OSA to Launch New Journal
WASHINGTON, DC, June 7, 2010 — The Optical Society (OSA) announced it will launch a new journal devoted to optical materials, called Optical Materials Express (OME). OME will launch in spring 2011 with bi-monthly issues, joining OSA's portfolio of 14 peer-reviewed optics journals. The editor-in-chief is David Hagan, associate dean for academic programs and professor of optics and physics at CREOL, The College of Optics & Photonics at the University of Central Florida. Optical Materials Express will primarily...
Bending Light at will with Transformation Optics
May 10, 2010 — Invisibility cloaks get all the publicity, but they may just be the beginning if the promise of transformation optics can be realized. The discipline could lead to smaller photonic and electronic devices and more cost-competitive solar cells –...
THz Control Could Mean X-Ray Vision
WASHINGTON, DC, May 10, 2010 — Boston University researchers are closing in on making x-ray vision a reality. Led by BU’s Richard Averitt, the team has developed a new way to detect and control terahertz (THz) radiation using optics and materials science. This type of...
‘GRIN on steroids’: New lens uses opaque metamaterials
DURHAM, N.C. – It doesn’t look like a lens; it looks more like a tiny set of Venetian blinds. It’s not even made of traditional lens materials such as highly polished glass or plastic. But a new generation of lenses has the potential to make big changes in radar...
A backward shock wave comes forward
HANGZHOU, China – A group of researchers has demonstrated a reverse photonic shock wave. As a result, high-energy physics could have a new particle detector, and proposed invisibility cloaks already...
New Lens: GRIN on Steroids
DURHAM, N.C., Dec. 21, 2009 -- Engineers created a new generation of gradient index (GRIN) lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail, although what they fashioned looks more like a...
Guiding light is not just a soap opera
BOSTON – Computers of the future may use light rather than electricity for logic functions. “There is this dream of the all-photonic circuit to guide light and perform functions,” commented Willie Padilla, a professor at Boston College. Such light-based...
The Teacher
Oct 1, 2009 — After earning a PhD at Caltech, Nader Engheta spent four years at Kaman Sciences Corp. before joining the faculty at the University of Pennsylvania in Philadelphia, where he is now the H. Nedwill Ramsey Professor of Electrical and Systems...
Broadband Exterior Cloaking
SALT LAKE CITY, Aug. 18, 2009 – A new active cloaking method might someday shield submarines from sonar, planes from radar, building from earthquakes and coastal structures from tsunamis, said a group of mathematicians at the University of Utah.
Guiding Light Revealed
CHESTNUT HILL, Mass., July 31, 2009 – Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern...
Materials Mimic Mechanics
BERKELEY, Calif., July 21, 2009 -- Astronomical phenomena such as black holes could be studied in a tabletop laboratory setting if the nascent field of artificial optical materials is combined with celestial mechanics, researchers say. “We have introduced a new class of specially...
PECASE Funds Photonics Work
WASHINGTON, July 13, 2009 -- Scientists and engineers focused on photonics-related work were among the 100 named by President Barack Obama as recipients of the Presidential Early Career Awards for Scientists and Engineers (PECASE), the highest honor bestowed by the US...
Nano, Solar Top Show Agenda
SAN DIEGO, June 24, 2009 -- New research in nanoengineering, solar, optical engineering and photonics will be presented, and 400 years of telescopes celebrated, at SPIE Optics+Photonics 2009, the most multidisciplinary science and engineering event in North America. The event...

Australians seek to save the planet with photonics
SYDNEY, Australia – Australia’s future has gotten brighter, thanks to the launch of the Institute of Photonics and Optical Science (IPOS) at the University of Sydney – the only one of its kind in the country. The new institute was introduced at the end of April with a...
Cloak has Tapered Waveguide
WEST LAFAYETTE, Ind., May 20, 2009 -- Using a specially tapered optical waveguide instead of exotic metamaterials that require complex nanofabrication, researchers have created a simplified invisibility cloak that, unlike previous ones, works for all colors of the visible spectrum. The...
Closing in on Invisibility Cloak
BERKELEY, Calif., Aug. 11, 2008 – The idea of an invisibility cloak certainly pushes the edge of plausible, however a group of scientists from the University of California, Berkeley, have come one step closer to being able to render objects invisible to the human eye. For the first...
Metamaterials Pioneer to Receive IEEE Award
Jun 2, 2008 — George V. Eleftheriades, PhD, will receive the 2008 Kiyo Tomiyasu Award for his research into negative refractive index metamaterials, IEEE announced today. Metamaterials have had a profound impact on a variety of technologies including high-speed...
METAMATERIALS
May 1, 2008 — An addition to the “Wiley Series in Microwave and Optical Engineering,” the 333-page book Metamaterials with Negative Parameters: Theory, Design, and Microwave Applications is devoted mainly to metamaterials that can be characterized by a negative...
'Trapped Rainbow' Slows Light
GUILDFORD, England, Nov. 15, 2007 -- A new technique proposes using metamaterials that refract light negatively to slow down, stop and capture light in a "trapped rainbow." The work is being called a step toward much faster optical networks and more powerful computers. The technique...
Light Bent the 'Wrong' Way
PRINCETON, N.J., Oct. 15, 2007 -- A new, easy-to-produce material created from semiconductors refracts light negatively, bending the waves in the opposite direction from that taken by all materials found in nature. This unique ability may contribute to significant advances in areas...
100K Dpi Printing Unveiled
ZURICH, Switzerland, Sept. 11, 2007 -- A new technique allows the printing of particles as small as 60 nanometers -- roughly 100 times smaller than a human red blood cell -- in complex patterns at a resolution of 100,000 dots per inch. The level of control offered by the nanoprinting...
Metamaterials a Hot Topic at Optics Congress in Prague
PRAGUE, Czech Republic, April 11, 2007 -- Engineered composites that exhibit exceptional properties not readily observed in nature -- commonly known as metamaterials -- and their potential use in invisibility cloaks, new imaging methods and communication technologies will be a major topic...
