Plasmonic Whispering Gallery Microcavity Paves the Way to Future Nanolasers
January 23, 2009
The principle behind whispering galleries--where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber--has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultra-small lasers, i.e., nanoscale, promise a wide variety of intriguing applications, including super-fast communications and data handling (photonics), and optical microchips for instant and detailed chemical analyses.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
