We study the dynamics of bound solitons of the complex cubic-quintic Ginzburg­ Landau equation under the
influence of external modulation. We consider periods of modulation being either smaller or larger than the
soliton separation and the amplitude of modulation being either real or imaginary. For each case, we observe
bifurcation and hysteresis phenomena in the parameters of the pair when changing the amplitude of modula-
