Paper Abstract

Dynamic effects in a quantum dot (QD) laser are studied theoretically. The frequency and decay rate of relaxation oscillations, and the modulation response are calculated as functions of injection current density, cavity length, and parameters of the QD structure. The highest possible bandwidth is calculated and shown to increase with increasing overlap integral between the electron and hole wave functions in a QD, number of QD-layers and surface density of QDs in a layer, and with reducing QD-size dispersion.
