Nanolaser RandD Leads To License
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 licence will enable us to pursue near term products
such as ultra-high resolution photolithography and laser powered biochips."
