An electrically controllable liquid crystal (LC) microlens with polymer crater, which is simply prepared by droplet evaporation, has been previously proposed as a focusing device possessing excellent characteristics in optical performance, especially for the capability of tunable focal lengths. As the alignment layer on the crater surface cannot be effectively rubbed, non-uniformly symmetrical electric fields in the LC lenses usually induce disclination lines during operation. In this paper, a polymer surface stabilization technique is applied to successfully prevent disclination lines and greatly improve the performance of the LC microlens with the polymer crater.
