We review linear and nonlinear light propagation in a voltage-tunable liquid crystalline waveguide array. We report on discrete diffraction, discrete soliton generation, all-optical beam steering, multiband vector breathers and Bloch oscillations. The predictions, based on full numerical BPM simulations, are in excellent agreement with the experimental results.
