Keep conditions right for invention
Jul 1, 2012 — High achievement always takes place in the framework of high expectation. – Charles F. Kettering, inventor of the electric starter Contemplating the many contributions of Elias Snitzer, whose pioneering work in glass lasers helped bring about a communications revolution, made me wonder about the atmosphere prevalent in his day that supported such discovery. Were expectations high? Was there a sense of competition? Was invention rewarded and protected? Snitzer, who died May 21 at...
Something in the air
Jul 1, 2012 — The recent article on airglow (“The Night Glows Brighter in the Near-IR,” April 2012) contains misleading statements and a generally sloppy treatment of radiometric units of measure. Some behind-the-scenes math by the authors and more...
Single nanomaterial yields a laser rainbow
PROVIDENCE, R.I. – Nanocrystals that produce red, green and blue laser light from a single material could lead to digital displays and other devices that employ a variety of laser colors simultaneously. Red, green and blue lasers have become small and cheap...
Coupled lasers cancel each other out
VIENNA – The discovery that coupling two microlasers shuts them both off instead of emitting more light could prove significant for technologies that combine electronics and photonics. The “laser blackout” effect, discovered by scientists at...
Solar cell-like implant stimulates optic nerve
STANFORD, Calif. – A new retinal prosthesis that uses technology similar to that found in solar cells could restore sight to those who suffer from degenerative eye diseases such as macular degeneration and retinitis pigmentosa. Researchers at Stanford University...
Laser creates cheaper free-form optics
AACHEN, Germany – A new process for fabricating small batches of nonspherical glass optical components will allow manufacturers to produce high-quality, customizable optical components of any geometry quickly and inexpensively. High-speed laser ablation of fused...
Single entangled photon creation unlocked
ATLANTA – A new technique can produce single photons with specific properties more efficiently and about 1000 times faster than the current methods, an important advance for several research areas, including quantum information processing and quantum network...
Release process holds promise for GaN semiconductors
TOKYO – Nitride semiconductors grow only on certain surfaces, and their utility is limited by the substrate on which they are fabricated. But a new release process not only makes the method cheaper and easier, it also expands the potential uses of the...
Students’ QDs win regional Cleantech Challenge
SALT LAKE CITY – Students at the University of Utah recently won $100,000 and first place in the regional CU Cleantech New Venture Challenge for their quantum dot technology. Compared with other materials, quantum dots require less energy for emitting light....
Four-wave mixing generates superluminal pulses
GAITHERSBURG, Md. – A novel four-wave mixing technique that restructures parts of light pulses to travel faster than the speed of light could improve the timing of communications signals and help examine the propagation of quantum correlations. Einstein’s...
Gamma ray refraction could launch nuclear photonics
GRENOBLE, France – An experiment in which gamma rays were bent like ordinary light overturns decades of theoretical predictions and opens the door to a new field of research called nuclear photonics. Gamma rays are essentially a highly energetic form of light....
First heralded single photon generated from silicon
SAN DIEGO – For the first time, a heralded single photon has been generated from a silicon chip. The discovery – made by a consortium of researchers from the University of California, San Diego, the National Institute of Standards and Technology...
Software gives photonics designers more power
GHENT, Belgium – A new open source software platform will offer greater power and flexibility to designers of photonic components and complex photonic integrated circuits. IPKISS, developed by Ghent University and nanoelectronics research center Imec of...
LME 2012 expands educational offerings
SCHAUMBURG, Ill. – Editor’s note: This article was originally published in the May/June issue of LIA Today. LIA has unveiled an expanded educational track for LME 2012, bringing more basic courses and a pair of two-hour tutorials addressing welding and...
Idex Buys Precision Photonics
Jul 1, 2012 — Idex Corp. of Lake Forest, Ill., has acquired optical components maker Precision Photonics Corp. (PPC) for $20 million in cash. PPC was founded in Boulder, Colo., in 2000 by scientists-turned-engineers from the neighboring NIST and JILA research...
MetaStable Instruments Awarded Patent
Jul 1, 2012 — MetaStable Instruments Inc. of St. Peters, Mo., has received US Patent No. 8,139,234 for a technique that measures very low absorption in certain thin-film optical coatings that are deposited in a vacuum chamber. The technique, which helps coaters...
