Abstract
We fmd families of solitary waves mediated by parametric mixing in quadrati c nonlinear media that are localized at point-defect impurities. Solitons l ocalized at attractive impurities are found to be dynamically stable. It is shown that localization at the impurity modifies strongly the soliton prop erties. (C) 1998 Elsevier Science B.V.
