Soliton Molecules in an Amplified Dispersion-Managed Fiber — Jan Froh, •Alexander Hause, and Fedor Mitschke — Universität Rostock, Institut für Physik, Universitätsplatz 3, 18051 Rostock

During the last couple of years it has been demonstrated that in dispersion-managed fibers bound states of several individual solitons, so-called soliton molecules, exist. They allow to code and transmit more than a single bit of information into one clock period. This is most welcome at a time when the demand of information-carrying capacity outgrows the supply. However, all previous experiments on soliton molecules were performed using passive fibers; attenuation due to fiber and splice loss had to be accepted – not a trivial issue in a nonlinear system. We have now integrated an optical amplifier into a dispersion-managed fiber in such a way that the dispersion allocation is only minimally perturbed while sufficient gain is provided to compensate for attenuation. First results on propagation of solitons and soliton molecules will be presented.
