It is always expected that the conversion efficiency is as high as possible for nonlinear interactions at any pump intensity. We present a method of controlling the conversion efficiency of sum-frequency generation in the periodic optical superlattices with different duty cycles, which is based on the controllable linear gratings induced by electro-optic effect here. The calculated results verify that this method is feasible and very efficient in attaining the complete transfer between the pump and sum-frequency waves at any given pump intensity. In addition, we demonstrate the electric-optic control is better than temperature control.
