Paper Abstract

We have studied the harmonic generation and the effective nonlinear-optical coefficients of the quasi-periodic optical superlattice (QPOS). It has been shown that the effective nonlinear-optical coefficients in QPOS are the extension of that in periodic optical superlattice (POS). The intensities of the harmonic generation obtained by the coupled-wave equations are in good agreement with prediction by the effective nonlinear-optical coefficients.
