Abstract

An ultrasmall tunable microlens with a diameter of 1.5 μm is fabricated using nematic liquid crystals (electrically tunable medium) and vertically aligned carbon nanofibers (CNFs, electrodes). Individual CNFs are grown at the center of circular dielectric regions. This allows the CNFs to produce a more Gaussian electric field profile and hence more uniformity in lens array switching.

摘要

采用向列相液晶（电可调谐介质）和垂直排列的碳纳米纤维（CNF，电极）制作出直径为 1.5μm 的超小可调微透镜。在圆形介电区域的中心生长单个 CNF，这使得 CNF 产生更高斯的电场分布，从而在透镜阵列切换中具有更高的均匀性。
