Tiny Optics Continue to Roll Forward
Jul 13, 2011 — Individually micro-optics are a few millimeters in diameter at best, but together these tiny lenses comprise a powerful link to future technologies that will affect everything from advanced computers to human health.
QUEST Begins for Improved Electromagnetic Manipulation
LONDON, July 8, 2011 — Becoming invisible with the swish of a cloak or bringing cell phone coverage to previously unreachable places could soon be a reality with a £4.5 million ($7.22 million) project led by Queen Mary, University of London. The project,...
“Carpet cloak” hides more than its size implies
LYNGBY, Denmark – Optical cloaking is getting a boost from metamaterials in a new technology called “carpet cloaking,” which can conceal a much larger area than other cloaking techniques of comparable size. The new carpet cloak, based on an...
Terahertz invisibility cloak created
EVANSTON, Ill. – A new cloaking material can render objects invisible in the terahertz range. While the design does not create an invisibility cloak for the visible spectrum, it could have applications in diagnostics, security and communications. The cloak,...
1-Atom-Thick Optical Devices Proposed
PHILADELPHIA, June 13, 2011 — One-atom-thick metamaterials that can be achieved by controlling the conductivity of sheets of graphene have been proposed by two University of Pennsylvania engineers. Professor Nader Engheta and graduate student Ashkan Vakil, both of the...
Plasmonics May Hold Key to All-Optical Chips
Jun 9, 2011 — A rapidly growing branch of physics promises all-optical computer chips and ultrafast computing speeds. Plasmonics, also called “light on a wire,” exploits the nanoscale interaction of light and metal and is a focus of research in the...
Simplified superlens captures IR light
BERKELEY, Calif. – Superlenses that are ideal for capturing light in the mid-infrared range now can be fabricated more easily. Made from perovskite oxides rather than metamaterials, these new devices could open the door to highly sensitive biomedical detection and...
‘Carpet Cloak’ Hides More Than its Size Implies
LYNGBY, Denmark, May 3, 2011 — Optical cloaking, the ability to conceal small objects by bending and channeling light around them, is getting a boost from metamaterials in a new technology called “carpet cloaking,” which can conceal a much larger area than other...
New Metamaterials Center to Focus on Solar Energy, Sensors
NEW YORK, April 15, 2011 — A new industry and university cooperative research center proposes to provide a one-stop shop for the design, fabrication and testing of a wide range of metamaterials designed to aid solar photovoltaic systems, specialized light sensors and more. ...
Acoustical Waves Tapped for Metamaterials
LOS ALAMOS, N.M., April 7, 2011 — A very simple benchtop technique that uses the force of acoustical waves to create a variety of 3-D structures will benefit the rapidly expanding field of metamaterials and its myriad applications. Metamaterials are artificial materials...
Simplified Superlens Captures IR Light
BERKELEY, Calif., March 31, 2011 — Superlenses fabricated from perovskite oxides are simpler and easier to fabricate than metamaterials and are ideal for capturing light in the mid-infrared range, potentially opening the door to highly sensitive biomedical detection and imaging, say...
Broadband Light Slowed via Nanoplasmonics
BETHLEHEM, Pa., March 22, 2011 — Plasmonic structures can slow light waves over a broad range of wavelengths, verifying the “rainbow” trapping effect, which had been predicted only recently in the theoretical studies of metamaterials. An experiment conducted by...
Optoelectronics Center Buys Nanopatterning Instrument
CHICAGO, March 2, 2011 — The Optoelectronics Research Center has purchased the DPN 5000 System from Illinois-based NanoInk. The instrument will be used for fabricating nanostructured photonic metamaterials and sensors. The Optoelectronics Research Center is based at...
Optical materials go designer
AMES, Iowa – Advances in fabrication technologies could one day lead to superlenses and other designer optical materials. Scientists at Iowa State University and at Karlsruhe Institute of Technology in Germany are studying exotic man-made materials designed to...
The Slow-Light Race Is On
Feb 1, 2011 — Since the notion of slow light first became a reality more than a decade ago, scientists have been exploring its use in fundamental studies of light-atom systems as well as for long-term applications in all-optical data processing, quantum...
Optical Materials Going Designer
AMES, Iowa, Jan. 6, 2011 — Advancements in fabrication technologies may lead to superlenses and other designer optical materials, according to an Iowa State University and Ames Laboratory physicist. In an article titled “Improving Metamaterials” published in...
Metamaterials Research: ‘Project Squid Skin’
HOUSTON, Dec. 29, 2010 — Nanotechnologists, marine biologists and signal-processing experts from Rice University, the Marine Biological Laboratory in Woods Hole, Mass., and other US universities have won a $6 million grant from the Office of Naval Research to unlock the...
Metamaterials Mimic Optical Möbius Symmetry
BERKELY, Calif., Dec. 28, 2010 — After years of searching, scientists have discovered Möbius symmetry in metamaterials – materials engineered from artificial "atoms" and "molecules" with electromagnetic properties that arise from their structure rather than their...
Light-Amplifying Metamaterial Created
WEST LAFAYETTE, Ind., Aug. 4, 2010 — Researchers have overcome a fundamental obstacle in using new "metamaterials" for radical advances in optical technologies, including ultrapowerful microscopes and computers and a possible invisibility cloak. The metamaterials have been...
New Invisibility Cloak Made of Glass
HOUGHTON, Mich., Aug. 2, 2010 — From Tolkien’s ring of power in “The Lord of the Rings” to Star Trek’s Romulans, who could make their warships disappear from view, from Harry Potter’s magical cloak to the garment that makes players vanish in the...
Building with optical Legos
HOUSTON – Just as generations of children have enjoyed stacking and building with plastic Lego toys, scientists are now using light-activated nanoshells as Lego-like building blocks for both 2- and 3-D structures that could be used in chemical sensors,...
Solar, Optics, Nano Addressed at Optics + Photonics 2010
SAN DIEGO, July 16, 2010 — Detailing the latest research and technologies for enabling better care of our environment, our communities and the planet, SPIE’s Optics + Photonics 2010 will take place August 1-5 at the San Diego Convention Center in San Diego. With access...
Transformation Optics Makes a U-turn
BERKELEY, Calif., July 7, 2010 — In transformation optics, light waves can be controlled at all lengths of scale through the unique structuring of metamaterials, composites typically made from metals and dielectrics — insulators that become polarized in the presence of an...
Prime Photonics, Subsidiary to Merge
BLACKSBURG, Va., July 2, 2010 — Prime Photonics LC announced that it will merge with its subsidiary, Prime Research LC, effective immediately. The new entity will operate under the name Prime Photonics LC. The consolidation is not expected to impact any of Prime...
A new twist on moving matter with light
ANN ARBOR, Mich. – Light can bend rigid structures, at least on a microscopic scale, researchers report. Light-driven twisting of tiny ribbons could someday be used for negative refractive index materials, in microelectromechanical systems (MEMS), or for lithography...
