Abstract
The self-consistent model has been used to simulate an operation of the 1.3 -mum GaAs-based quantum-dot (QD) In(Ga)As/GaAs laser. An impact of the QD density and uniformity on laser operation characteristics has been discussed. Performance of oxide-confined (OC) and proton-implanted (PI) VCSELs has been compared and their optimal structures have been analysed. Lasing thresholds of PI VCSELs have been found to be lower at room temperature than those of OC VCSELs but, at higher temperatures, this relation becomes inverted.
