing based on photons rather than electrons, on the other hand, promises significantly faster computation and information processing. An international team of researchers has now developed a theoretical system that would allow single photons to be controlled reliably.
In 2004 Lyncean Technologies announced the construction of the Compact Light Source (CLS), a miniature synchrotron which uses inverse Compton scattering to produce high-intensity, tunable, near-monochromatic x-ray beams.
