Abstract

We investigate electromagnetic localization in a nonlinear photonic crystal, i.e., a structure with a stop band in its nonlinear spectral response. Taking a one-dimensional model of degenerate two-wave interaction we introduce the concept of parametric nonlinear-gap solitons, that is, strongly localized two-color locked envelopes arising from interplay of two nonlinear effects, which propagate slowly. We discuss the observable signature of these novel localized structures.
