Abstract

Originally studied in oceanography, extreme waves have attracted in recent years a great deal of attention in nonlinear optics, in particular in the context of optical fiber propagation [1–2]. In fact the first clear-cut observation of a prototype extreme wave “that appears from nowhere and disappears without a trace”, the Peregrine soliton, was reported in a fiber optics experiment of 2010 [3]. The next frontier of rogue wave research is the study of multi-component wave systems, e.g., parametric three-wave interactions in quadratic media [4].
