Nanolaser RandD Leads To License Deal
Nanosys has taken out an exclusive licence for semiconductor nanowire-based nanolaser technology from the University of California. The research on which the licence was based was conducted by Dr Peidong Yang, Scientific Founder of Nanosys. The lasers were developed by growing zinc oxide (ZnO2) nanowires on sapphire substrates (Science, June 8, 2001). The nanowires form laser cavities with diameters varying between 20-150nm and lengths up to 10microns. In the Science paper, optical excitation resulted in surface emission of laser light with a wavelength of 385nm and a linewidth less than 0.3nm.
Among potential applications envisaged are high density information storage, high definition display, photonics, optical communications and chemical analysis on microchips. This technology could even enable the development of extreme-resolution nano-lithography, the company believes. 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.
Nanosys Founder and Director of Business Development Dr Stephen Empedocles says: "This exclusive license will enable us to pursue near term products such as ultra-high resolution photolithography and laser powered biochips."
