Here, we numerically propose a dual-mode EO spatial modulation scheme enabled by barium titanate guided-mode resonance (BaTiO3-GMR) combined with spatial filtering. A SiN photonic crystal structure integrated with a continuous BaTiO3 thin film uses GMR to convert weak electrically induced refractive index perturbations into pronounced complex reflection changes. To overcome the intrinsic amplitude-phase (AP) coupling of single resonant pixels, a two-pixel coherent field synthesis strategy expands the accessible complex field state space, enabling programmable joint AP encoding. Amplitude-type and phase-type trajectories are then selected as two representative constrained modes via 4f spatial-filtering readout. The numerical model yields a broad range near amplitude-only modulation (0 to 0.668) and phase modulation exceeding 2.443 rad. Simulations using MNIST handwritten digits further evaluate 2D amplitude and phase pattern reconstruction. These results establish a simulation-based proof of concept for dual-mode amplitude and phase modulation and provide a numerical basis for future development of programmable optical modulation systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"484 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091326","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 present DrosoScope: a single-objective light-sheet microscope customized for in vivo imaging of adult flies and optimized for maximum resolution. With it, we imaged the axonal projections of small lateral ventral neurons (s-LNvs) in intact adult flies. We imaged the plasma membrane, cytoplasm, mitochondria, and dense-core vesicles with high spatial resolution of up to 310 nm, lower photobleaching than confocal microscopy, lower invasiveness and reduced sample-mounting complexity than alternative light-sheet technologies, and without relying on potentially phototoxic pulsed infrared lasers.

Here, we demonstrate a few-layer graphene (FLG) heater enabled high precision nonvolatile photonic device based on Sb2Se3 phase-change material. By investigating the modulation mechanism of the FLG heater, we achieve precise control over the phase-change photonic device. Combined with a strip-segmented device structure, 101 highly uniform and distinct optical states are realized. Benefiting from the more efficient modulation of phase-change photonic devices by the FLG heater, a total phase shift of 4.5π is achieved over a 30 μm length of Sb2Se3, corresponding to a phase modulation efficiency of 0.15π/μm. This work provides a feasible solution to achieve high precision and high phase modulation efficiency in photonic devices, lays a foundation for more accurate and highly integrated photonic computing systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"55 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091267","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}

Local reflectarrays achieve high reflection efficiency but lack spectral control, while nonlocal metasurfaces support high-Q quasi–bound states in the continuum (q-BICs) with tailorable narrowband responses but suffer from an intrinsic 25% efficiency limit. By combining nonlocal resonances with a mirror-backed cavity, our design achieves narrowband, spin-dependent beam steering with efficiencies above 93% and tailorable resonant frequency, Q-factor, and deflection direction. We demonstrate with coupled mode theory that, by leveraging a self-coupling mechanism of the resonant metasurface through the reflection of the mirror, we achieve control over the amplitude and phase of reflected light at a fixed frequency. We extend these results to show nonlocal metalenses with resonant-exclusive and spin-dependent focusing. These results position hybrid nonlocal reflectarray metasurfaces as a multifunctional platform for efficient, spin-multiplexed imaging, secure optical communication, and quantum photonics.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"7 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091325","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 propose to suppress this bottleneck at its origin by using a one-dimensional (1D) gold atomic chain as an atomic-scale quantum conductor. Density-functional-theory-parameterized nonequilibrium Green’s function calculations show that resonant tunneling through a dz2-dominated ballistic channel suppresses electronic partition noise and generates a sub-Poissonian current. The same 1D spectrum, through discrete molecular levels and van Hove singularities, suppresses elastic tunneling while opening a resonant inelastic channel, yielding an intrinsic plasmon-excitation efficiency ηinel of about 80%. Coupling this quiet, high-yield electron flow to a nanometer-scale plasmonic antenna enables antibunched electroluminescence with a projected external photon-generation efficiency ηEQE ≈ 60% and a high photon purity (g(2)(0) ≈ 0). These results identify quantum-statistical engineering of electron transport as a route to electrically driven nonclassical light at the atomic limit.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"165 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091327","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 investigate carrier cooling dynamics in mono- and bilayer graphene using mid-infrared pump pulses (0.22 to 0.73 eV) and terahertz probe pulses. We uncover a pronounced, reproducible, and nonmonotonic dependence of the carrier relaxation time on excitation photon energy. Within a narrow spectral window from 0.42 to 0.48 eV, the carrier lifetime increases by nearly an order of magnitude compared to the few-picosecond cooling observed at lower and higher excitation energies. The observed excitation-energy dependence is consistent with a hot-phonon bottleneck scenario in which the accumulation and reabsorption of nonequilibrium optical phonons suppress the energy transfer to the lattice. A phenomenological coupled carrier–phonon model supports this interpretation. These findings reveal a previously unreported excitation-energy dependence of hot-carrier cooling in graphene and provide new insight into nonequilibrium carrier–phonon interactions near the optical-phonon bottleneck.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"20 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091045","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 particular, molybdenum disulfide (MoS2) has emerged as a versatile 2D material platform for many optical and optoelectronic applications due to its high refractive index, large surface-to-volume ratio, and tunable bandgap. In this work, the integration of MoS2 layers on a side-polished optical fiber with a D-shaped cross-section has been demonstrated using a low-cost and scalable inkjet printing technique. The MoS2-integrated optical fibers are shown to offer strong wavelength-dependent light-matter interactions that can be controlled by the thickness of the 2D material, allowing for tuning of their operation across the entire telecom band. Using a printed device with a MoS2 layer thickness of 30 nm, designed to exhibit a resonance-enhanced transmission dip at wavelengths of ∼1.50 μm, a refractive index sensor has been demonstrated using saline solutions. The experimental results have been verified via numerical simulations, confirming the sensitivity and flexibility offered by the 2D material structures. These results indicate that inkjet-printed MoS2 optical fiber devices are suitable for the development of large-scale sensing networks.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"42 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090744","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}
