-
Dubbed a "spaser", this minuscule lasing object is the latest by-product of a buzzing field known as nanoplasmonics.
-
Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry, said Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and Computer Engineering at Purdue University.

The spaser might have remained just a theoretical curiosity.
-
Future work may involve creating a spaser-based nanolaser that uses an electrical source instead of a light source, which would make them more practical for computer and electronics applications.

The "spaser-based nanolasers" created in the research were spheres 44 nanometers, or billionths of a meter, in diameter - more than 1 million could fit inside a red blood cell.

The researchers, however, have overcome this hurdle by using not photons but surface plasmons, which enabled them to create a resonator 44 nanometers in diameter, or less than one-tenth the size of the 530-nanometer wavelength emitted by the spaser.

By analogy with the acronym that produces the word laser, they dubbed their brainchild "surface plasmon amplification by the stimulated emission of radiation" - spaser - and published a paper about it (
