Paper Abstract

Previously, strain has shown to reduce the threshold current density for long cavity semiconductor lasers. However, also important is the cavity length for which the threshold current has a minimum. We find that for a given well width, an increase of the indium ratio from the lattice-matched value substantially reduces this optimum cavity length. We attribute this to the combined effects of strain on the valence bands and an increase in the confinement of the conduction band electrons to the well.
