Propagation of light in an optically induced waveguide array in biased photorefractive media with a quadratic electro-optic effect is investigated numerically with the beam propagation method. The refractive index distribution of the array is induced by two coherent plane waves interfering in a guiding layer in a photorefractive multiple quantum well (MQW) planar waveguide. The influence of modulation depth and the space period of an interference pattern as well as the external electric field intensity on diffraction properties of the array is analysed. The potential possibility of all-optical switching due to the dependence of the guided wave output distribution on the external waves parameters is shown.
