Abstract
The reflective properties of an active periodic medium with quadratic nonlinearity are studied based on a description of the second optical harmonic generation in the quasi-optical approximation. Based on numerical simulation, the influence of the asymmetric Bragg coupling of counterpropagating waves at the fundamental frequency on the absorbing/generating and reflecting properties of the active medium is analyzed.
