Abstract

Quantum Dot and Quantum Dash Fabry Perot lasers can give wide optical comb spectra with large number of modes stable phase locked. After group delay dispersion compensation, pulses are also obtained. We report, for the first time using a TDTW approach, the simulation of the mode dynamics and of the pulse generation in single-section QD lasers. We have found that the mode dynamics is dominated by four wave mixing and by the coupling induced by the carrier gratings due to spatial hole burning; the width of the optical spectrum is very dependent by the gain compression factor parameter.
