Lasers Manufactured the Size of a Virus Particle

Laser the Size of a Virus Particle: Miniature Laser Operates at Room Temperature and Defies the Diffraction Limit of Light

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.
