Abstract

Metasurfaces comprising 3D chiral structures have shown great potential in chiroptical applications such as chiral optical components and sensing. So far, the main challenges lie in the nanofabrication and the limited operational bandwidth. Here, we present an effective nanofabrication method to create a 3D chiral metasurface with far- and nearfield broadband chiroptical properties. A focused ion beam is used to cut and stretch nanowires into 3D Archimedean spirals from stacked films. The spiral exhibits far- and near-field broadband chiroptical responses from 2 to 8 μm. With circularly polarized light (CPL), the spiral shows superior far-field transmission dissymmetry and handedness-dependent near-field localization. The reported method and chiral metasurface may find applications in broadband chiral optics and chiral sensing.
