Fig. 4: Instability diagrams for the homogeneous solution.
From: Modeling of dual frequency combs and bistable solitons in third-harmonic generation
Maximum modulational instability (MI) growth rates for the multistable homogeneous solution in Fig. 3 as a function of third-harmonic dispersion η2 and perturbation frequency Ω (a, b), and walk-off d (c, d). a–d show MI growth rates for the low frequency stable upper and middle branches, respectively, while the lowest branch is unconditionally stable (not shown). Case of detuning Δ1 = 6 and anomalous dispersion for the fundamental field, η1 = − 1.
