Simple photonic fiber-based workbenches have been able to emulate well-known nonlinear wave dynamics occurring in deep or shallow water conditions. Here, by investigating the nonlinear reshaping of a flat-top pulse upon propagation in an anomalous dispersive optical fiber, we observe that typical signatures of focusing dam break flows and Peregrine-like breather events can locally coexist in spontaneous pattern formations. The experimental measurements are in good agreement with our numerical predictions.
简单的基于光子光纤的工作台已经能够很好地模拟在深海或浅海条件下发生的众所周知的非线性波动动力学。在这里，通过研究在反常色散光纤中传播时平顶脉冲的非线性整形，我们观察到聚焦溃坝流和类徘徊呼吸子事件的典型特征可以在自发模式形成中局部共存。实验测量与我们的数值预测吻合得很好。
