Dynamics of dark solitons in the Lugiato-Lefever equation with normal dispersion

In this work we present a general analysis of the regions of existence and stability of dark solitons in the  Lugiato-Lefever model with normal dispersion.  In this regime the localized states are organized in a bifurcation structure known as collapsing snaking. After characterizing the unfolding of that structure, we determine the regions of multistability of solitons in parameter space. We show that for some sets of parameters several  dynamical  instabilities, responsible for the appearing of oscillations and temporal chaos, can occur. Finally we emphasize the importance of the previous results in the  understanding of frequency comb generation in microresonators.
