论文摘要
超级构成多个平面波可以产生螺旋晶格，其中光螺旋性在空间中定期变化。在这里，我们提出了一种基于将电介质包含物的数字对象放置在三维空间中的数字对象的构建任意螺旋结构的反设计方法。我们将方法应用于设计结构，该结构仅使用单个平面波作为输入来重现三维区域中的二维晶格。为了证明我们方法的功率和灵活性，我们超越了常规晶格的范式，并提出了可以创建由不同螺旋性区域组成的任意图像的结构，再次仅将单个平面波作为输入。
Superposing multiple plane waves can generate helicity lattices in which the optical helicity varies regularly in space. Here we propose an inverse design method for constructing arbitrary helicity structures based on placing a digital object of dielectric inclusions in three-dimensional space. We apply the method to design structures that reproduce two-dimensional lattices embedded within a three-dimensional region using only a single plane wave as an input. In order to demonstrate the power and flexibility of our method, we go beyond the paradigm of a regular lattice and propose structures that can create arbitrary images consisting of regions of varying helicity, again using only a single plane wave as an input.
