Leveraging its wide bandwidth, optical computing can significantly accelerate computational speed. Moreover, it can exploit multiple multiplexing dimensions, such as time and wavelength, for multichannel parallel computing. Modes, theoretically infinitely multiplexed dimensions, hold promise for significantly increasing channel capacity in optical computing. However, research in this domain remains limited at present. Here, we have designed and fabricated a parallel convolution processor based on a multimode core on a thin-film lithium niobate (TFLN) platform. Utilizing multimode multiplexing and multimode computing cores, we achieved parallel convolution computation across four channels, demonstrating the effect of image convolution.

However, it remains a significant challenge to achieve super-resolution imaging at depth in opaque materials. In this study, we present a super-resolution microscopy technique for imaging hidden fluorescent objects through scattering media, started by exploiting the inherent object replica generation arising from the memory effect, i.e., the seemingly informationless emission speckle can be regarded as a random superposition of multiple object copies. Inspired by the concept of super-resolution optical fluctuation imaging, we use temporally fluctuating speckles to excite fluorescence signals and perform high-order cumulant analysis on the fluctuation, which can not only improve the image resolution but also increase the speckle contrast to isolate only the bright object replicas. A super-resolved image can be finally retrieved by simply unmixing the sparsely distributed replicas with their location map. This methodology allows one to overcome scattering and achieve robust super-resolution fluorescence imaging, circumventing the need for heavy computational steps.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"12 3","pages":"1308–1315 1308–1315"},"PeriodicalIF":6.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143641193","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}
