  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.
