title: Forward mode coupling in periodic nonlinear-optical fibers: modal dispersion cancellation and resonance solitons.
abstract: In the presence of an intensity-dependent frequency chirp, periodic linear mode coupling between two copropagating waves may counteract their temporal walkoff and lead to a new type of optical soliton that propagates at any wavelength.
