LOS ALAMOS, N.M., June 11, 2013 — A single short-pulse laser-driven neutron source could make searching for nuclear materials smuggled in shipping containers much easier, an international experiment has demonstrated.
Optical ‘Antenna-in-a-Box’ Catches Single Molecules
BARCELONA, Spain, June 11, 2013 — An optical “antenna-in-a-box” capable of detecting and sensing individual molecules at high concentrations could provide a better understanding of biological and biochemical reactions to detect early stages of disease.
Alfano Awarded Laser Science Prize
NEW YORK, June 10, 2013 — Robert Alfano, distinguished professor of science and engineering at The City College of New York, has been awarded the 2013 Arthur L. Schawlow Prize in Laser Science by the American Physical Society (APS).
Device Bridges Optomechanics, Microfluidics
URBANA, Ill., June 10, 2013 — Whispering galleries — circular spaces beneath a dome that capture and amplify sound as quiet as a whisper — have inspired numerous scientific discoveries over the past several years. Now the phenomenon, discovered more than a century ago, has been...
CLEO Presents Cutting-Edge Research on Optics, Lasers
SAN JOSE, Calif., June 7, 2013 — Smartphone-based cancer detection, a telecom-based time cloak and UV-LEDs that slow food rot are just a few of the cutting-edge applications of optics and lasers that will be discussed next week at CLEO: 2013, the Conference on Lasers and...
Metamaterial Flexible Sheets Could Transform Optics
LOS ALAMOS, N.M., June 7, 2013 — A new metamaterial design that aims to replace bulky optical devices could improve IR thermal cameras, energy harvesting, and security screening and radar systems.
Firefighter Robot Paints 3-D Thermal Imaging Picture for Rescuers
SAN DIEGO, June 6, 2013 — An image processing technique that allows small Segway-like robotic vehicles to create 3-D thermal images of burning buildings in real time could help firefighters better assess structures and plan rescue missions.
Xenon Adds 3 Labs to Printed Electronics Test Network
WILMINGTON, Mass., June 6, 2013 — Pulsed light technology provider Xenon Corp. has announced that three laboratories have joined its Printed Electronics Test Center Network, bringing the total of participating labs to 25 worldwide.
’Temporal Cloaking’ for Communications
WEST LAFAYETTE, Ind., June 5, 2013 — An alternative “temporal cloaking” method that uses standard optical communications components has improved the time available for secure data transmission to nearly 46 percent, allowing digital data to be concealed at rates that could thwart...
Light-Controlled Gel Could Benefit Soft Robots
BERKELEY, Calif., June 4, 2013 — Inspired by the way plants grow toward light sources, bioengineers at the University of California, Berkeley, created a hydrogel that flexes in response to near-IR laser light. The achievement could be a step toward adding softness and flexibility...
Printing Innovations Improve Organic Electronics
MENLO PARK, Calif., June 4, 2013 — A printing technique that focuses on the physics of the process rather than the chemical makeup of the semiconductor provides a tenfold improvement in organic electronics. The findings could yield flexible electronic displays, tiny sensors and...
Same-Energy Electrons Pulsed from Laser Accelerator
GARCHING, Germany, June 3, 2012 — Electron pulses — all with nearly the same tunable energy — have been produced from a laser accelerator. The accomplishment makes electrons, which travel at a velocity close to the speed of light, easier to control as a tool for...
‘Metascreen’ forms ultrathin invisibility cloak
AUSTIN, Texas – A new invisibility cloak can hide 3-D objects from microwaves while in their natural environment, in all directions and from all of the observers’ positions. Most invisibility cloaks up to this point have been large, cumbersome...
Atoms hollowed by laser form novel plasma
YORK, England – A highly unusual plasma composed of hollow atoms has been created using one of the world’s most powerful lasers. The surprising result shows that a little-explored region of physics is now accessible through the unprecedented intensities being...
Efficiency record set in ultrahigh-speed communications
YORKTOWN HEIGHTS, N.Y. – Ultrafast supercomputers that operate at speeds 100 times faster than current systems may now be one step closer to reality, thanks to researchers at IBM working on a DARPA-funded program. They transmitted massive amounts of data with...
Electronic chips heal after laser blasts
PASADENA, Calif. – A new self-healing integrated chip could recover in microseconds from problems ranging from low battery power to total transistor failure. Engineers at California Institute of Technology demonstrated this self-healing capability in tiny power...
FAMOS aims to make OCT light sources more compact
VIENNA – Optical coherence tomography light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening). ...
Flex-grid prevents network traffic jams
BARCELONA, Spain – A flexible-grid system that controls connections in optical networks can also redirect traffic to other networks, avoiding gridlock. Similar to how services like Google Maps use algorithms to determine the fastest route from point A to point...
Glasses-free 3-D could be coming to a mobile display near you
PALO ALTO, Calif. – While developing optical interconnect technology, engineers at Hewlett-Packard Laboratories realized what they had created could be much more: a multiangle, glasses-free 3-D display technology for mobile devices. Dr. David Fattal is a member of...
Landmark Ireland research investment includes photonics
DUBLIN – The largest-ever state/industry co-funded scientific research investment in Ireland – €300 million – includes millions to establish a large-scale research center devoted to advancing photonics and biomedical science. The...
Metamaterials observe photonic spin Hall effect
BERKELEY, Calif. – A metamaterial surface constructed of V-shaped gold nanoantennas was used to obtain the strongest signal yet of the photonic spin Hall effect – a quantum mechanical optical phenomenon that could play a prominent role in the future of...
New metamaterials are easily manufactured
UNIVERSITY PARK, Pa. – By combining theory and practice, two groups of Penn State scientists have designed low-loss optical metamaterials that are easily manufactured for custom applications with dispersions that can be tuned over large bandwidths. Designing...
Novel use of EMCCD sharpens images
DALLAS – Sharper microscopic images may be in sight with a new method that uses standard low-light electron multiplying CCD (EMCCD) cameras in a new way to reduce noise and minimize image deterioration. Conventional imaging can add electronic noise,...
Plasmonics help ‘bulk’ silicon emit visible light
PHILADELPHIA – A commonly used form of silicon has been made to emit broad-spectrum, visible light, but challenges remain before it can form practical electronic-photonic devices. As engineers move ever closer to the limits of electronic circuits, light is...
