## Description

- description: 'Optical chirality has been extensively explored in chiral molecules,
    helical structures, and metasurfaces with bound states in the continuum. Attempts
    to attain chirality have mainly relied on human intuition and ideas. Here, we
    show various types of single-layer silicon-nanostructured metasurfaces exhibiting
    prominent circular dichroism (CD) containing perfect, broadband, and opposite
    CD responses at short near-infrared wavelengths. The designs were obtained based
    on a generative-AI-assisted structural search for chiral metasurfaces, enabling
    a series of non-empirical structural searches beyond the boundary of human knowledge
    and experience. The physical mechanisms yielding the outstanding CD responses
    are elucidated from detailed insights into subwavelength electromagnetic dynamics
    in the single-layer metasurfaces. Furthermore, we experimentally demonstrate several
    metasurfaces. This type of single-layer thin CD metasurfaces serves as a key element
    in the development of compact optical-wave-manipulating devices at telecommunication
    bands. '
