With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent.

 | Berkeley Lab researchers at the Molecular Foundry have created bowtie-shaped antennae that function as the first tunable nano color sorters, able to capture, filter and steer light at the nanoscale. ...> Full Article |
 | Researchers at the California Institute of Technology have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. "This is a whole new concept," notes Oskar Painter, associate professor of applied physics at Caltech. Painter is the principal investigator on the paper describing the work, which was published in the online edition of the journal Nature. ...> Full Article |
Researchers have created the tiniest laser since its invention nearly 50 years ago, paving the way for a host of innovations, including superfast computers that use light instead of electrons to process information, advanced sensors and imaging.

The laboratory Structure -- Activity of Normal and Pathologic Biomolecules-Inserm, in collaboration with the Material Center of Mines-ParisTech, the NRG-UMR 5060 CNRS/UTBM and the Physic Institute of Stuttgart University, discovered a novel route to fabricate fluorescent nanoparticles from diamond microcrystals. Results are published in Nanotechnology's June 10 issue.

 | For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called "blinking," but now scientists at the University of Rochester have uncovered the basic physics behind the phenomenon, and along with researchers at the Eastman Kodak Company, created a nanocrystal that constantly emits light. ...> Full Article |
UCLA physicists have created the world's smallest incandescent lamp using a filament made from a single carbon nanotube only 100 atoms wide. Invisible to the untrained eye, the filament appears as a tiny point of light when the lamp is turned on. Even with the best optical microscope it is only just possible to resolve the nanotube's nonzero length. The team uses an electron microscope capable of atomic resolution to image the filament's true structure.
