The fundamental peculiarities of discrete diffraction in periodically poled lithium niobate waveguide arrays by applying an electrical field through electro-optics effect are studied. The discrete diffraction properties of such arrays can be effectively altered, depending upon the input conditions. By slightly changing the input conditions, light can experience normal diffraction, anomalous diffraction and even zero diffraction. We show that these three different kinds of discrete diffraction can be modulated by applied voltage in periodically poled lithium niobate waveguide arrays.
