Emission of dispersive waves from a train of dark solitons in optical fibers

International audienceWe report the experimental observation of multiple dis-persive waves emitted in the anomalous dispersion region of an optical fiber from a train of dark solitons. Each individual dispersive wave can be associated to one particular dark soliton of the train, using phase-matching arguments involving higher-order dispersion and soliton velocity. For a large number of dark solitons (> 10), we observe the formation of a continuum associated with the efficient emission of disper-sive waves
