However, graphene photodetectors suffer from challenges such as low responsivity and high noise. Due to its strong interaction with light and low density of states, the optoelectronic properties of graphene can be easily manipulated by local fields. Manipulation of local fields in graphene photodetectors is a promising strategy to improve detection performance and expand functionality. In this review, the manipulations of local optical fields are introduced, which include the combination of graphene with local photonic structures and the fabrication of graphene nanostructures. Then, the manipulations of local electric field, specifically through the control of the electrostatic field and the built-in electric field, are discussed. Moreover, the functional graphene optoelectronic devices are introduced, categorized into polarization-sensitive photodetectors, spectral detectors, bionic devices, and logic devices.

In situ irradiation (ISI)–electron paramagnetic resonance and ISI–X-ray photoelectron spectroscopy combined with DFT calculations reveal that the visual response behavior is attributed to the dynamic evolution of a distinct local structure containing TiO6, TiO5N, and SmO6 units connected via the bridging oxygen atom. Upon UV irradiation, the localization of the photogenerated electrons induces a rapid release of bridging oxygen atoms, creating oxygen vacancies, effectively hindering the energy transfer from TiO2 to Sm3+ and resulting in a strong luminescence modulation that reaches the theoretical maximum (99.9%) within 1 s. With prolonged UV exposure (3–20 s), the bridging oxygen vacancies act as electron traps, and the photogenerated electrons accumulate around the Ti atoms near them. This causes the film to transition from white to dark blue, achieving a high photochromic contrast (51.4%). A foundation for advanced information encryption and anticounterfeiting is established based on the different time scales of luminescence modulation and photochromism. This study confirms the application potential of the film in “burn after reading” and dynamic information encryptions and advanced anticounterfeiting labels, and it offers comprehensive insights into the design of smart photoresponsive materials.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 7","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disordered nanostructures significantly enhance light scattering and absorption, thereby broadening the spectral response range and enabling the sensitive detection of multi-dimensional physical information, including angle, wavelength, and polarization state. Here, by combining disordered nanostructures with silicon-on-insulator (SOI) waveguides, an integrated light-field sensor that integrates angle, wavelength, and polarization detection is successfully realized. The sensor, with a compact integration footprint of 32 × 32 µm2, demonstrated angle detection with a resolution of 3.2° within elevation angles ranging from −20° to 20°, and spectral reconstruction with a resolution of 3.25 nm across wavelengths from 1520 to 1550 nm. Additionally, azimuth and polarization state detection functionalities are further validated.

Recent advances have shifted from traditional electromagnetic enhancement methods to chemically enhanced Raman scattering, offering significant advantages. However, these advancements have typically depended on indirect and empirical models. This article introduces a systematic method for the rational design and engineering of chemical enhancement to Raman scattering. This method involves identifying promising Raman enhancers and optimizing their morphology and composition by elucidating their photochemical properties and mapping their charge-transfer pathways with target molecules using transient absorption spectroscopy (TAS), cyclic voltammetry (CV), and density functional theory (DFT) calculations. Employing this method, this work has developed a series of rationally designed Raman enhancers made from conducting polymers (CPs), such as poly(3,4-ethylenedioxythiophene) (PEDOT), with optimized morphological traits and compositions. These enhancers significantly improve surface-enhanced Raman spectroscopy (SERS), achieving a reproducible enhancement factor of up to 106, and boost Raman lasing, with a remarkable 40-fold increase in energy conversion efficiency.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the imaging distance of an OAM hologram is typically inflexible and determined by the focal length of the Fourier transform lens placed behind the hologram. Here, 3D orbital angular momentum holography is proposed and implemented. The Fourier transform between the holographic plane and imaging plane is performed by superimposing Fresnel zone plates (FZP) onto the computer-generated holograms (CGH). The CGH is binarized and fabricated on the lithium niobate crystal by femtosecond laser micromachining. Experimental verification demonstrates the feasibility of the encoding method. Moreover, by superimposing FZPs with different focal lengths into various OAM channels, OAM-multiplexing holograms are constructed. Target images are separately projected to different planes, thereby enabling 3D multi-plane holographic imaging with low crosstalk. The interval between adjacent imaging planes can be uniform and minimal, free from depth of field (DoF) constraints, thus achieving high longitudinal resolution. This work achieves OAM holography in a more compact manner and further expands its applicability.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, 3dPDs constructed with heterostructures still face major challenges and have yet to demonstrate self-powered polarization-sensitive photodetection, owing to the extreme difficulties in 3D assembly of heterostructures and the fabrication of perfectly-matched electrodes. In this study, self-powered polarization-sensitive 3dPDs based on heterostructures have been demonstrated for the first time through the controllable rolling assembly and crafted electrode design of tubular MoS2/GaAs/InGaAs heterostructure. A dichroic ratio of 1.39 is measured under 650 nm wide-angle omnidirectional incident light, and the underlying polarization mechanism is clearly elucidated through comparative experiments and simulations, primarily attributed to the uniaxially-strained MoS2 in the self-rolled-up heterostructure. Benefiting from the built-in electric field offered by the heterostructure, the as-fabricated self-powered 3dPD demonstrates a fast response time (τr/τf) of 710/700 µs, which is nearly two orders faster than the self-powered polarization-sensitive tubular 3dPD based on homostructures, meanwhile achieving a responsivity of 86 mA W−1. Significantly-improved polarization-sensitive photodetection performance of heterostructure-based self-powered 3dPDs can be expected via introducing functionalized 2D materials and semiconductors, thus making tubular 3dPDs great application prospects in low-power consumption, fast recognition, and target tracking.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These technologies are promising solutions for various real-world applications, including indoor, underwater, vehicular, and IoT systems. However, conventional OWC systems are constrained by their bulky structures and fixed optical properties, which limit their ability to provide on-demand communication services and integrate with on-chip technologies. Therefore, the demand for ultrathin, reconfigurable devices with real-time adaptability is becoming increasingly urgent to ensure efficient and reliable communication. Here, this study introduces a fluid-induced reconfigurable, polarization-insensitive metasurface to enhance the performance and flexibility of OWC networks. A key feature is its ability to adjust diffracted light to meet communication requirements, irrespective of the polarization state of the incident light. This metasurface utilizes infrared light at a wavelength of 1550 nm to enhance signal transmission and reduce environmental interference. In a proof-of-concept, a 0.5 mm × 0.5 mm metasurface is fabricated, and its focal length variation is verified in three different fluidic environments: Air (n = 1), Polymethyl methacrylate (PMMA) (n = 1.491), and AZ-GXR (n = 1.602).
