(color online) Optical shock wave forms and evolves towards a stable dark soliton. (a) Profiles of the initial CW field (black) with white Gaussian noise and the formed optical shock wave (red). An analytical fitting of the oscillatory wave front based on Eq. (4b) is also shown as the blue circles. (b) The corresponding comb spectra. (c) Field evolution pattern. The parameters adopted in the process of calculation are: α = 2.5, β = 0.0125, F = 1.61, ρ = 1.2.
