Transition dynamics observed in the anomalous dispersion regime. (a) and (b) Simulations of the full governing equations at 𝑔₀=1.9 ((a) and (c)) and the corresponding pulse profile ((b) and (d)). (c) and (d) Simulations of the SGLE at 𝑔₀=2.25 ((a) and (c)) and the corresponding pulse profile ((b) and (d)). The rest of the parameters in the simulations are 𝐷=0.4, 𝛼₁=0, 𝛼₂=0.82𝜋, 𝛼₃=0.1𝜋, 𝛼_𝑝=0.45𝜋, 𝐾=0.1, Γ=0.1, 𝑒₀=1, and 𝜏=0.1. The initial conditions in all the simulations are 𝜓(0,𝑡)=sech0.5𝑡(from [29], 2011, IEEE).
