Desynchronization of temporal solitons in Kerr cavities with pulsed injection

Abstract

A numerical and analytical study was conducted to investigate the bifurcation mechanisms that cause desynchronization between the soliton repetition frequency and the frequency of external pulsed injection in a Kerr cavity described by the Lugiato–Lefever equation (LLE). The results suggest that desynchronization typically occurs through an Andronov–Hopf (AH) bifurcation. Additionally, a simple and intuitive criterion for this bifurcation to occur is proposed.
