摘要

Abstract

Spin photonics revolutionizes photonic technology by enabling precise manipulation of photon spin states

with spin-decoupled metasurfaces emerging as pivotal in complex optical field manipulation. Here

we propose a folded-path metasurface concept that enables independent dispersion and phase control of two opposite spin states

effectively overcoming the limitations of spin photonics in achieving broadband decoupling and higher integration levels. This advanced dispersion engineering is achieved by modifying the equivalent length of a folded path

generated by a virtual reflective surface

in contrast to previous methods that depended on effective refractive index control by altering structural geometries. Our approach unlocks previously unattainable capabilities

such as achieving achromatic focusing and achromatic spin Hall effect using the rotational degree of freedom

and generating spatiotemporal vector optical fields with only a single metasurface. This advancement substantially broadens the potential of metasurface-based spin photonics

extending its applications from the spatial domain to the spatiotemporal domain.
