Soliton ensembles in a nonlinear resonator

Structure formation in a fibre resonator synchronously driven by short light pulses is considered. Light pulses develop a rich substructure which, for the case of anomalous fibre dispersion, can take the form of an ensemble of bright solitons which may exist in an irregular state (soliton gas) or as a regular array. If the fibre dispersion is normal, an ensemble of dark solitons in an irregular state can exist, but it cannot take the form of an ordered array. Cavity-dressed modulational instability at normal fibre dispersion is observed.
