The influence of the Raman effect on bound states of dissipative solitons is investigated theoretically by means of numerical simulations and an analytical model. The numerical simulations show that the Raman effect modifies the group velocity of a bound state of solitons differently from that of a single soliton, in agreement with experimental results obtained with fiber lasers. The results are interpreted in terms of two distinct mechanisms acting within the bound state, the Raman-induced self and cross-frequency shifts. The implication of this effect on the phenomenon of soliton collisions in fiber lasers is discussed.
