Paper Abstract

Staggered InGaN quantum wells (QWs) are analyzed as gain media for laser diodes to extend the lasing wavelength towards 500 nm. The calculation of band structure is based on a 6-band k•p method taking into account the valence band mixing, strain effect, and spontaneous and piezoelectric polarizations as well as the carrier screening effect. Staggered InGaN QWs with two-layer and three-layer step-function like In-content InGaN QWs structures are investigated to enhance the optical gain for laser diodes emitting in the green regime.
