Abstract

In plasmonic systems, the enhanced photonic spin Hall effect (PSHE) was previously possible only for horizontal polarization. By employing the wave-guiding surface plasmon resonance (WG-SPR) effect, we report a giant photonic spin Hall effect (G-PSHE) of reflected light for both horizontal and vertical polarization waves. We investigated the polarization-manipulated G-PSHE in the Kretschmann configuration with an additional glass dielectric layer. This additional dielectric layer allowed us to achieve millimeter-scale (more than 2 mm to sub-millimeter) G-PSHE. We achieved polarization manipulation by designing novel structures employing wave-guiding and SPR theory. Using a simulation study, we investigated the impact of an additional thin dielectric layer on G-PSHE. This study enables the potential application of both horizontal and vertical polarization-based quantum devices and sensors for which light spin plays a pivotal role.
