“…Such collisions are favored by convective mechanisms such as the third-order dispersion or the Raman response of silica [62]. A dedicated care should be provided to their detection by a frequency offset filter that can in itself create an artifact [63] and may not see these collision events directly [64; 65] as the emerging temporal spike of light does not correspond to the most red-shifted event. In the process of collision, an energy exchange also occurs, leading to the progressive growth of a giant soliton, where most of the energy of the system will eventually concentrate [66; 67].…”

We provide an overview of our recent work on the shaping and stability of optical continua in the long pulse regime. Fibers with normal group-velocity dispersion at all-wavelengths are shown to allow for highly coherent continua that can be nonlinearly shaped using appropriate initial conditions. In contrast, supercontinua generated in the anomalous dispersion regime are shown to exhibit large fluctuations in the temporal and spectral domains that can be controlled using a carefully chosen seed. A particular example of this is the first experimental observation of the Peregrine soliton which constitutes a prototype of optical rogue-waves. © 2012 ElsevierKeywords: Fiber optics; supercontinuum ; pulse shaping ; extreme statistics ; optical solitons 3 IntroductionNonlinearity in single-mode optical fibers has often been regarded as a detrimental effect for the transmission of pulsed signals. However, when properly managed, nonlinearity offers great opportunity to reshape the optical spectrum of coherent light and expand its bandwidth to several hundreds of nanometers. For example, in the early 1990's, supercontinuum (SC) generated in optical fibers has found several practical applications in dense wavelength-division multiplexed The physics of the continuum generation is generally complex and crucially depends on the dispersion properties at the pump wavelength. However, chromatic dispersion is not the only parameter affecting the output spectrum, the input pulse duration, peak power and pulse shape also strongly influence the output and further increase the richness and diversity of the nonlinear 4 propagation dynamics. In this paper, we choose to focus on how these parameters influence the stability characteristics of SC spectra and how they can be controlled in different regimes. In this respect, the performance of normally dispersive fibers is seen as superior to that of anomalousdispersion fibers, where large shot-to-shot fluctuations are seen both in the temporal and spectral domains [5]. In this context, the observation of rare but intense spikes of light [6] in the anomalous-dispersion regime has initiated the field of optical rogue waves and has provided a new perspective for the analysis of SC stability. This, in turn, has highlighted or confirmed the crucial role of nonlinear coherent structures such as fundamental solitons [7; 8], breathers [9; 10] and rational solitons such as the Peregrine soliton [11].Several review articles and books are now available to understand the physical mechanisms driving the continuum formation and its modeling using the nonlinear Schrödinger equation (NLSE) in its extended form [12; 13; 14; 15; 16]. Therefore it is not our intention here to present an additional comprehensive or analytical description of the nonlinear dynamics of pulses propagating in an optical fiber, but rather to provide an overview of our recent numerical and experimental contributions to the field of SC generation in both the normal and anomalous dispersion regimes. To this end, we restrict ourselv...

“…We first implement this concept for picosecond pulses at telecommunication wavelengths where the targeted TF is generated thanks to self-phase modulation (SPM) followed by optical bandpass filtering [3]. A second implementation is proposed in order to deal with femtosecond pulses delivered around 1µm [4].…”
