摘要

偏振检测领域是当前的重要领域,如何在保证高集成度的同时确保无损检测偏振光是一个难题。目前的研究共识是建立仿生多层结构来解决这些问题,但目前的仿生多层研究仍存在无法实现图形检测、不够稳定等问题。本文在现有偏振探测结构研究的基础上,提出了一种新颖的多层铝栅元表面仿生层/石墨烯叠层偏振探测器(MAGD)来解决这一问题。受昆虫复眼的启发,MAGD 采用了三层偏振传感结构。这种结构将石墨烯和铝网格结合起来,形成仿生物结构,从而实现在单个空间点同时测量入射光的多角度分量。石墨烯与量子点的结合提高了光电效率,铝网格元表面仿生层经过优化实现了多层偏振灵敏度,从而模仿了昆虫的复眼结构。此外,通过结合多点检测,MAGD 还可用于图形检测。这种设计为未来实现更先进的偏振探测能力提供了一条前景广阔的途径,与现有系统相比,其性能有可能得到显著提高。

Multilayer Al grid metasurface bionic layer /graphene stack structure for high-performance polarization detection

The field of polarization detection is currently important, ensuring lossless detection of polarized light while maintaining a high level of integration presents a challenge. The current research consensus is to establish bionic multilayer structure to solve these problems, but current bionic multilayer research still has the problems of not realizing graphical detection and not stable enough. Building upon existing research in polarization detection structures, this paper proposes a novel Multilayer Al grid Metasurface Bionic Layer /Graphene Stack Polarization Detector (MAGD) to solve the problem. Inspired by the compound eye of insects, the MAGD utilizes a three-layered polarimetric sensing structure. This structure combines graphene and Al grid to form biomimetic structure to achieve simultaneous measurement of the multi-angular components of incident light at a single spatial point. Graphene is combined with quantum dots to improve photoelectric efficiency, and Al grid metasurface bionic layer are optimized to achieve multi-layer polarization sensitivity to mimic the insect compound eye structure. Furthermore, by combining the detection from multiple points, the MAGD can be used for graphical detection. This design offers a promising avenue for achieving more advanced polarization detection capabilities in the future and holds the potential for significantly improved performance compared to existing systems.

期刊介绍: Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
