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...
