“…30,31 In the past decades, some chiral and anisotropic plasmonic metasurfaces have been widely used by integrating with a photodetector to realize compact on-chip polarization-sensitive photodetection. Some chiral 32,33 and anisotropy 34 plasmonic metasurfaces were used to detect CPL and LPL by integrating with semiconductors due to their polarization-sensitive detection. However, few reports can distinguish both CPL and LPL in a single device, even though it is important to achieve multiple functionalities to meet the increasing demand for miniaturization and integration in optoelectronics.…”

“…Possessing the ability to bind to light fields and displaying sensitivity to polarized light, optical low-dimensional materials can effectively differentiate between linearly and circularly polarized light, a crucial aspect for polarization detection . The polarization-dependent light response of optical low-dimensional materials can be modulated via engineering of additional structures, selecting diverse material types, and applying external local fields, − thereby facilitating the detection and manipulation of specific polarized light.…”

Enantiomeric discrimination plays a crucial role in the fields of analytical science and chemical biology. Herein, we achieve chiral recognition via angle-resolved polarized Raman scattering using a composite material consisting of an anisotropic twodimensional material, ReSe 2 , and chiral Au nanoparticles (CAuNPs). A near-field effect is induced through the attachment of CAuNPs to ReSe 2 , in conjunction with modulation of polarized light, resulting in simultaneous angular polarization of ReSe 2 . This angular polarization was utilized for the chiral detection of tyrosine. Varying enantiomeric excess (ee) leads to inverse nonreciprocal angular deflections, which we propose arise from interactions between the chiral near-field and optical vectors modified by chiral molecules with distinct ee values. This phenomenon is primarily attributed to the optical spin Hall effect within the field, generating distinct vector deflections that can be utilized to discriminate between different enantiomers. Ultimately, we demonstrate selective identification of chiral substances by establishing a correlation between the optical inversion angle and ee value. This investigation presents an efficient and insightful approach for achieving rapid detection of chiral substances using rational optical devices.

The vector characteristics of light and the vectorial transformations during its transmission lay a foundation for polarized photodetection of objects, which broadens the applications of related detectors in complex environments. With the breakthrough of low‐dimensional materials (LDMs) in optics and electronics over the past few years, the combination of these novel LDMs and traditional working modes is expected to bring new development opportunities in this field. Here, we mainly focus on the state‐of‐the‐art progress of LDMs as polarization‐sensitive components in polarized photodetection and even the imaging, with emphasis on the relationship between traditional working principle of polarized photodetectors (PPs) and photoresponse mechanisms of LDMs. Particularly, from the view of constitutive equation, the existing works are reorganized, reclassified and reviewed. The perspectives on the opportunities and challenges are also discussed. We hope that this work can provide a more general overview in the use of LDMs in this field, sorting out the way of related devices for “more than Moore” or even the “beyond Moore” research.This article is protected by copyright.
