| Abstract: |
| Solid-core photonic crystal fibers (PCF) can greatly enhance optoacoustic effects due to the tight confinement of both optical and acoustic modes. By leveraging the enhanced optoacoustic nonlinearity in a PCF in a mode-locked fiber laser, we have achieved the self-organization of a large number of laser solitons through long-range optoacoustic interactions mediated by coherently stimulated acoustic resonance, resulting in a highly ordered soliton sequence with prominent self-stability and flexibility. We investigated the self-organization dynamics of multi-soliton structures through a hierarchical study and simulated the process using a highly effective low-dimensional model based on coarsely grained dynamics. In addition to enabling a self-stabilizing, pattern-editable pulsed laser with a GHz repetition rate, this unique long-range interaction has also facilitated the generation of a new type of complex multi-scale soliton sequences, known as soliton supramolecules, through cooperative balancing with other interaction mechanisms. We have also realized a ``parallel optical-soliton reactor'' via controllable soliton interactions within a massive number of parallel temporal trapping potentials based on the optoacoustic effects, enabling statistical studies of laser soliton interactions. |
