“…The resistance of the HR layer usually changes over time, which results in the properties of the LC lens becoming unstable. Some other structures, including the use of transmission lines [31][32][33][34][35][36][37], surf relief electrodes [38,39] and lens-shaped dielectric material [40][41][42], have been reported. It is difficult to obtain LC lenses with a parabolic phase profile using these techniques.…”

An electrode pattern design generating a parabolic voltage distribution, in combination with usage of the linear response range of the liquid crystal (LC) material, has been recently proposed to obtain nearly ideal phase profiles for LC lenses. This technique features low driving voltages, simple structure, compact design, and the absence of high-resistivity (HR) layers. In this work, the universal design principle is discussed in detail, which is applicable not only to LC lens design, but also to other LC devices with any phase profile. Several electrode patterns are presented to form a parabolic voltage distribution. An equivalent electric circuit of the LC lens based on the design principle is developed, and the simulation results are given. In the experiments, an LC lens using the feasible parameters is prepared, and its high-quality performance is demonstrated.

This article presents the design, fabrication, characterization, and performance evaluation of a varifocal liquid crystal (LC) lens with an inhomogeneous cell gap. The prototype employs a LC compound with high birefringence and features an optimized multilayered glass-electrode-LC configuration with a device's thickness under 1 mm, demonstrating a remarkable power tunability range of −0.44 to −2.84 diopter (D) under low voltage operation. Also, we introduce a wireless powering method to enhance the mobility and durability of the device. This ultrathin and smart lens design eliminates the need for mechanical actuation and complex control systems, offering significant potential for applications in the next generation solution of optical devices such as detachable lenses, smart contact lenses, and augmented reality systems.
