Figure 4. Surface plot of the solitary wave versus dimensionless time t/2LD and position z/z0 for collision between two solitons under four different choices of amplitude ratio and relative phase, i.e. (a) q = 1, φ = 0; (b) q = 1, φ = π/4; (c) q = 1, φ = π/2, and (d) q = 1.1, φ = 0. Initially the separation of the solitons is 70 units length, corresponding to ξ(0) = 3.5. The time is 20 times the dispersion length, corresponding to 20LD. The system parameters are chosen as κ/2π = 3.8 MHz, J/2π = −95 GHz, ωc = 2.3 eV, g0 = −2.9 meV, G = 0, N = 100, Γ = 2.65 meV.
