BERKELEY, Calif, June 6, 2014 — Doping graphene with boron nitride may be a way to tame the material, introducing a bandgap and making it useful in electronic devices. However, controlling the electrical properties of graphene boron nitride (GBN) heterostructures has been tricky....
4 Photonics Projects Get Defense Funding
WASHINGTON, June 3, 2014 — The U.S. Department of Defense has awarded funding totaling $28.3 million for four photonics graduate research projects under its Multidisciplinary University Research Initiative (MURI). Brief summaries of the projects follow. For further...
Laser Sensing for Self-Driving Cars, 3-D Video Games
BERKELEY, Calif., May 30, 2014 — Self-driving cars that could detect nearby objects and people. Answering your smartphone by waving a hand from across the room. 3-D video games that could be played literally anywhere. All of this could be possible with a new 3-D laser imaging...
Nanosphere-Laced Polymer Changes Color Under Stress
RIVERSIDE, Calif., May 23, 2014 — A plastic film that changes color under stress could provide more detailed information in product safety testing and other areas where pressure and strain are measured. A lab at the University of California, Riverside, used a self-assembly method to...
Celestial light switch reveals lunar ranging data
May 5, 2014 — When certain members of the universe play a linear game of hide-and-seek, humans pay attention: Many don special solar glasses; others stay up late to catch sight of a burnt-orange moon. Solar and lunar eclipses are sights to behold, appearing just...
Bug Sensors Could Slow Infection, Defend Crops
RIVERSIDE, Calif. and SAO PAULO, Brazil, May 1, 2014 — Better classification of insects in the wild could be a key to protecting crops and halting the spread of diseases. A team from the University of California, Riverside, in collaboration with the University of Sao Paulo and ISCA Technologies, has...
Semiconductor Manipulates IR Light
SANTA BARBARA, Calif., April 11, 2014 — Enhanced imaging, energy efficiency and telecommunications are among applications that could benefit from the creation of a unique compound semiconductor.
Gold Material Cuts Glare, Repels Water
IRVINE, Calif., April 7, 2014 — An accidental discovery has scientists looking at light glare through new eyes.
Shrink Wrapping Disease Biomarkers
IRVINE, Calif., March 21, 2014 — A new technique for better detection of infectious disease biomarkers has scientists looking at ordinary shrink wrap in a whole new way.
IQE, UCSB Team Up to Grow Silicon Photonics
CARDIFF, England, and SANTA BARBARA, Calif., March 13, 2014 — A new epitaxial wafer technology is moving forward the next generation of quantum dot lasers on silicon substrates.
A Sticky Approach to Fighting Infection
BERKELEY, Calif., March 6, 2014 — A new nanoscale approach to studying a common source of infection could ultimately lead to the creation of bacteria-resistant materials as a line of defense.
New Devices Could Realize Optical Microprocessing
WASHINGTON, Feb. 20, 2014 — The future of computing may lie in photonic devices, specifically microprocessors that use light rather than electric signals.
Better Lasers, Better Computing
Feb 13, 2014 — To take communications to the next level, laser technologies must improve in terms of cost, efficiency and robustness. Fortunately, those improvements are in the works. Whether traveling through free space or over a fiber, lasers power data delivery...

Nov 1, 2013 — The evolutionary chemical machinery of nature – plus a dash of human ingenuity – has inspired synthetic light-harvesting antennas that convert sunlight into unprecedented amounts of usable energy. Light-harvesting antennas are normally...
Space Lasers Set to Protect Earth, Project Data
Nov 1, 2013 — From obliterating asteroids to nudging space trash, lasers in space are becoming every bit as futuristic as they sound. Lasers in space have long been a science-fiction writer’s delight, but with current projects such as LightForce and DE-STAR...
Bioengineers Aim for ‘Visual Cortex on Silicon’
UNIVERSITY PARK, Pa. & SAN DIEGO, Sept. 20, 2013 — A multi-institutional group aims to create a machine vision system that approaches the cognitive abilities of the human brain. Such a system would enable computers to not only record images, but also to understand visual content at up to a thousand...
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...
