微尺度手性阵列光场的生成与调控特性研究

Generation and Regulation Characteristics of Microscale Chiral Array Light Field

通过在入射光引入平移位相因子,从而实现了一种基于Richards‑Wolf矢量衍射理论的微尺度手性阵列光场的生成。通过模拟研究,进一步实现了阵列尺寸、阵列子单元手性的灵活调控。此外,探究了阵列的传播特性,在±λ传播距离内手性阵列光场均保持光场模式分布。该研究极大的丰富了手性强度光场的模式,在手性微纳材料的制备等领域具有良好的应用前景。

The generation of a microscale chiral array light field based on Richards‑Wolf vector diffraction theory was realized by introducing a translational phase factor into the incident light.Through simulation research,the flexible regulation of array size and chirality of array subunits was further realized.In addition,the propagation characteristics of the array were explored,and the light field pattern distribution of the chiral array light field was maintained within the±λpropagation distance.This study greatly enriches the mode of chiral intensity light field,and has good application prospects in the preparation of chiral micro‑nano materials.
