Discrete set of states of dispersion-managed soliton molecules — •Alexander Hause and Fedor Mitschke — Universität Rostock, Institut für Physik, Universitätsplatz 3, 18051 Rostock

Bound states of two and of three solitons in dispersion-managed fibers (soliton molecules) were experimentally demonstrated recently. These compounds potentially allow a two bit per time slot data transmission [1]. A perturbation treatment is developed to predict equilibria of the relative positions of the solitons in the molecule. We find a multitude of quantized separations, alternatingly stable and unstable. Next neighbor solitons can have the same or opposite phase. The number of possible equilibria is limited by the level of the radiation background. The state with the smallest separation and the highest binding energy (ground state) always occurs for opposite-phase pulses, the lowest-order state for in-phase pulses is always unstable. Stable chains of solitons can be built with a mixture of different next-neighbor separations and phases. Stable and unstable ground states are confirmed by experiments.
