摘要：

Using a Bloch function approach, we predict the existence of parametric gap solitary waves in a grating structure with quadratic nonlinearity. These waves consist of mutually trapped envelopes at the fundamental frequency and at the second harmonic, which are not sustained by any equivalent cubic nonlinearity.
