Among them, optical encryption is an excellent candidate due to its unique features such as high‐speed parallel processing, low power consumption, and abundant degree of freedom. Despite recent advances of nanophotonic devices that have promoted the development of optical encryption techniques, the realization of high‐security and high‐capacity all‐optical 3D image encryption remains an ongoing challenge due to the absence of a suitable 3D nanophotonic device. Here, the study constructs an integrated 3D carbon dot (CD) array through direct laser writing (DLW) in a solid‐state polymeric material and demonstrate its parallel manipulation and selective transmission characteristics of multiple orbital angular momentum (OAM) beams. Benefitting from the photo‐luminescence responses of the CDs and theoretically unlimited helical mode indices of OAM beams, a high‐security and high‐capacity all‐optical encryption platform by integrating the 3D CD array and an OAM‐multiplexing hologram is developed. Through the platform, the encryption and decryption of a series of multi‐plane 3D images can be realized without additional digital post‐processing. The results provide a novel inspiration for nanophotonic devices‐based all‐optical encryption and advance the development of optical encryption applications harnessing light's OAM dimension.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"106 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluorescence molecular tomography (FMT) aims to overcome these constraints by generating 3D fluorophore maps through model‐based reconstruction. However, background fluorescence, resulting from non‐specific probe binding and autofluorescence, significantly compromises FMT image quality with severe artifacts. Solution decomposition FMT (SD‐FMT) is introduced, an innovative reconstruction method that employs an advanced prior model to decompose the solution into multiple stochastic components. The reformulated inverse problem is resolved using a hybrid projection method (HPM), ensuring robustness and efficiency. Validated through exhaustive phantom and in vivo proof‐of‐concept studies, SD‐FMT represents a paradigm shift in FMT reconstruction, with significant implications for expanding applications in preclinical research and advancing fluorescence‐guided surgical navigation.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"95 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the passive metasurfaces, once fabricated, lack dynamic tunability, while existing metasurface‐based stealth designs are primarily based on planar metasurfaces, which severely limit their applicability to curved platforms. In this work, an innovative strategy is proposed for conformal active metasurface (CAM) by integrating 3D‐printed curved substrates with voltage‐programmable 2‐bit phase coding. This design enables dual‐functional tunable EM waves functions in adaptive beam steering for radar cross‐section (RCS) enhancement and in vortex wave generation with orbital angular momentum (OAM) for communication from 9.3 to 10.5 GHz. Simulation and experimental results demonstrate that the CAM can deflect incident waves with angles ranging from 0° to 50° in the beam‐steering mode and achieve preset reflection directions with a pointing accuracy of better than ±2°. The RCS is reduced by more than 10 dB along the incident direction, while it is enhanced by up to +8.9 dB in the preset reflection direction, effectively enabling wide‐angle radar stealth for both illusionary stealth and camouflage. In the OAM mode, the CAM generates vortex beams with OAM at 150 mm, which can effectively increase the spectral efficiency of wireless communication systems. This promising design paves the way for the development of intelligent metasurfaces with enhanced serviceability and flexibility, offering tremendous potential for applications in communication, stealth, and other multifunctional smart metadevices.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"101 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, an efficient scheme featuring multiple Fabry–Pérot modes with equal intervals and uniform intensity is presented to implement a resonance interaction enhancement of molecular fingerprints with long‐awaited precision and flexibility. This technique constructs uniform resonant probes across the entire spectral range to reveal molecular coupling effects via frequency‐selective amplitude attenuation, enabling both qualitative and quantitative detection of L‐tyrosine with a detection limit of 0.11 µg mm−2. This is an inaugural experimental achievement of quantitative THz trace fingerprint detection with dual capabilities of achieving ultra‐broadband and high‐efficiency. Significantly, the technology enables direct identification of molecular absorption signatures from the transmitted multiple Fabry–Pérot modes using wavelet denoising algorithms, eliminating cumbersome data postprocessing and redundant testing procedures.

Although photonic bound states in the continuum (BICs) can suppress radiative losses to enhance Q‐factors, current plasmonic chiral quasi‐BIC designs remain limited to 2D configurations or infrared regimes, which limits the control over optical chirality and resonance linewidth. Here, 3D symmetry‐broken plasmonic metasurfaces operating in the visible spectrum are introduced, enabled by a nanofabrication breakthrough integrating thermal scanning probe lithography (t‐SPL) and anisotropic etching. This methodology achieves nm‐scale height control in out‐of‐plane architectures, enabling chiral quasi‐BIC resonances with independent tuning of CD (0–0.6) and Q‐factor (10–55)—establishing unprecedented performance benchmarks in chiroptical plasmonic metasurfaces. Crucially, the 3D height asymmetry parameter independently governs CD intensity, while BIC‐engineered symmetry breaking enables precise Q‐factor tuning via radiative loss modulation. Hyperspectral CD mapping reveals that the decoupled control mechanism originates from orthogonalized multipolar interactions between in‐plane lattice modes and out‐of‐plane plasmonic couplings. By resolving long‐standing fabrication challenges in 3D metasurfaces, a universal framework is established for applications demanding concurrent chiral selectivity and ultraconfined fields, including chiral nanolasers, enantioselective nonlinear systems, and quantum emitter interfaces with spin‐photon interactions.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"27 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diffractive Optical Neural Networks (DONNs) have recently been demonstrated to efficiently recover images with scattering distortions using coherent light in terahertz spectrum [eLight, 2022, 2(1):4]. However, the study [Optica, 2024, 11(12):1742] has demonstrated that DONN designed for coherent light may not function optimally with low coherent sources. Consequently, the performance of DONNs in image‐based reconstruction tasks under visible and incoherent light requires further investigation. For this purpose, a three‐layer DONN is constructed to reconstruct images occluded by unknown random diffusers under coherent/incoherent visible light. The results show that the Pearson correlation coefficient (PCC) of the coherent DONNs reconstructed images can reach 0.863–0.971 for diffuser correlation lengths of (: a single neuron size of 8 µm); when of , the PCC of the incoherent diffractive optical neural networks (IC‐DONNs) reconstructed images can reach 0.861–0.899. It is found that the dynamic phase modulation mechanism introduced by randomly generated diffusers during network training enhances the adaptation of coherent DONN to spatial coherence variations of the light source. It is believed that these findings will advance the application of DONN for imaging under natural environmental conditions.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"100 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional implementations typically necessitate complex optical assemblies, temporal multiplexing strategies, and specialized active illumination sources, imposing fundamental limitations on system miniaturization and practicality. Drawing inspiration from human visual perception, particularly disparity images and optical structures, a metasurface capable of 4D imaging is demonstrated through single‐shot acquisition. Leveraging polarization multiplexing principles and the non‐diffracting, self‐accelerating properties of Airy beams, the metasurface produces spin‐decoupled point spread functions (PSFs) exhibiting horizontal displacement correlated with object depth. This configuration enables the generation of disparity‐equivalent images in the left‐ and right‐handed circular polarization channels. By combining these with the proposed image restoration and depth retrieval algorithms, 4D imaging encompassing 3D imaging and polarization analysis is achieved. This compact multidimensional imaging platform demonstrates significant potential to advance machine vision and autonomous driving applications while offering foundational insights for further high‐performance imaging system development.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"41 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
