摘要

通过利用光的多个维度来实现数学函数,结构光学材料在光学信息学范式中引入了一个转折,从“用光显示”转变为“用光计算”。数学运算符的一个重要子集是二进制运算符,其输出依赖于两个输入,例如布尔逻辑。在此,我们提出并演示了一种基于热可控手性纳米结构的光学二元算子。通过设计各向异性和手性材料,输出由两个输入之间的相互作用决定;此外,伴随的Pancharatnam-Berry阶段解锁了额外的计算功能。轨道角动量和光的强度分布的定制调制使整数和图像的二进制操作成为可能。可调的工作光谱跨越超过1600纳米的超宽范围,从可见到近红外区域。这项研究揭示了软物质的新机遇,并可能促进机器视觉和光学人工智能的多种应用。

Optical Binary Operator Based on Thermally Controllable Chiral Superstructures

By harnessing multiple dimensions of light to implement mathematical functions, structured optical materials introduce a twist in the paradigm of optical informatics, shifting from “displaying with light” to “computing with light”. One vital subset of mathematical operators is binary operators, whose output depends on two inputs, such as Boolean logic. Herein, we propose and demonstrate an optical binary operator based on thermally controllable chiral nanostructures. By engineering the anisotropic and chiral materials, the output is determined by the interplay between two inputs; furthermore, the accompanying Pancharatnam–Berry phase unlocks additional computing functionalities. The customized modulation of the orbital angular momentum and intensity distribution of light enables binary operations on integers and images. The tunable operating spectrum spans an ultrawide range over 1600 nm from the visible to the near-infrared region. This study reveals new opportunities for soft matter and may facilitate diverse applications in machine vision and optical artificial intelligence.
