Abstract :
The purpose of this work is to study the effect of carrier dynamics on quantum-dot laser performance. The simulation using carrier-photon rate equations clarifies criteria on the carrier relaxation lifetime as well as the inhomogeneous broadening linewidth and the crystal quality to achieve high-performance. The relaxation lifetime forms a hierarchy in quantum-dot lasers, i.e., what performance we can expect strongly depends on the relaxation lifetime
