Laser the Size of a Virus Particle created

ScienceDaily (Nov. 5, 2012) A Northwestern University research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.

Reducing the size of photonic and electronic elements is critical for ultra-fast data processing and ultra-dense information storage. The miniaturization of a key, workhorse instrument -- the laser -- is no exception.

The results are published in the journal Nano Letters.

"Coherent light sources at the nanometer scale are important not only for exploring phenomena in small dimensions but also for realizing optical devices with sizes that can beat the diffraction limit of light," said Teri Odom, a nanotechnology expert who led the research.
