Abstract

The most interesting property of a soliton is the transfer of energy in a localized state, providing similarities to particle-like behavior. An extension of this analogy is given by the concept of soliton molecules [1], opening up new perspectives in fundamental science as well as applications in optical technologies. The standard nonlinear Schrödinger equation does not contain a direct solution for a molecule soliton state, so that one needs additional prerequisite, such as the use of a dispersion-managed fiber allowing stable propagation of double-humped intensity profiles consisting of two solitons [1]. Here we propose a completely different approach for the creation of molecule-like states distinct from the usual soliton molecules. These new states represent highly robust, radiating two-color soliton compounds with a binding energy, providing a plethora of diverse propagation dynamics and further analogies to the quantum mechanical-like behavior of molecules as the evaporation of energy upon impact. Figure 1(a) shows a stable compound state generated by the collision of two solitons, sharing features of quantum mechanical reaction kinetics supporting the formation of molecules. A major precondition is the co-propagation of two solitons with similar group velocity, but different frequencies, similar to the conditions for a repulsive interaction between a soliton and a dispersive wave [2,3].
