Abstract
Terahertz flat optics based on metasurfaces can replace massive optical components with optically thin components. However, metasurfaces with unprecedented material properties frequently produce a specified function, and terahertz flat optics has yet to be commonly adopted in terahertz devices that require multiple functions. Here, we present a two-layer component composed of a collimating metalens and a quarter-wave plate that convert linearly polarized terahertz wide-angle radiation waves from a resonant tunneling diode to circularly polarized plane waves. Our findings would be applied to laminate structures with optical vortices, ultrahigh directivity and arbitrary wavefront control in 6 G wireless communications.
