Аннотация: The spin Hall effect of light, associated withspin-orbit interactions, describes a transport phenomenonwith optical spin-dependent splitting, leading to aplethora of applications such as sensing, imaging, andspin-controlled nanophotonics. Although geometricmeatsurfaces can mimic photonic spin Hall effect byspatially splitting left-hand circularly polarized and righthandcircularly polarized states of electromagnetic waveswith anomalous refraction or reflection angles, the geometricphase generated by metasurfaces hinders metalensesto realize simultaneous focusing of different spinstates, limiting further applications. Here, we proposeand experimentally demonstrate an approach to realizinga spin Hall metalens that can focus terahertz waves withdifferent spin states and flexibly manipulate spindependentfocal points in multiple spatial dimensionsbased on a pure geometric phase. A dielectricmetasurfaceconsisting of micropillars with identical shape anddifferent in-plane orientations is designed to realize themultidimensional manipulation of photonics spin Halleffect in terahertz region. Furthermore, helicity-dependentimaging is demonstrated by the terahertz spin Hallmetalens. The uniqueness and robust approach formanipulating spin photonsmay have a significant impacton designing ultra-compact and multifunctional devicesand spin photonics devices.
