Abstract
A high characteristic temperature with To of 126 K under continuous-wave operation is obtained for an InAs/GaAs quantum dot laser. A triple-stacked active region with an energy separation of 95 meV between the ground and first excited radiative transitions is used to achieve a ground state saturation gain at 300 K of 13 cm-1, and high internal quantum efficiency of 74%.Keywords
