Plasmonic Nanotweezers Keep Cool
CAMBRIDGE, Mass., Sept. 28, 2011 — A new instrument dubbed a plasmonic nanotweezer creates strong forces more efficiently than traditional optical tweezers and eliminates a problem that caused earlier setups to overheat. It may make it easier to isolate and study tiny particles such as viruses.
Bringing a Laser to Life
Sep 22, 2011 — Earlier this summer, Harvard University researchers reported the first successful biological laser based on a single living cell. Malte C. Gather and Seok Hyun Yun, whose backgrounds are in physics, not biology, said they understood that lasers play...
‘Photon Loop’ Sidesteps Defects in Delay Devices
GAITHERSBURG, Md., Aug. 25, 2011 — The dawn of optical fibers a few decades ago made it possible for independent phone conversations to travel long distances across town and even across the ocean along a single glass cable with little interference. So why then, years later, is it so...
Method Lops Years off Organic Semiconductor Development Process
STANFORD, Calif., Aug. 23, 2011 — Imagine if you could roll up an iPad — or any other tablet-esque display — like a yoga mat and tuck it into your back pocket or under your arm for ease of transport. Researchers at Stanford University and at Harvard University in...
Robust Imaging Tool Boosts Biology, Materials Science
EUGENE, Ore., Aug. 8, 2011 — A novel imaging method developed at the University of Oregon may help researchers better understand and predict how nanometer-size pieces fit together into structures ranging from living cells to artificially fabricated devices. Coupling...
Coated Nanowires Boost Photosensitivity
CAMBRIDGE, Mass., July 14, 2011 — By applying a coating to individual silicon nanowires, researchers at Harvard University and the University of California, Berkeley, have significantly improved the materials’ efficiency and sensitivity — a development that holds promise...
Robots and Autopilots Could Use a Bird’s-Eye View
CAMBRIDGE, Mass., July 6, 2011 — New research on how birds can fly so quickly and accurately through dense forests may lead to new developments in robotics and autopilots. Scientists from Harvard University trained pigeons to fly through an artificial forest with a tiny...
Vibrant Colors Created in Si Nanowires
CAMBRIDGE, Mass., April 19, 2011 — Individual vertical silicon nanowires that shine in all colors of the spectrum have been developed that could increase the efficiency of nanoscale image sensors and give them the ability to detect color without the use of filters. “It is...
Telescope Calibration Reveals Universe
GAITHERSBURG, Md., Jan. 25, 2011 — The accelerating expansion of the universe is one of the mysteries plaguing astrophysics, and somewhere in distant galaxies are yet-unseen supernovae that may hold the key. Now, thanks to a telescope calibrated by scientists from the National...
A Pig and a Chicken Open a Diner…
Jan 24, 2011 — Andrew Hargadon has worn many hats over the years. Trained as a mechanical engineer, he found himself in Silicon Valley in the early nineties – he was one of the self-proclaimed “geniuses” working for Apple at the time – and...
Keep Your Friends Close…
Jan 3, 2011 — We all know about advances in communications technologies – from email to Skype, from wikis to document sharing systems. And we know how they facilitate greater inter-institution and even international collaborations between researchers,...
$12.5M Financing Completed
Dec 1, 2010 — Harvard University photonics spinoff SiOnyx Inc. of Beverly, Mass., has completed its $12.5 million series B financing, with laser giant Coherent Inc. of Santa Clara, Calif., as one of its new investors. Based on a laser implant method discovered at...
Cellular and Stellar Images Win Awards
BELFAST, Northern Ireland, Nov. 16, 2010 — Two visually stunning and scientifically captivating entries have won joint first place in the first Andor Insight Awards Scientific Imaging Competition, Andor Technology plc has announced. The winning entries were submitted by David Jess and...
OSA Names 2011 VP
ROCHESTER, N.Y., Nov. 4, 2010 — The Optical Society of America (OSA) announced recently that its members have elected Donna T. Strickland as its 2011 vice president. In addition, three directors at large were also chosen at this year’s election, including Naomi J. Halas or...
Tiny laser: Big challenge
CAMBRIDGE, Mass. – Since the invention of lasers 50 years ago, some scientists have worked to make the new versions bigger and more powerful, while others have been in pursuit of smaller and more efficient models. Now, a group of scientists at Harvard University and...
Research Bridges Light and Smell
COLD SPRING HARBOR, N.Y., Oct. 28, 2010 — Research Bridges Light and Smell COLD SPRING HARBOR, N.Y., Oct. 28, 2010 — A team co-led by neuroscientists at Cold Spring Harbor Laboratory (CSHL) has shed light — literally — on circuitry underlying the olfactory system in...
The French Connection: Optics in France and the US
Oct 8, 2010 — It wasn’t so long ago, at the centuries-old Château Smith-Haut-Lafitte in the Pessac-Léognan appellation south of Bordeaux, that workers had to stand at long sorting tables manually removing pieces of leaves, raisins and other...
Retractions and Besmirched Reputations
Aug 17, 2010 — Saturday morning, a shade before 10am. I’m sipping coffee from a tall mug with stylized lions and tigers and what appear to be cheetahs gracing the outside and wondering what in creation I’m going to write about this week. Feeling a bit...
THz Semiconductor Laser Revealed
CAMBRIDGE, Mass. & LEEDS, England, Aug. 10, 2010 — Applications in terahertz science and technology may be getting a boost thanks to a new terahertz (THz) semiconductor laser that emits beams with a much smaller divergence than conventional THz laser sources. The metamaterial patterns are...
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,...
Optical gain in plasmonic waveguides opens door to subwavelength applications
REYKJAVIK, Iceland – Researchers at the University of Iceland, in collaboration with colleagues at Germany’s University of Cologne and Fraunhofer Institute for Applied Optics and Precision Engineering in Jena, have demonstrated amplified propagation of light in...
UChicago Commits $50M to GMT
CHICAGO, July 23, 2010 — The University of Chicago will provide millions of dollars to the Giant Magellan Telescope (GMT) project, joining an effort to build the world’s largest telescope. The GMT, to be built in Chile, is set to eclipse the image quality even of the...
Plasmonic Amplifier Demonstrated
REYKJAVIK, Iceland, June 2, 2010 — In an important breakthrough in the field of plasmonics, researchers led by Kristjan Leosson and Malte Gather of the University of Iceland have demonstrated net optical amplification in a plasmonic waveguide. Optical amplification is the only...
