摘要

在快速发展的太赫兹领域,具有动态功能的集成平面光学器件需求量很大。特别是变焦消色差超透镜在生物化学鉴别成像和无损检测中具有重要的应用价值。本文提出了一种实现变焦消色差超构透镜的设计方案。它的工作原理是在适当预设传播相位群延迟的基础上,同时补偿可调焦基本相位轮廓的衍射色散。用集成硅超构透镜的液晶证明了这一概念。柱状元原子的长轴取向提供了一个固定的几何相位,光模式液晶提供了一个可切换的几何相位,补偿源于柱状元原子的形状变化。仿真和实验验证了在1.0-1.6太赫兹的两个不同焦点(10.20和13.76 mm)上可切换消色差聚焦。两种药物的双深度多光谱成像进一步证明了其在无损安全筛选和药物鉴定方面的潜力。提出的策略为下一代自适应太赫兹技术和应用建立了一个框架。

Liquid‐Crystal‐Enabled Varifocal Achromatic Metalens
Integrated planar optical devices with dynamic functionalities are in high demand in the rapidly developing terahertz region. In particular, varifocal achromatic metalenses are urgently needed for biochemical discrimination imaging and nondestructive inspection. Here, a design is proposed to realize a varifocal achromatic metalens. It works on the simultaneous compensation of the diffraction dispersion of a foci‐switchable basic phase profile on the basis of a properly preset group delay of a propagation phase. The concept is demonstrated with a liquid crystal integrated silicon metalens. The major axis orientation of cylindroid meta‐atoms supplies a fixed geometric phase, the photopatterned liquid crystal provides a switchable geometric phase, and the compensation originates from the shape variation of cylindroid meta‐atoms. Both simulations and experiments verify the switchable achromatic focusing at two distinct foci (10.20 and 13.76 mm) across 1.0–1.6 THz. Dual‐depth multispectral imaging is further demonstrated with two medicaments, exhibiting its potential for nondestructive safety screening and pharmaceutical identification. The proposed strategy establishes a framework for next‐generation adaptive terahertz techniques and applications.
