The devil’s staircase of breathing soliton molecules
Year: 2026
Type: article
Abstract: The devil’s staircase is a particularly fascinating synchronization phenomenon widely presented in science and engineering, manifesting as an infinite number of synchronized state when tuning parameters. Optical breathing soliton oscillator has attracted significant interest in studying devil’s staircase phenomena within a single cavity. However, the devil’s staircase of multiple breathing solitons under interaction is remained unexplored. Here, we study the synchronization dynamics of breathing soliton molecules under soliton interaction, and present the first evidence of devil’s staircase in breathing soliton molecules within a mode-locked fiber laser. The devil’s staircase of breathing soliton molecule exhibits a larger winding number than a single breathing soliton, which is of great significance to densify the frequency comb. Interestingly, the devil’s staircase of breathing soliton molecules exhibits a stronger tendency toward chaotic behavior, which may indicate a new method to access a chaotic state. Supported by numerical simulations, our conclusions lay a foundation for future studies on fractal, synchronization, and chaos dynamics in the regime of interactional breathing solitons.
