In the paper we propose the realization of liquid crystals waveguide arrays, and introduce the concept of a periodic photonic structure with refractive index changes controlled by an electric field. Such a voltage-tunable geometry, in conjunction with a reorientational nonlinearity, offers a wealth of possibilities for the study of discrete optical phenomena. Theoretical and experimental results show the presence of discrete solitons in proposed configuration.
