Abstract. The simple design of liquid-crystal lenses with single electrode and operation voltage below 5 V is highly desired. We offer a new type of photoaligned liquid-crystal lens, where the refractive gradient is created by voltage application due to the patterned twist angle gradient. In this paper, we present our calculations and experimental data.

Keywords: liquid-crystal lens, twist angle gradient, photoalignment.
