In Situ Method Optimizes Optical Coatings
Nov 1, 2012 — Real-time technology helps manufacturers produce better thin films with less downtime, higher yields and lower costs. From the simplest broadband antireflection coatings used on eyeglasses and camera lenses to the complex coatings used in civilian and military lasers, optical fiber devices and high-brightness LEDs, optical thin films are to be found everywhere. Although we may not be aware of their presence, thin-film coatings enable commercialization and efficient operation of optical device...
Superpolished Optics Enable High-Sensitivity Laser Applications
Nov 1, 2012 — A review of superpolished surfaces, including fabrication and measurement, as well as some of the leading applications that depend on these optics. Superpolished optics – that is, components with subangstrom surface roughness – represent...
Spinach power boosts silicon solar cells
Nov 1, 2012 — Popeye’s muscles get energy-boosting powers extracted from spinach – and now so do solar panels. Combining the vegetable’s photosynthetic protein with silicon produces significantly higher current levels than can be achieved by...
878-MP nightscape image reveals light pollution
Nov 1, 2012 — Bright city lights help us get around more easily at night, but they also can affect nocturnal wildlife, the environment, sleep patterns and more. “I became interested in light pollution because we know so little about it,” said Helga...
Our Continuing Mission …
Nov 1, 2012 — Watching retired space shuttle Endeavour moving through the streets of Los Angeles on its 12-mile trip from LAX to the California Science Center, I couldn’t help but feel a bit nostalgic for the shuttle program. Launched on April 12, 1981,...
Detection market catches fire
Nov 1, 2012 — Laser-based aspirating smoke detectors (ASDs) and multisensor detectors are forecast to see the fastest global growth in the fire detection industry over the next few years, according to IMS Research. The market research company predicts compound...
CVI Laser marks 40th anniversary
Nov 1, 2012 — CVI Laser of Albuquerque, N.M., is marking 40 years of providing thin-film-enabled optical components and subsystems to the semiconductor, life sciences, industrial, aerospace and scientific markets. The company was founded in 1972 to support...
Dark energy camera achieves first light
Nov 1, 2012 — The most powerful sky-mapping machine ever created recorded its first images on Sept. 12. The 570-megapixel Dark Energy Camera (DECam), the main components of which are shown here, was constructed at Fermi National Accelerator Laboratory in Batavia,...

Replacing “consumer electronics” with “consumer photonics”
PHILADELPHIA – Cadmium sulfide nanowires can be used to create an all-optical photonic switch, a team at the University of Pennsylvania said. They combined the switch with others to create a logic gate for on-chip information processing. “Putting switches...
Record pulse provides new tool for observing quantum mechanics
ORLANDO, Fla. – The young field of attosecond science marked a significant milestone recently with the generation of the shortest laser pulse to date – 67 attoseconds. The record, achieved by Dr. Zenghu Chang and colleagues at the University of Central...
Superstable laser could power atomic physics
BOULDER, Colo. – An optical resonator made of single-crystal silicon, a particularly stiff and low-noise material – instead of the traditional glass with its disordered and “soft” material structure – has enabled the creation of a laser so...
Plasmon wave propagates for 80 µm with no diffraction
CAMBRIDGE, Mass. — A needlelike beam of light that propagates for an unprecedented distance of 80 µm without spreading could greatly reduce signal loss for on-chip optical systems and might eventually aid development of more powerful microprocessors. The...
System measures limits of plasmonic enhancement
DURHAM, N.C., and LONDON – Photonic interactions have been measured for the first time on the scale of a single atom. The ability to quantify the unique properties of light gives physicists a road map to precise control of scattering in metal-based devices such as biosensors...
Lasers improved for standoff sensing
EVANSTON, Ill. – A new resonator design that controls both wavelength and beam quality enables the purest, brightest and most powerful beams ever from a single-mode infrared quantum cascade laser. The work improves the accuracy of the devices, critical for boosting...
X-ray, optical wave mix probes light at atomic scale
BERKELEY, Calif. – Mixing x-ray and optical lightwaves enables observations of how light interacts with matter on the atomic scale. The capability can reveal certain properties of matter, and may enable the observation of changes during chemical reactions, such as the...
