摘要

赫米特-高斯模式（HGM）因其有趣的特性和广泛的应用而受到极大关注。在这封信中，我们提出了在一般导电片上布儒斯特角（BA）附近的 p 或 s 极化条件下高阶 HGM 的增强光子自旋霍尔效应（PSHE）的综合理论。这种布儒斯特角是由这种薄片上的表面电流引起的破坏性干扰产生的。通过改变 HGM 的阶数和薄片的电导率，可以定制 PSHE 的横向偏移。此外，我们还设计了一种具有可调灵敏度的 PSHE 柔性极化传感器。它可以检测薄片电导率的实部或虚部，灵敏度超过 105λ/S。这项工作为 PSHE 在高阶 HGM 中的应用提供了有益的启示和前景。

Enhanced photonic spin Hall effect of the high order Hermite-Gauss mode on a generic conducting sheet.

The Hermite-Gauss mode (HGM) has received great attention due to its interesting properties and extensive applications. In this Letter, we propose a comprehensive theory of the enhanced photonic spin Hall effect (PSHE) for high order HGM under p- or s-polarization near Brewster's angle (BA) on a generic conducting sheet. This BA rises from the destructive interference induced by the surface current on such sheet. The transverse PSHE shift can be tailored by altering the order of HGM and sheet conductivity. Besides, we design a PSHE enabled flexible polarization sensor with tunable sensitivity. It can detect the real or imaginary part of the sheet conductivity with a sensitivity of over 10⁵λ/S. This work provides useful insight and promising application of the PSHE for high order HGM.
