Abstract :
Fluctuations in soliton amplitude cause significant changes in femtosecond soliton-soliton interaction as a result of the soliton self-frequency shift. It is shown that a small subpulse which is coherently added to or subtracted from a soliton pulse greatly modifies the soliton-soliton interaction in a distributed erbium-doped fibre amplifier. This effect is significantly enhanced by the optical gain.
