Bright stationary solitary waves in deep gratings with a quadratic nonlinearity.
We present localized, bright, stationary soliton solutions to the coupled-mode equations for quadratically nonlinear media with a deep grating. We find that the required peak intensities can be significantly lower than might be expected from a shallow grating treatment.
