Optical gap solitons in nonresonant quadratic media.
We demonstrate an important role of the process of optical rectification in the theory of nonlinear wave propagation in quadratically nonlinear [or chi(2)] periodic optical media. We derive a novel physical model for gap solitons in chi(2) nonlinear Bragg gratings.
