A switchable liquid crystal (LC) Fresnel lens was demonstrated by the UV-modified alignment layer for producing an alternation of hybrid-aligned and vertically-aligned LC zones. A polarization-independent Fresnel lens can be obtained by circular rubbing, and a high diffraction efficiency of ∼23% is reached with a low driving voltage of 1.2 V.
