Stable single-pulse solution with the largest possible amplitude of the full governing system (black dash-dot curve), CQGLE (red dashed curve), and SGLE (green solid curve) at 𝛼₃=0.2𝜋 (a) and 𝛼₃=0.25𝜋 (b). The rest of the parameters are 𝐷=0.4, 𝜏=0.1, 𝑒₀=1, Γ=0.1, 𝛼₁=0, 𝛼₂=0.49𝜋, 𝛼_𝑝=0.45𝜋, and 𝐾=0.1. The initial conditions are 𝜓(0,𝑡)=0.5sech𝑡 (from [29], 2011, IEEE).
