However, recent polariton studies show that cavity linear response can encode nonlinear optical susceptibilities. Here, we demonstrate that this phenomenon is more general: emitter–emitter interactions allow nonlinearities of individual emitters to emerge in the linear response of arrays, without cavities or permutational symmetry. To illustrate this phenomenon, we show linear spectra for coupled heterodimers and linear chains, and demonstrate that Raman features of individual monomers show up as vibrational sidebands of collective resonances. Moreover, tuning Raman‐type anharmonicities enables systematic control of spectral features, establishing a genuine quantum optical effect in molecular aggregates and quantum emitter arrays, which goes beyond mean‐field descriptions in light‐matter interactions.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"1 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Building on this foundation, a multimode Jaynes–Cummings framework has been developed and verified, providing an accurate description of atom–field interactions in lossy and radiative systems. In this work, we explore the potential of this formalism for nanophotonic applications by modeling representative quantum–plasmonic dynamics. In particular, we present detailed numerical examples for (i) two‐photon interference mediated by a quantum plasmonic beam splitter, and (ii) non‐Markovian dynamics of an atom located in plasmonic antennas and corresponding directional control of out‐coupled single‐photon fields. These results illustrate how the proposed modeling approach can provide quantitative insight into the behavior of plasmonic single‐photon sources and beam‐splitting structures.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"32 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Ultra‐thin metalenses hold transformative potential for next‐generation optics, yet their widespread adoption is severely impeded by the high cost of wafer‐level fabrication. In this paper, 8‐inch wafer‐scale near‐infrared all‐dielectric metalenses are demonstrated by a scalable high‐precision manufacturing scheme that dramatically reduces cost while ensuring exceptional uniformity and performance. Our step‐and‐repeat (S&R) imprinting strategy eliminates the need for costly deep‐UV lithography or large‐area direct‐write tools, reducing master mold costs by over an order of magnitude. Optical characterization confirms diffraction‐limited focusing performance and remarkable consistency across the entire wafer, validating both process robustness and design fidelity. Owing to its compatibility with diverse material systems and standard semiconductor processes, this methodology paves a practical high‐yield pathway toward the commercial deployment of high‐performance metasurfaces for demanding applications, including LiDAR, AR/VR, and aerospace‐grade optics.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"7 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

These characteristics provide an insight to distinguishing the light–matter modes of water which have remained unresolved due to the common assumption of homogeneous broadening. This demonstrates that vibrational polariton formation in aqueous media is dictated by the vibrational heterogeneity that remains spectroscopically distinguishable whenever structural exchange occurs more slowly than the light–matter coupling timescale, establishing water‐in‐salt electrolytes as an ideal platform for disentangling multi‐mode light–matter interactions in molecular liquids.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"51 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 review focuses on two representative types of PSODLs, super‐oscillatory lenses (SOLs) and supercritical lenses (SCLs). Both can generate far‐field focal spots with sizes below the diffraction limit, but they exhibit distinct optical‐field focusing characteristics, and there are trade‐offs among performance parameters. Therefore, this review provides specific guidance for the selection and optimization of PSODLs in accordance with application scenarios. To better promote the practical application of these kinds of lenses, a systematic analysis of typical applications in areas such as super‐resolution imaging, micro/nanofabrication, and high‐precision measurement is provided. Potential extensions of PSODLs to integrated optical imaging systems, optical sensing, particle manipulation, and optical storage are also discussed. Future practical deployment of PSODLs will rely on application‐oriented multiobjective optimization, robust and scalable fabrication, active system integration, and standardized performance evaluation.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"38 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, two‐dimensional (2D) metasurfaces based on coherent lattice coupling exhibit polarization anisotropy and angular dispersion, which lead to phase distortion. Here, three‐dimensional (3D) bulk metamaterials (MMs) functioning as THz attenuators are proposed and experimentally demonstrated based on a de‐latticing strategy inspired by amorphous natural materials. Periodic arrays of cross‐bar meta‐atoms are encapsulated by cyclo‐olefin polymer (COP) as randomly oriented cubic meta‐grains and dispersed within a COP matrix, forming an amorphous composite that eliminates in‐plane coherence. The fabricated samples exhibit band‐selective and thickness‐tunable attenuation with a smooth refractive‐index variation across 0.3–0.4 THz. Compared with the 2D metasurface, the dispersion slope decreases from 8.37 to 0.36 at the resonant frequency, indicating an order‐of‐magnitude suppression of phase dispersion. The attenuation scales continuously with thickness owing to incoherent resonant scattering from randomly oriented dipoles, providing a practical pathway to thickness‐dependent and band‐selective response. This work demonstrates an isotropic, low‐dispersion, and thickness‐tunable 3D bulk MMs THz attenuator that overcomes the polarization anisotropy and strong dispersion of conventional 2D attenuators, offering a practical pathway toward integrated THz photonic systems.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"35 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Numerical results show that STOVs with a nonzero longitudinal OAM component exhibit significant vortical dichroism (VD), whereas those with purely transverse OAM do not. Mechanistically, transverse OAM's zero net optical chirality density and collapsed spatial energy flow vortex lack the requisite torque and asymmetric multipolar excitations to drive chiral responses. Furthermore, it is found that the larger topological charges and tighter spatiotemporal scales significantly enhance the VD.
