This thesis investigates passively mode-locked semiconductor lasers
by numerical methods. The understanding and optimization of such
devices is crucial to the advancement of technologies such as
optical data communication and dual comb spectroscopy. The focus of
the thesis is therefore on the development of efficient numerical
models, which are able both to perform larger parameter studies and
to provide quantitative predictions. Along with that, visualization
and evaluation techniques for the rich spatio-temporal laser
dynamics are developed; these facilitate the physical
interpretation of the observed features. The investigations in this
thesis revolve around two specific semiconductor devices, namely a
monolithically integrated three-section tapered quantum-dot laser
and a V-shaped external cavity laser. In both cases, the
simulations closely tie in with experimental results, which have
been obtained in collaboration with the TU Darmstadt and the ETH
Zurich. Based on the successful numerical reproduction of the
experimental findings, the emission dynamics of both lasers can be
understood in terms of the cavity geometry and the active medium
dynamics. The latter, in particular, highlights the value of the
developed simulation tools, since the fast charge-carrier dynamics
are generally not experimentally accessible during mode-locking
operation. Lastly, the numerical models are used to perform laser
design explorations and thus to derive recommendations for further
optimizations.
