Abstract
First-order multiple-scale perturbation theory is used to derive a set of coupled-mode equations valid for electromagnetic-wave propagation in a weakly periodic, nonlinear medium with periodicity on the order o f a wavelength. We apply this to a problem where the medium has a chi( (2)) response and find that the second-harmonic signal generated is en hanced when the fundamental is tuned near the band edge. Results are g iven for a possible experiment with optical fibers.
