We report on liquid-crystal (LC) beam steering device with a photopolymer prism produced by ultraviolet exposure. The method for producing the prism is based on the diffusion process of the prepolymer during photopolymerization. No chemical etching is needed. Our LC device gives complete single-order diffraction and a controllable steering over ∼1° with an applied ac voltage of 5 V. The experimental data, together with the simulation results with respect to electrical steering properties, are presented.
