Multimode resonance transition to collapsed snaking in normal dispersion Kerr resonators: Bright versus dark solitons

TL;DR

This paper investigates how intracavity phase modulation influences Kerr cavity solitons in normal dispersion regimes, revealing a transition from bright to dark solitons via multimode resonance and collapsed snaking bifurcations.

Contribution

It introduces a novel understanding of the transition mechanism between bright and dark solitons in Kerr resonators through phase modulation effects.

Findings

Bright solitons form due to multimode resonances.

Reducing potential strength causes bright-to-dark soliton transition.

Collapse of snaking bifurcation structure observed during transition.

Abstract

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.
