Abstract
The shot-to-shot stability of a supercontiuum (SC) can be controlled both in terms of coherence and intensity stability by modulating the input pulse with a weak seed [1-3]. In the long-pulse regime, the SC generation is initiated by noise-seeded modulation instability (MI), which breaks the pump into solitons and dispersive waves. To control the spectral evolution and reduce the noise, it has been proposed to provide a seed, i.e. a weak pulse with a frequency offset relative to the pump, within the MI gain spectrum in order to ensure a deterministic rather than noise-seeded pulse break-up [1,2]. Seeding the pulse break-up has likewise been used to control the generation of otherwise statistically rare large-amplitude rogue solitons [2-4]. In this work, we numerically investigate the influence of the MI gain spectrum on the pulse break-up and rogue wave generation. We find that the results can be clearly divided into a number of distinct dynamical regimes depending on the initial four-wave mixing process and demonstrate that seeding can be used to generate coherent and incoherent rogue waves.
