Abstract

The mode-locking dynamics of a vertical external-cavity surface-emitting laser with saturable absorber is analyzed using a microscopic many-body theory. The light field is treated at the level of Maxwell’s equations and the quantum-wells are modeled using the semiconductor Bloch equations. The carrier relaxation and the polarization dephasing dynamics is treated at different levels of approximation ranging from a simple rate approximation to the second-Born-Markov level. Examples of mode-locked pulse generation are presented identifying the regimes for stable ultra-short pulses, multiple pulse generation, and instability.
