Abstract :
Self-consistent optical gain analysis of strain-compensated InGaN-AlGaN quantum wells (QWs) using 6-band kldrp formalism shows 28% improvement, which is suitable for laser active regions. MOCVD-grown strain-compensated InGaN QW exhibited 62.7% improvement in integrated luminescence intensity.
