Optical gain analysis of c-InGaN quantum wells on unstrained c−In 0.31 Ga 0.69 N templates

We investigate the optical properties of c−In x Ga 1−x N (x = 0.31–0.44) quantum wells (QWs) on unstrained c−In 0.31 Ga 0.69 N templates in the green-to-red spectral range using self-consistent multiband k⋅p theory. The transverse-electric- and transverse-magnetic-polarized optical gains are much higher for QWs on unstrained c−In 0.31 Ga 0.69 N templates compared with conventional templates because of a smaller internal electric field and strong valence band mixing. Using c−In x Ga 1−x N QWs on c−In 0.31 Ga 0.69 N templates is expected to reduce the threshold carrier density in the green range and extend the operable wavelength into the red range.     «
