Fig. 3: Perturbed propagations of 1D soliton families.
From: One- and two-dimensional solitons under the action of the inverted cubic-quintic nonlinearity
The top row displays the stable perturbed propagation of 1D solitons with b = −0.9: a the fundamental soliton (which corresponds to point A1 in Fig. 1c); b the dipole soliton (corresponding to point B1 in Fig. 1d); c the tripole soliton; d the quadrupole one. The middle row displays the unstable propagation of the solitons with b = −1.55: e the fundamental soliton (corresponding to point A2 in Fig. 1c); f the dipole soliton (corresponding to point B2 in Fig. 1d); g the tripole soliton; h the quadrupole one. The bottom row displays the unstable propagation of the solitons with b = −0.02: i the fundamental soliton (corresponding to point A3 in Fig. 1c; j the dipole soliton (corresponding to point B3 in Fig. 1d); k the tripole soliton; l the quadrupole one.
