论文摘要
在等离子体系统中，以前仅用于水平极化，增强的光子自旋效应（PSHE）才有可能。通过采用波浪式的表面等离子体共振（WG-SPR）效应，我们报告了水平和垂直极化波的反射光的巨型光子自旋效应（G-PSHE）。我们研究了Kretschmann配置中的极化操纵的G-PSHE，并具有附加的玻璃介电层。这个额外的介电层使我们能够实现G-PSHE的毫米级（超过2毫米至亚毫米）。我们通过设计新的结构，采用波浪引导和SPR理论来实现极化操纵。使用仿真研究，我们研究了附加薄介电层对G-PSHE的影响。这项研究使基于水平和垂直极化的量子设备和传感器具有潜在的应用，而光旋转起着关键作用。
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.
