Cylindrical and Powell liquid crystal lenses with positive-negative optical power

We demonstrate a technique to engineer cylindrical and Powell liquid crystal lenses with positive or negative optical power. The device is based on two indium-tin-oxide electrode combs and a microstructured voltage transmission electrode. The technique features the advantages of a multielectrode lens, albeit using a single lithographic step and only two voltage sources. Extensive control of the phase profile across the device active area is demonstrated, achieving both positive and negative optical power. The lens aperture is not constrained by the geometrical parameters and can be scaled to larger values.This work was supported in part by the Comunidad de Madrid and FEDER Program under Grant S2018/NMT-4326, in part by the Ministerio de Economía y Competitividad of Spain under Grant TEC2013-47342-C2-2-R and Grant TEC2016-76021-C2-2-R, in part by the FEDER/Ministerio de Ciencia, Innovación y Universidades and Agencia Estatal de Investigación under Grant RTC2017-6321-1, Grant PID2019-109072RB-C31, and Grant PID2019-107270RB-C21, in part by the Ministry of National Defense of Poland under Grant GBMON/13-995/2018/WAT, and in part by the Military University of Technology under Grant 23-895
