Abstract
Temporally resolved longitudinal mode dynamics for sixfold stacked short cavity quantum-dot lasers is investigated in the μs time range. Results are presented for 10, 20, and 50 μm wide stripes at room temperature and at 100 K. After turn-on a redshift of single longitudinal modes, a blueshift of the mode groups and a redshift of the mean value of the spectra are observed simultaneously. Temperature dependent leakage loss spectra due to leaky substrate modes are calculated. The blueshift of the mode grouping, predicted by the theory, is in good agreement to the experimental data.Keywords
