Perovskite, with its advantages of high carrier mobility and tunable band gaps, have become an ideal alternative to silicon-based materials. This paper systematically reviews the progress in the patterned fabrication techniques and device construction of perovskite photodetectors across various dimensional material systems. First, it introduces five mainstream patterned fabrication methods for perovskites: template-confined growth, inkjet printing, vapor deposition, seed-induced growth, and conventional photolithography. Then, the latest research on image sensors based on perovskite materials in different dimensions is discussed. Following this, the paper highlights two promising application directions with great development potential: flexible wearable devices and electrochemical vision systems. Finally, the challenges and potential solutions for the future development of patterned perovskite photodetectors are presented to guide the development of high-performance perovskite optoelectronic devices.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"23 1","pages":"355"},"PeriodicalIF":0.0,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rapid carrier recombination in these optoelectronic synapses results in a poor number of conductance states and a low linear weight update protocol, consequently degrading the image recognition accuracy of DUV NVSs. This work proposes a type of cascade heterojunctions capable of finely tuning the dynamics of photogenerated carriers, utilizing aluminum interdigital electrodes sandwiched between tin-doped Ga2O3 and oxygen-deficient hafnium oxide (GTO/Al/HfOx) films. The built-in fields at the GTO/HfOx heterojunction and the Al/HfOx hole Schottky junction interfaces facilitate the separation of photogenerated carriers and the subsequent trapping of holes by the oxygen defects in the HfOx, respectively. The GTO/Al/HfOx optoelectronic synapses exhibit an ultrahigh responsivity of over 104 A/W and a large photo-to-dark current ratio of 6 × 105, which results in exceptional synaptic plasticity with unprecedented 4096 conductance states and excellent linearity with a fitting coefficient of 0.992. These attributes enable the GTO/Al/HfOx optoelectronic synapses to execute logical operations with fault-tolerance capability and to achieve high-accuracy fingerprint classification. The innovative cascade heterojunctions design, along with the elucidated carrier dynamics modulation mechanism, facilitates the development of DUV NVSs.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"99 1","pages":"354"},"PeriodicalIF":0.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While significant progress has been made in improving VCSEL performance, the role of cavity geometry in optimizing key optical characteristics remains insufficiently explored. This study systematically examines how distinct cavity geometries-circular, square, D-shaped, mushroom-shaped, and pentagonal-affect both the static and dynamic properties of broad-area VCSELs. We analyze their effects on optical power, multimode behavior, beam profile, spatial coherence, and polarization dynamics. Our results show that breaking the continuous rotational symmetry of the cavity effectively increases gain utilization and power, changes the multimode lasing characteristics, shapes the beam, and modifies the polarization. Notably, the pentagonal VCSEL exhibits more than twice the optical power density of its circular counterpart. It also supports the highest number of modes and the fastest mode dynamics, driven by strong mode interaction. These properties make it a strong candidate for high-speed entropy generation. Mushroom-shaped VCSELs demonstrate high power and low spatial coherence, making them ideal for speckle-free imaging and illumination applications. Meanwhile, D-shaped VCSELs provide the most stable polarization and controllable multimode behavior with high power, showcasing their potential for applications that require stable and low-coherence light sources. This study offers a comprehensive analysis of the impact of cavity geometry on VCSEL performance, which provides insights for optimizing VCSEL designs tailored to diverse applications that require distinct properties with broad applicability to advanced imaging, sensing, optical coherence tomography, high-speed communication, and other photonic technologies.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"92 1","pages":"344"},"PeriodicalIF":0.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, it is found that the non-separability of vectorial structured light remains invariant when transmitting through atmospheric turbulence. This discovery offers a potential solution for turbulence-resilient communications-encoding based on the non-separability of vectorial structured light. To achieve such turbulence-resilient communications, efficient detection of the non-separability of vectorial structured light is essential, which acts as the receivers of such communication systems. So far, traditional non-separability detection schemes usually rely on bulky SLMs or DMDs, facing inherent trade-offs between single-shot capability and system compactness. In addition, the detection of mode-resolved non-separability contributions of vectorial superposition states has not yet been accomplished. Here, we propose and experimentally demonstrate a coherent detector to characterize the non-separability of vectorial structured light based on off-axis digital holography, which overcomes the limitations of traditional approaches by digitally decomposing spatial modes. Our approach may pave the way for turbulence-resilient optical communications based on non-separability coding methods and bring new insights into non-separability measurement.