Room-Temperature Low-Threshold Surface-Stimulated Emission by Optical Pumping from AlGaN/GaN Double Heterostructure

The difference in the refractive index at a wavelength of 370 nm between GaN and AlGaN (x = 0.1) is found to be about 0.19. With use of AlGaN/GaN double heterostructures, the threshold power for surface-stimulated emission by optical pumping at room temperature has been markedly decreased to about one-twentieth that of a bulk GaN layer. The mechanism of the stimulated emission in this system is discused.
