The self-formation of incoherent laser pulses appears paradoxical, involving both a strong instability and a temporal localization process. Incoherent pulse regimes are nevertheless recurrent within ultrafast fiber laser dynamics. In this paper, we b

The Eckhaus instability is a secondary instability of nonlinear spatiotemporal patterns in which high-wave-number periodic solutions become unstable against small-wave-number perturbations. Here we show that this instability can take place in Kerr co

We demonstrate that the Dynamic Mode Decomposition technique can effectively reduce the amount of noise in Dispersive Fourier Transform dataset; and allow for finer quantitative analysis of the experimental data. We therefore were able to demonstrate

We report experimental observation of subharmonic mode excitation in primary Kerr optical frequency combs generated using crystalline whispering-gallery mode resonators. We show that the subcombs can be controlled and span a single or multiple free s

Using the SINDy framework, we construct a Langevin’s model to describe accurately the vibration of a soliton-molecule. This simpler model allows discussions regarding the dynamics of fluctuation and dissipation mechanisms at play inside a soliton-m

There is an increased research effort on the development of smart ultrafast laser systems with the intended goal of converting the high parameter sensitivity of the complex laser dynamics from a practical challenge to an opportunity. Evolutionary alg

Most commercially available mode-locked lasers provide a single on-off pulse regime to the end user, whereas it would be advantageous to augment the pulse tuning possibilities in many applications, from micromachining to wavelength conversion. One wa

Nonlinear optics has been a productive field of research and investigation for a few decades now, but the rapid progression of photonic integration platforms in recent years has opened up a whole new range of applications. On-chip integration of effe
We implement a super-localization method in the time domain that allows the observation of the external motion of soliton molecules in a fiber ring cavity laser with unprecedented accuracy. In particular, we demonstrate the synchronization of two osc

We investigate the effects of environmental stochastic fluctuations on Kerr optical frequency combs. This spatially extended dynamical system can be accurately studied using the Lugiato-Lefever equation, and we show that when additive noise is accoun
