(color online) Different soliton structures of A(z,x) with the appropriate parameters: (a) Single soliton structure with ε = 1, k₁ = 1, k₂ = 0.75, c₁ = 2, c_i = 1 (i = 2,3,4,5,6) and θ_i = 1 (i = 1,2). (b) Dromion structure with ε = 1, k_i = 1 (i = 1,2), c_i = 1 (i = 1,2,3,4,5,6) and θ_i = 1 (i = 1,2).
