However, laser probes suffer from low hit rates and accuracy due to the weak signals of aerosols and their susceptibility to interference. Specifically, LIPP analyzes aerosols by breaking them down to obtain elemental information, often ignoring the inherent surface information. Herein, optical trapping-assisted second harmonic generation (SHG) was utilized to investigate small amounts of aerosols. The results demonstrate that optical trapping effectively controlled the aerosol count, from a few tens to single particles. Additionally, the adsorption free energy of trans-4-[(4-dimethylamino)styryl]-1-methylpyridinium iodide molecules on the bioaerosol surface was determined. Furthermore, optical trapping-assisted LIPP detected principal elements (K, Ca, Na, and Mg) in the bioaerosol. The homologous heterogeneous information (spectra, sound (shock wave images), and plasma images) of the plasma was analyzed, and multiple signals were complementarily corrected to enhance the classification accuracy of LIPP analysis. Finally, to enhance LIPP and SHG data mining, we proposed an artificial intelligence (AI)-driven adaptive multimodal attention fusion network, which improved the classification accuracy of 13 bioaerosols from 83% to 96%. This work establishes a highly sensitive laser probe detection platform that synergistically analyzes surface adsorption and internal element components, paving the way for future single-bioaerosol detection and alarm systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"24 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798190","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}

In this study, reconfigurable and polarization-dependent tunable MLAs are reported by multifield-based assembly and modulation of the optical anisotropy lens units. Nematic liquid crystal (NLC) droplets are assembled into uniform and large-area MLAs within designed periodic acoustic potentials, obtaining reconfigurable structures and tunable array periods. In addition, droplets containing dispersed ferroferric oxide (Fe3O4) nanoparticles (NPs) are produced, endowing the magnetic control of the LC’s spatial alignment and thus achieving polarization selectivity. The combination of acoustic and magnetic modulation allows high flexibility in converting polarization-selective imaging capability and breaks the coupling between translation and rotation, enabling individual rotation by the magnetic field and translation by the acoustic field, respectively. Further modulation in acoustic signal amplitude can also switch the ability to polarization-selective imaging on and off. With such features, these MLAs are proven to be capable of selectively obtaining images of objects with different polarization states. This strategy offers a new route in optical tunable microlens and MLA fabrication and modulation, with the advantages of being robust, flexible, and low cost, exhibiting potential in miniaturized optical systems, integral imaging, and three-dimensional displays.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"24 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798189","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 power splitters, such as Y-branches, directional couplers, and multimode interferometers rely on nonresonant waveguiding effects, like index matching, mode coupling, and interference, which limit their design freedom for arbitrary and multiport light splitting in ultracompact footprints. Recent advancements in dielectric metasurfaces have opened new possibilities for compact on-chip devices. Here, based on Huygens’ meta-waveguides, we numerically and experimentally demonstrate efficient 1 × N (N = 2,3,4) power splitting in ultracompact footprints with low insertion loss. Particularly for 1 × 2 splitters, arbitrary power splitting can be realized by adjusting the relative positions of Huygens’ resonators without requiring full structural reoptimization. These designs utilize efficient light manipulation through nanoantennas and have potential for large-scale PICs, including applications in optical computing.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"12 4","pages":"1919–1925 1919–1925"},"PeriodicalIF":6.5,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832820","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}

Although most studies of strong coupling have focused on the characteristics of intensity spectra, the behavior of the phase of polaritons remains comparatively unexplored. In this work, we employ metasurfaces that support optical modes to couple them strongly with intermolecular vibrations in α-lactose at THz frequencies, forming vibro-polaritons. Using terahertz time-domain spectroscopy (THz-TDS), we examine this strongly coupled system in both amplitude and phase and use the phase topology as an indicator for such coupling. In addition, we explore the group index in the weak and strong coupling regimes. We observe the decrease in the negative group index associated with the anomalous dispersion of the resonant modes as a function of the coupling strength. This work reveals previously hidden insights into temporal and enhanced light–matter interactions in strongly coupled systems and highlights the relevance of the phase in the analysis of these systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"37 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776168","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}
