Title: Multistability and coexisting soliton combs in ring resonators: the Lugiato-Lefever approach,
Abstract: We are reporting that the Lugiato-Lefever equation describing the frequency
comb generation in ring resonators with the localized pump and loss terms also
describes the simultaneous nonlinear resonances leading to the multistability
of nonlinear modes and coexisting solitons that are associated with the
spectrally distinct frequency combs.
