V-soliton solution of absolute behaviour for Eq. (4.8) with the parametric values: (a) 3D plot illustrates the propagation of V-shaped profile along the x-t plane; (b) 2D profiles at \(t = 0\) (red line), \(t = -5\) (purple line) and \(t=5\) (green line); (c) Contour map depicts the combined effect of spectral broadening and phase shift dynamics.
