Description:

The discovery of room-temperature ultraviolet nanowire lasers has led into an exciting new area of fundamental research. This research has now expanded into ZnO and GaN based quantum wire lasers. The linewidths, wavelengths, and power dependence of the nanowire emission characterize the nanowires as active optical cavities.  Over the past couple of years, a significant amount of fundamental knowledge has been gained on the nanowire lasing characteristics as well as the effect of the miniaturized optical cavity.  These individual nanolasers could serve as miniaturized light sources for microanalysis, information storage, and optical computing.
