Resumo
We studied the reflective properties of an active periodic medium with quadratic nonlinearity using numerical modeling based on the description of the generation of the second optical harmonic in the quasi-optical approximation. The model under consideration appears to be a system of four coupled equations for slowly varying amplitudes of forward and backward waves. 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.
