Nanosys Inc. has signed an agreement with The Regents of the University of California for the exclusive license of semiconductor nanowire-based nanolasers developed by the university's research team. The research which led to this breakthrough was conducted by Dr. Peidong Yang, founder of Nanosys.

The lasers were developed by growing semiconductor nanowires which are ten thousand times thinner than a human hair. According to Yang, among the potential applications of this technology are high density information storage, high definition display, photonics, optocommunications, and chemical analysis on microchips. Further, this technology could also enable the development of extreme-resolution nanolithography for next-generation microprocessor fabrication. The laser can be tuned to emit light of different wavelengths from the infrared to the deep ultraviolet by simply changing the diameter or composition of the nanowire.

Nanowire-based lasers represent a dramatic improvement over GaAs and gallium nitride lasers that are today's leading solid state lasers. Current lasers are made of multilayer thin films and are several micrometers in size. The nanowire laser developed by Yang, on the other hand, is about 1,000 times smaller, allowing extremely localized optical illumination.

"At this preliminary stage of development, these nanolasers have great potential to compete with the gallium nitride blue laser in terms of ease of manufacture, brightness, and much smaller dimensions," said Yang.
