Abstract :
The emission-state dynamics of a strongly spectrally inhomogeneously broadened two-section InAs/InGaAs quantum dot (QD) laser are experimentally investigated by exploiting a resistor-SEED configuration and by reverse biasing the absorber. By joining these operation regimes for the first time, a combined and complete understanding of the two-state carrier dynamics including a photon pumping process in mode-locked operation is obtained.