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"4 1","pages":"343"},"PeriodicalIF":0.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional OAM multiplexing systems operating solely in the spatial domain face significant challenges, including increased system complexity, inter-modal crosstalk, and limited scalability. Recent advances have explored hybrid multiplexing schemes combining OAM with wavelength or polarization degrees of freedom, demonstrating Pbit/s level transmission capacities. However, these systems predominantly rely on continuous-wave lasers and external modulators, which constrain their applicability in challenging environments, whereas pulsed lasers provide superior peak power, enhanced transmission robustness, and the potential for implementation of OAM lasers, which generally emit pulsed OAM beams. Here, we report an OAM-based spatiotemporal multiplexing (OAM-STM) technique that synergistically implements pulsed OAM beams with a diffractive deep neural network (D2NN) and optical fiber delay lines to project spatial mode information into the temporal domain. This approach leverages the full potential of pulsed laser sources by activating the underutilized time dimension, thereby overcoming the repetition-rate bottleneck and enhancing channel throughput. We experimentally demonstrate an OAM-based spatiotemporal demultiplexer achieving demultiplexing speed limited only by the bandwidth of the photodiode if OAM generation is fast enough. In the meantime, the architecture is intrinsically compatible with high-repetition-rate OAM sources, offering the entire system the scalability to GHz rates. This work establishes a foundational framework for high-speed, all-optical, and high-capacity OAM-STM systems, with promising implications for free-space optical communication, underwater communication links, and other complex environments.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"41 1","pages":"342"},"PeriodicalIF":0.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite a broad selection of functional neuroimaging tools for multi-scale brain interrogations, no methodology currently exists that can discern responses from neural and glial cells while simultaneously mapping the associated hemodynamic activity on a large scale. We present a hybrid multiplexed fluorescence and magnetic resonance imaging (HyFMRI) platform for measuring neuronal and astrocytic activity registered to concurrently recorded brain-wide hemodynamic responses. It features a fiberscope-based imaging system for multichannel fluorescence and optical intrinsic signal recordings and a custom surface radiofrequency coil, which are incorporated into the bore of a preclinical magnetic resonance imaging (MRI) scanner. We used HyFMRI to study peripheral-stimulus-evoked brain responses in mice differentially labeled with RCaMP and GCaMP genetically-encoded calcium indicators. Stimulation-evoked neuronal responses displayed the fastest kinetics and highest activation amplitude followed by astrocytic signals and the hemodynamic responses simultaneously recorded with functional MRI. In addition, the activation traces from neurons and astrocytes exhibited high linear correlation, thus providing direct evidence of astrocytic mediation in neurovascular coupling. This newly developed capacity to capture cell-type-specific calcium signaling alongside whole-brain hemodynamics enables the simultaneous investigation of neuro-glial-vascular interactions in health and disease. HyFMRI thus expands the current neuroimaging toolbox for a wide range of studies into synaptic plasticity, neural circuitry, brain function and disorders.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"27 1","pages":"341"},"PeriodicalIF":0.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, 4-5-μm compact fiber laser sources remain a significant technological challenge due to the lack of MIR fibers with good chemical stability, thermal stability, high nonlinearity, and low loss. Here, we develop fluorotellurite fibers based on 60TeO2-20BaF2-10AlF3-10Y2O3 (TBAY) glasses with a wide transmission window, demonstrating tunable Raman soliton and dispersive wave (DW) generation beyond 4 µm in centimeter-length fluorotellurite fibers pumped by a 3.54 μm femtosecond laser source. Fluorotellurite fibers with a loss of 0.39 dB/m were fabricated using a rod-in-tube method. The high numerical aperture (NA ~ 1.1@3.5 μm) of TBAY fibers allows the zero-dispersion wavelength (ZDW) to be tuned over a wide range by varying the core diameter of the fibers. The dispersion-engineered TBAY fibers with a core diameter of 6.5 μm enabled 4584 nm Raman soliton generation, while fibers with a core diameter of 3 μm enabled 4177 nm DW generation. We conducted detailed experiments to investigate the influence of pump power and fiber length on SSFS and dispersive wave dynamics. Theoretical analysis and numerical simulations based on the generalized nonlinear Schrödinger equation corroborate the experimental results.
