Craving Bandwidth? Photonics Satisfies
Feb 1, 2013 — Oliver Twist’s plea for “more” was met with incredulity and outrage, but demands by the world’s computer and smartphone users for more bandwidth and greater speed are being greeted with vision, effort and innovation. Optical technologies may hold the key to winning the bandwidth race and to communicating in free space. In our cover story, science writer Valerie C. Coffey says in no uncertain terms that technological developments in photonics are the future of mobile co...
LEDs’ longevity could cause problem for market
Feb 1, 2013 — LEDs are known to last longer than traditional bulbs, but that very trait could actually have a negative effect on the market – after all, if they last longer, they don’t need to be replaced as often. That’s the conclusion of...
Moves & Expansions
Feb 1, 2013 — Southern Photonics of Auckland, New Zealand, has partnered with I-Wave Corp. of Tokyo to provide sales and support to customers in Japan. I-Wave is an importer and exporter of ultrahigh-speed optical transmission and access products. Southern...
People In The News
Feb 1, 2013 — OneChip Photonics of Ottawa, Ontario, Canada, has hired Jonathan Boocock as vice president of product development. He will lead efforts to extend OneChip’s photonic integrated circuit-based passive optical network transceivers and...
Demand for free-space optics devices to grow
Feb 1, 2013 — The global market for free-space optics (FSO) transmitter and receiver link devices used in stationary nonmilitary/aerospace applications registered at $29.83 million in 2012, an increase of 13 percent over 2011, according to a report from...
VC funding for solar drops 50 percent in 2012
Feb 1, 2013 — Venture capitalists (VCs) invested half as much in the solar industry in 2012 as they did the year before, and the overall VC funding for solar reached its lowest point since 2007, according to a January report by clean energy communications and...
NASA “spokeschicken” charms science learners
Feb 1, 2013 — Don’t be fooled by her appearance – Camilla is no ordinary rubber chicken. She’s a social media celebrity, an educator and an inspiration, traveling around the world and even to the edge of space in the name of science. Her full...
Newport’s Photovoltaic Lab offers wafer testing
Feb 1, 2013 — Newport Corp.’s Technology & Applications Center’s Photovoltaic Lab in Irvine, Calif., now offers solar wafer testing and calibration on cells up to 156 x 156 mm. Endorsed by the American Association for Laboratory Accreditation,...
Under One Roof
Feb 1, 2013 — Advanced Thin Films, a unit of Idex Optics & Photonics, has announced that the brands and capabilities for Precision Photonics and ATFilms have fused under one roof. The newly united team will deliver advanced coatings, optical monitoring...
Near-perfect optical absorber developed
CAMBRIDGE, Mass. – A tunable device coated with a film 100 times thinner than the wavelength of incident light absorbs 99.75 percent of a specific mid-infrared band on demand, potentially expanding thermal detection and energy harvesting applications. Designed by...
Theoretical calculation proposes using heat to power QCLs
INNSBRUCK, Austria – Heat generated in a quantum cascade laser (QCL) – something that normally causes the lasing to turn off – could actually be used to power the device instead, according to a theoretical calculation developed at the University of...
Mechanical oscillator transfers optical signals
EUGENE, Ore. – Suppose you needed two PCs to exchange information. The process would be relatively easy because they speak the same language. Between a PC and a Mac, however, you would need a middleman, although that problem is still relatively simple. But what if...
Metamaterials manipulate light on a microchip
UNIVERSITY PARK, Pa. – Controlling light on a microchip is no easy feat, but new theoretical designs for miniaturized optical devices made of metamaterials could make it a little easier. A unified theory from researchers at Penn State University combines metamaterials and...
‘Hyper’ Ramsey excitation confirmed
BRAUNSCHWEIG, Germany – Shining laser light onto atoms and molecules is the best way to obtain precise information about their inner structure, but light above a certain intensity can fundamentally change their energy levels. A group in Germany has demonstrated how to...
Tiny probes dramatically boost Raman signals
ST. LOUIS – Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper...
CERN detector to measure supershort pulses
VIENNA – Conventional measurement techniques soon will be too slow to measure phenomena taking place on timescales faster than an attosecond. To measure such light pulses, scientists have proposed a method to create the world’s most precise stopwatch....
Defying expectations, x-ray laser supercharges atoms
MENLO PARK, Calif. – Using a single flash from the world’s most powerful x-ray laser, researchers have stripped a record number of electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low....
Recipe for supercheap hydrogen: sunlight + water + rust
LAUSANNE, Switzerland – Water and rust can make supereconomical hydrogen from sunlight, a team from École Polytechnique Fédérale de Lausanne (EPFL) reported recently. Researchers have been pursuing the conversion of solar energy into...
Raman researchers set a trap to cool ions
BANGALORE, India, and MAINZ, Germany – Trapping ions with cold atoms cools the ions and could lead to experiments that generate molecular ions at interstellar space temperatures. The traps also can store ions in a stable condition for longer periods than previously demonstrated. Methods...
Photon funnel makes the most of sun’s rays
Feb 1, 2013 — A solar “funnel” exploits materials under elastic strain and could provide a new way of harnessing photons for electricity by capturing a wider spectrum of solar energy. “We’re trying to use elastic strains to produce...
ETOP - Meeting the Future of Global Optics Education
Feb 1, 2013 — Every couple of years, scientists, technicians and educators in optics and photonics come together to discuss and demonstrate the latest approaches to teaching in these fields at ETOP, the International Conference on Education and Training in Optics...
Laser Safety Training: How Much Is Enough?
Feb 1, 2013 — Experts offer practical advice for selecting and scheduling laser safety training. For people who work with lasers – laser safety officers, industrial hygienists, health physicists, environmental health and safety professionals, manufacturing...
