Additional experiments and the use of more sophisticated models, incorporating background noise, the microcavity of the EP-VECSEL [12,45], and third-order-dispersion [13] are required to further improve understanding of the pulse dynamics and the transformation of FM-type mode-locking to AM pulse trains.…”

Self-starting pulsed operation in an electrically pumped (EP) vertical-external-cavity surface-emitting-laser (VECSEL) without intracavity saturable absorber is demonstrated. A linear hemispherical cavity design, consisting of the EP-VECSEL chip and a 10% output-coupler, is used to obtain picosecond output pulses with energies of 2.8 pJ and pulse widths of 130 ps at a repetition rate of 1.97 GHz. A complete experimental analysis of the generated output pulse train and of the transition from continuous-wave to pulsed operation is presented. Numerical simulations based on a delay-differential-equation (DDE) model of mode-locked semiconductor lasers are used to reproduce the pulse dynamics and identify different laser operation regimes. From this, the measured single pulse operation is attributed to FM-type mode-locking. The pulse formation is explained by strong amplitude-phase coupling and spectral filtering inside the EP-VECSEL.

“…Due to TOD from the GTI-like micro-cavity pulses can have a series of decaying satellites on the leading edge that was found to cause an instability of the pulse train [22]. Without linewidth enhancement factors α 1 = α 2 = 0 the satellites are most clearly developed because of the absence of chirp and their instability can be better understood starting from this situation.…”

“…In "bad conditions" the pulse and its sattelites are smeared out into a globally broader pulse that is stable. Note that in the VCSEL-SESAM setup studied in [22] the detuning between the two micro-cavities is an additional factor leading to further complexity since second order dispersion also plays a role. Finally, we show in Fig.…”

We analyze the dynamics of passively mode-locked integrated external-cavity surface-emitting Lasers (MIXSELs) using a first-principle dynamical model based upon delay algebraic equations. We show that the third order dispersion stemming from the lasing micro-cavity induces a train of decaying satellites on the leading edge of the pulse. Due to the nonlinear interaction with carriers, these satellites may get amplified thereby destabilizing the mode-locked states. In the long cavity regime, the localized structures that exist below the lasing threshold are found to be deeply affected by this instability. As it originates from a global bifurcation of the saddle-node infinite period type, we explain why the pulses exhibit behaviors characteristic of excitable systems. Using the multiple time-scale and the functional mapping methods, we derive rigorously a master equation for MIXSELs in which third order dispersion is an essential ingredient. We compare the bifurcation diagram of both models and assess their good agreement. arXiv:2001.03446v1 [physics.optics]
