However, the instability of Sn perovskites prevents the postprocessing of the film after deposition, making its integration in two-dimensional optical architectures challenging. In this article, FASnI3 polycrystalline thin films are successfully integrated with polymeric diffractive gratings under cost-effective and industrial compatible technology. The gratings are fabricated under holographic techniques, allowing patterning on large areas (≈1 cm2) and the posterior deposition of the perovskite films or cladding layers. The grating period demonstrated to be an adequate tuning parameter to control the amplified spontaneous emission (ASE) properties. Notably, the overlap of the mode with the emission band represents a suitable mechanism to selectively enhance the generation of the ASE (tuned device) above a moderate threshold of 100 μJ/cm2 and extract the random lasing lines created on the grains of the film (detuned device). These results represent a significant advance on Sn-perovskite-based optical sources, offering cost-effective technology for next-generation photonic applications.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"42 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114472","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}

This allows vastly more design freedom than imposing continuous axisymmetry while avoiding the compromises of locally periodic approximation or scalar diffraction theory. Using a GPU-accelerated finite-difference time-domain solver in cylindrical coordinates, we perform full-wave simulation and topology optimization within each supra-wavelength zone. We validate our approach by designing millimeter- and centimeter-scale polyachromatic, 3D freeform metalenses, which outperform the state-of-the-art. By demonstrating the scalability and resulting optical performance enabled by our “zoned discrete axisymmetry” and supra-wavelength domain decomposition, we highlight the potential of our framework to advance large-scale metaoptics and next-generation photonic technologies.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"38 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104239","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}

However, the complexity and cost associated with state-of-the-art systems like lattice lightsheet microscopy and oblique plane microscopy often limit their accessibility to specialized laboratories. This Review explores an emerging class of microscopy techniques that utilize line-scan illumination combined with rolling shutter detection, offering a simpler and more accessible alternative that still maintains high imaging performance. These methods extend the principles of traditional confocal microscopy by illuminating the sample along a line and using a camera’s rolling shutter as a virtual slit to enhance optical sectioning and resolution. Various implementations are discussed to highlight their unique benefits and applications. In addition, this Review provides a comprehensive comparison between implementations and showcases latest systems that gain unique capabilities enabled via clever use of rolling shutter line-scanning. By making high-resolution imaging more accessible, rolling shutter line-scan microscopy is prone to empower a wide range of scientists to explore intricate cellular dynamics and structures, paving the way for new discoveries in the life sciences.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"78 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088087","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, we establish an integrated FPA chip based on the electro-optical (EO) effect of thin-film lithium niobate (TFLN) to access these outstanding performances. By leveraging the advantages of the EO effect of TFLN, we showcase an ultrafast operating speed of 25.9 ns and an ultralow power consumption of 35.8 nJ/π, which are 3 and 2 orders of magnitude smaller than those of conventional FPAs, respectively. Our experimental results demonstrate a two-dimensional (2D) beam steering with a field of view (FoV) of 1.48° × 1.95°, a beam divergence of 0.036° × 0.043°, and a background suppression ratio exceeding 20 dB. Furthermore, we present the elimination of blind zones in one direction and the potential application of laser projection of proposed EO FPA.

Cathodoluminescence (CL) spectroscopy has the potential to analyze the emission properties of materials with nanometer spatial resolution far beyond the diffraction limit of light. However, due to the lack of excitation wavelength selectivity, it is often challenging for CL to discriminately evaluate multiple emission processes in emitter–resonator systems. Especially in cases where the optical resonators can enhance not only the emission but also the excitation of the emitters, quantification of the light emission enhancement independent of the excitation method becomes more complex. Here, we propose an application of Hanbury Brown–Twiss (HBT) interferometry that is sensitive to the excitation efficiency of CL. We used HBT-CL as well as CL spectroscopy to evaluate the light emission of halide perovskites enhanced by plasmonic resonators and found that the enhancement can be quantified as an increase in coincidence counts. The plasmonic resonator caused almost no change in the second-order autocorrelation function, confirming that the effect of the resonator on electron beam excitation was negligible. Our results suggest that HBT-CL is effective for the quantitative evaluation of light emission enhancement in various emitter–resonator systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"92 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144103994","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}

Correspondingly, ultrafast imaging methods must realize continuous recording with ultrahigh frame rates and numerous frames in a single shot. To overcome this challenge, spectral-temporal ultrafast photography, which uses spectral dimensions of an observing pulse to detect the temporal dimensions of an ultrafast process, has earned excellent performance. This rapid-developing field holds advantages over other single-shot ultrafast imaging methods with nonreciprocal detecting dimensions using unique spectral-temporal reciprocities. Until now, spectral-temporal ultrafast photography has been capable of hundreds of frames in single-shot detection, a detecting window from femtoseconds to nanoseconds, and tens of femtoseconds in temporal resolution. Here, we comprehensively survey the state-of-the-art spectral-temporal ultrafast imaging methods. Two main steps, the generation of the spectral-temporal observing pulse and the restoration of the spectral image sequence, are discussed.

Photonic convolutional neural network (PCNN) offers the capability to directly process optical data and exhibits the characteristics of high parallelism, ultrafast processing speeds, and low energy consumption. However, existing PCNN schemes are limited by additional controllers, high-precision configuration, and complex alignment devices. A potential solution is to design a programmable fiber weight bank for PCNN, which supports all-optical in-fiber calculation. Here, we integrate Ge1.4Sb1.22Se3.96Te1 (GSST) on the lateral facets of commercial seven-core optic fibers as a programmable fiber weight bank. The coupling efficiency between the GSST and fiber is enhanced by employing side-polishing techniques. Each GSST cell can be optically altered to exhibit a 16-level weight, depending on the power of the light pulse within the fiber. The fiber weight bank has reconfigurability, parallel computing capability, and can be easily scaled. In addition, a fiber-PCNN is constructed to demonstrate digital recognition with an accuracy of 90.0% (theoretically 91.6%), which combines the calculative capabilities of PCNN with the merits of a fiber, thereby providing a novel solution for remote all-optical computing.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"49 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946291","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}
