摘要
En 中文
We describe multiple optical functionalities obtained with a simple electrically tunable liquid crystal element that can be controlled by 4 electrodes, which are connected to a serpentine shaped transparent indium tin oxide layer. We experimentally demonstrate that the device is capable of dynamically generating refractive index distributions corresponding to a standard spherical lens, axicon, cylindrical lens, and prism. The dynamic switching of the device between these different operation modes is done in a very simple electronic way. We think that this element has a significant potential for applications in adaptive imaging, optogenetics, photonic integrated circuits, etc.(c) 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
