It was shown in many experiments that chromatic dispersion plays a leading role in the dynamics of semiconductor lasers [1]. Beyond second order dispersion (SOD), third order dispersion (TOD) is the lowest order non-trivial parity symmetry breaking effect, which leads to convective instabilities [2] and drifts. In this work [3] we show that SOD and TOD appear naturally in the modeling of Vertical External-Cavity Surface-Emitting Lasers (VECSELs), Mode-Locked Integrated External-Cavity Surface Emitting Laser (MIXSELs), and nonlinear resonators with intracavity Gires-Tournois etalons [4].
We investigate how TOD destabilizes mode-locked pulses and generate an innite sequence of decaying satellites accumulate in front of the pulse leading edge. Experimental evidences are provided showing good agreement with model predictions [3].
More details will be presented at the NUSOD-20 conference.
