Query: Vector soliton fission by reflection at nonlinear interfaces   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.
