Abstract
Band‐structure analysis using the tight‐binding method indicates that there is a significant dependence of lasing properties of GaAs/AlGaAs quantum well lasers on substrate orientation, which suggests the importance of choosing the substrate orientation carefully for improving lasing properties. These results are mainly due to changes in the in‐plane effective mass of the heavy hole.Keywords
