Polariton Laser Is Electrically Injected
An international team led by Stanford University's Yoshihisa Yamamoto demonstrated a revolutionary electrically driven polariton laser that could significantly improve laser efficiency by requiring 100 times less power than conventional lasers. "We're hoping we can replace conventional semiconductor lasers with these polariton lasers in the future," said physicist Na Young Kim, a member of the Stanford team. "There are a lot of hurdles in the way, but we aim to bring novel devices built on sound physical understanding for cost-effectiveness and efficient power consumption. We've solidified our physical understanding, and now it's time we think about how to put these lasers into practice. This is an exciting era to imagine how this new physics can lead to novel engineering." |

Nanoantennas Improve Infrared Sensing
Patterning nanoantennas with “slots” that correspond to wavelengths in the mid-IR yielded a new way to tune IR light into mechanical action, paving the way for more sensitive IR cameras and more compact chemical-analysis techniques, says a team at the University of Pennsylvania. |

Wheels Come Off Planet-hunting Telescope
The wheels have literally come off the Kepler space telescope, NASA’s primary instrument for detecting planets beyond our solar system. Last week's malfunction leaves just two of the four stability-controlling wheels operational, jeopardizing the sun-orbiting spacecraft's continued mission. |

CLEO 2013 - June 9 - 14, 2013 · San Jose, CA
Visit Photonics Media at Booth 2027 |
 |
CLEO, the Conference on Lasers and Electro-Optics, is the premier international forum for scientific and technical optics, uniting the fields of lasers and electro-optics by bringing together all aspects of laser technology, from basic research to industry applications. CLEO 2013 will feature its technical program under three core conferences; CLEO: QELS-Fundamental Science, CLEO: Science & Innovations, and CLEO: Applications & Technology.
The CLEO: Market Focus program focuses on the latest trends in the photonic marketplace, providing a forum to discuss new products and emerging technologies and markets while also providing network opportunities. Presentations for this year include Industrial Laser Outlook and Opportunities, Photonics Entrepreneurs, Medical and Aesthetic Lasers – The Future of Light-tissue Interactions, and Optics & Innovation for Energy & the Environment. Free exhibit floor programs include the Market Focus program, Technology Transfer Showcase, OSA’s Executive Speaker Series and the CLEO: Expo Technology Playground, where top industry players will demonstrate their latest products and services in an exclusive on-floor event that allows attendees to participate in live, interactive presentations.

FEATURED VIDEO
Aerotech - Nmark AGV Galvanometers
Nmark AGV galvanometers use innovative optical feedback technology to increase resolution to greater than 24 bits, compared with the 16 or 20 bits achieved by other high-end scanners for laser micromachining applications. The result is a significant improvement in accuracy: A 100-mm focal length lens has 2-D positioning accuracies of 10 µm or better.
