Abstract :
Using an optimized delay-differential-equation model, we efficiently simulate the signal propagation through a quantum-dot semiconductor amplifier. We analyze the device performance by means of the signal quality factor when amplifying signals on either the ground or excited state transition, in dependence of pump current and signal power.
