From: Multi-frequency radiation of dissipative solitons in optical fiber cavities
Panel (a) shows the spectrum at low k for the oscillating (black solid line) and non-oscillating solitons (blue dashed line). The spectrum in the vicinity of the Cherenkov resonance is shown in panel (b). Graphical solutions of the resonance condition, Eq. (6), are shown in panels (c,d), the green dashed line corresponds to the Cherenkov resonance and the red ones to the resonances with l ≠ 0. Resonances marked as 1+, 1− on panel (a) and by 1 on panel (b) are given by different crossings of the same red line with the dispersion characteristic of the linear excitations on the soliton background; the same is for the resonances marked by 2. The third order dispersion is d3 = 0.02, the pump is P = 8.
