Applying a bifurcation analysis and numerical relaxation technique, we reveal different scenarios of creating the multi-hump solitons and find the families of solitary waves composed of two mutually coupled components. We analyse the stability of these solitons to propagation and find that the evolution of a soliton is governed by its modal structure.Keywords: Multi-hump optical solitons; Multi-soliton structures; Solitons in photorefractive media19992015-12-12
