    Nonlinear optical effects, as a crucial form of light-matter interaction, constitute one of the physical foundations for modern photonic technologies, including high-speed all-optical communication, information processing, and quantum computing. The efficient control of these effects directly determines improvements in optical field energy conversion efficiency. Nonlinear chirality, an emerging interdisciplinary direction in nonlinear optics, combines symmetry breaking in chiral structures with nonlinear optical field manipulation, offering new approaches for single-molecule chiral recognition, ultra-pure circularly polarized light emission, and ultra-integrated photonic device development. In recent years, advances in micro-nano photonics and related technologies have significantly facilitated the customization of subwavelength-scale nonlinear chiral responses. This review first traces the development and control mechanisms of nonlinear optical effects, emphasizing the role of various electromagnetic resonance mechanisms in modulating nonlinear chiral effects. Subsequently, it examines research progress and applications in enhancing and controlling nonlinear chiral effects through micro-nano structures, focusing on specific phenomena including second-harmonic generation, third-harmonic generation, sum-frequency generation, and difference-frequency generation. Finally, it presents future perspectives, highlighting potential intersections with multiple frontier fields such as multifunctional integrated photonic devices, artificial intelligence, and quantum optics, providing valuable references for the continued development of nonlinear chiral optics.
