Abstract

Polarization-resolved spectroscopy imaging holds significant promise in various fields. However, conventional polarization-resolved spectroscopy imaging systems often reply on separate dispersion elements, polarization splitting components, and mechanical scanning or rotating structures, resulting in bulky systems with intricate designs. The pursuit of lightweight and seamlessly integrated polarization spectroscopy imaging systems presents a critical challenge. Here, we propose an integrated polarization spectroscopy detector operating in the mid-infrared range based on a tunable graphene metasurface. Within the graphene metasurface, plasmonic resonances of graphene are excited by a gold nano-grating, allowing simultaneous modulation of spectral and polarization transmission characteristics for infrared light by tuning the Fermi energy of graphene. With the help of neural network based recovery algorithms, this system achieves pixel-level spectral detection (with a resolution below 200 nm), multi-color polarization Stokes vector analysis (with a monochromatic angular error of less than 0.1 rad), and concurrent polarization and spectroscopy detection. This research paves the way for the development of the next generation integrated infrared polarization resolved spectroscopy imaging systems.

用于红外偏振分辨光谱检测的可调谐石墨烯等离子元器件

偏振分辨光谱成像技术在各个领域都大有可为。然而，传统的偏振分辨光谱成像系统往往依赖于独立的色散元件、偏振分光元件以及机械扫描或旋转结构，导致系统体积庞大、设计复杂。追求轻便、无缝集成的偏振光谱成像系统是一项严峻的挑战。在此，我们提出了一种基于可调谐石墨烯元表面的中红外范围集成偏振光谱探测器。在石墨烯元表面中，石墨烯的等离子共振被金纳米格栅激发，通过调节石墨烯的费米能，可同时调制红外光的光谱和偏振传输特性。借助基于神经网络的恢复算法，该系统实现了像素级光谱检测（分辨率低于 200 nm）、多色偏振斯托克斯矢量分析（单色角度误差小于 0.1 rad）以及偏振和光谱同时检测。这项研究为开发下一代集成红外偏振分辨光谱成像系统铺平了道路。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
