Sketch of physically equivalent phenomena.
(a) coupling of bound states to continuum induced by generic potential which is oscillating in time. (b) fiber with oscillating diameter (dispersion) which induces wavepackets that are localized in time thanks to a self-induced potential given by the nonlinearity to couple into the radiation continuum at characteristic resonant frequencies.
