Multimode resonance transition to collapsed snaking in normal dispersive Kerr cavities: bright versus dark solitons

We study the dynamics of Kerr cavity solitons in the normal dispersion regime in the presence of an intracavity phase modulation. The associated parabolic potential introduces multimode resonances, which promote the formation of high-order bright solitons. By gradually reducing the potential strength, bright solitons undergo a transition into dark solitons. We describe this process as a shift from a multimode resonance to a collapsed snaking bifurcation structure. This work offers a comprehensive overview of cavity dynamics and may provide a potential pathway to access multi-stable states by effectively varying the phase modulation.(c) 2023 Optica Publishing Group

Automated summary

This study investigates the dynamics of Kerr cavity solitons with intracavity phase modulation in the normal dispersion regime. The introduction of a parabolic potential leads to multimode resonances, which facilitate the formation of high-order bright solitons. Gradually decreasing the potential strength causes the bright solitons to transition into dark solitons. This process is described as a shift from multimode resonance to collapsed snaking bifurcation structure. This work provides a comprehensive overview of cavity dynamics and offers a potential pathway to access multi-stable states by varying the phase modulation effectively.
