Rogue waves : from Hydrodynamics to Optics

par Saliya COULIBALY - publié le

Wave propagation in nonlinear extended systems may generates a large variety of complex self-organizations. Examples include triangles, hexagons, rolls, localized structures (dissipative soliton, fronts, kinks, localized states), propagative domain walls, and many other structures. An outstanding feature of these structures is their universality which is manifested by observations any almost all the areas of nonlinear Physics. In our group we are interested on a specific type of Localized Structure : the rogue waves. Rogue waves originally designate abnormally high ocean surface waves. These devastating walls of water are short-lived and extremely rare and constitute one of the fascinating manifestations of the strength of nature : They appear from nowhere and disappear without a trace [1]. They are recognized by sailors for nearly a century, but large scale, systematic scientific studies have been undertaken only in the past twenty years, initially in the field of oceanic waves [2]. Experimental evidence of optical rogue waves in a fiber system has been established first for pulsed regime in [3], by our group in the continuous (CW) regime [4], and has received considerable attention since [5,6]. Intensive studies have since been pursued in diverse fields of physics, e.g. acoustics, capillarity and plasma, and rogue waves are even studied under the category of "extreme and rare events in physics" [7]. Hence, on this topic, we are mainly concerned with the (i) control, (ii) formation mechanisms, (iii) interaction processes of optical rogue waves.
