Abstract:
We introduce a new kind of soliton-impurity interaction by examining the
phenomena generated by colliding multiple-wave solitons in quadratic
nonlinear media with localized perturbations. We examine different models for
the impurities and find regimes of soliton self-bouncing, tunneling, and
trapping, depending on the impurity type.
Optical soliton-bouncing has never been observed experimentally (e.g. in Kerr
nonlinear media), since there have been found no suitable materials. The
soliton-bouncing that we predict requires currently available laboratory
ingredients and it should be visible in properly tailored quasi-phase-matched
samples.
