摘　　要：随着高分辨率成像、信息通信、量子计算等先进技术对光电探测精度和效率的需求日益增长,偏振光探测作为光电技术的一个重要分支,正面临着前所未有的挑战和机遇。本文全面综述了基于范德华二维材料的偏振光电探测技术的最新进展,尤其聚焦于通过表面等离激元、铁电场调控以及转角材料等三种先进策略来显著提高偏振探测性能的创新方法。表面等离激元技术通过局域和传播等离激元共振增强光与材料的相互作用,显著提升了偏振探测的灵敏度和选择性。铁电场调控利用铁电材料的自发极化和局域电场,有效调节探测器件的载流子浓度和光电性能,为实现高效率和低能耗偏振探测提供了新的途径。转角材料通过调整双层二维材料之间的相对角度,引入电子结构和光学性质的可调控性,开辟了偏振探测新领域。最后展望了这些策略在未来偏振光电探测技术发展中的应用前景,强调了材料科学和微纳加工技术的综合应用将为实现高性能偏振探测器件提供强大的支持。With the growing demand for precision and efficiency in photodetection from advanced technologies such as high-resolution imaging,information communication,and quantum computing,polarization detection,as a crucial branch of photonic technology,is facing unprecedented challenges and opportunities.In response,this document provides a comprehensive review of the latest advancements in polarization photodetection technologies that harness the unique properties of two-dimensional van der Waals materials.Particularly,it focuses on innovative methods that substantially enhance the performance of polarization detectors through three advanced strategies:surface plasmons,ferroelectric field control,and twist-angle materials.These techniques not only represent the forefront of research but also hold significant potential to revolutionize the way polarization is detected,offering deeper insights and broader applications across a spectrum of scientific fields.The review aims to bridge the current technological gaps by integrating these sophisticated materials and strategies,setting a new benchmark for the capabilities of polarization photodetection systems.Surface plasmons are emphasized as a core method to enhance light-material interactions within the realm of polarization photodetection.The strategy utilizes the phenomenon of localized and propagating plasmon resonances to amplify the interaction between light and the material surface,thus significantly boosting the sensitivity and selectivity of detectors.By intricately engineering nano-scale metallic structures,such as nano-wires or gratings,it is possible to localize these plasmons,which in turn magnify the electromagnetic fields at the material′s surface.This intensification allows for the more effective detection of subtle polarization changes in light,enhancing the detector′s ability to discern complex light patterns with greater accuracy and reliability.This review further discusses the innovative approach of ferroelectric field control,which harnesses the spont
