Using the quasi-particle approach, we studied the problem of the reflection of quadratic spatial solitons from an interface between two χ(2) media with slightly different linear and nonlinear properties. The possibility of soliton capture by an interface associated with nonlinear surface wave excitation is shown. The calculations are carried out for the well-known single as well as a novel type of multihump soliton, for which we obtain a new analytical expression in the nonlocal limit for the first time to our knowledge.

  8. The possibility of the capture of the solitons by the interface between two second-order nonlinear media is more or less obvious, at least in the cascading limit, since this situation corresponds to an effective cubic medium, for which nonlinear surface waves are well known (see, e.g., Ref. 4).
