Chirality is a universal geometric property in both micro‐ and macroworlds. Recently, optical chiral effects have drawn increased attention due to their great potential in fundamental studies and practical applications. Significantly, the optical chiral response of artificial structures can be enhanced by orders of magnitude compared to that of their naturally occurring counterparts. These man‐made structures generally exhibit two types of optical chirality: extrinsic chirality and intrinsic chirality. The former relies on external illumination conditions, while the latter arises from the geometric characteristics of 3D objects. Herein, this review mainly focuses on the intrinsic chirality of artificial structures and discusses the existing realizations based on their design principles. In particular, an overview is given of the recent demonstrations of nonlinear optical effects in chiral structures and active chiral structures. Lastly, some promising prospects for future studies in the field are outlined.

具有固有手性的3D超光子纳米结构

在微观世界和宏观世界中，手性都是一种普遍的几何特性。近来，光学手性效应由于其在基础研究和实际应用中的巨大潜力而引起了越来越多的关注。重要的是，与天然结构相比，人工结构的光学手性响应可以提高几个数量级。这些人造结构通常表现出两种类型的光学手性：外部手性和内在手性。前者取决于外部照明条件，而后者则取决于3D对象的几何特征。本文中，本文主要关注人造结构的内在手性，并基于其设计原理讨论了现有的实现方式。尤其是，概述了手性结构和活性手性结构中非线性光学效应的最新证明。最后，概述了该领域未来研究的一些有希望的前景。
