Vector soliton fission by reflection at nonlinear interfaces

Abstract

We address the reflection of vector solitons, comprising several components that exhibit multiple field oscillations, at the interface between two nonlinear media. We reveal that reflection causes fission of the input signal into sets of solitons propagating at different angles. We find that the maximum number of solitons that arises upon the fission is given by the number of field oscillations in the highest-order input vector soliton.
