Temporal evolution of bright-bright vector solitons profiles obtained from numerical simulations using Eqs. (8) and (9) with initial condition from Eq. (13) to which small random noise is added. The profiles in (a) and (b) (resp. (c) and (d)) for \(\bar{\Psi }_1\) and \(\bar{\Psi }_2\) are obtained for \(k_1 =1.5\) and \(k_2 =1\) (resp. \(k_1 =1.673\) and \(k_2 =1.95\)). The parameters of the vector soliton in (a) and (b) (resp. in (c) and (d)) are \(A_1 =0.1\), \(A_2 \simeq 0.129\), \(b \simeq 0.759\) (resp. \(A_1 =0.1\), \(A_2 \simeq 0.964\), \(b \simeq 2.13\)).
