However, most existing approaches focus on image-to-image mapping or physics-constrained reconstruction, making it difficult to directly characterize the TIE's continuous inverse operator in function spaces. In contrast, operator-learning methods tailored to this problem remain underexplored, and existing neural operators may still be limited by discretization-grid dependence and spectral aliasing during cross-resolution inference. To address these challenges, we propose a TIE neural operator, termed TIENO, which learns the inverse TIE operator from the in-focus intensity and axial intensity derivative to the phase distribution by preserving continuous-discrete equivalence in band-limited function spaces. TIENO incorporates band-limited spectral regulation and frequency-domain channel attention into an encoder-decoder architecture, thereby suppressing unresolved high-frequency components and enhancing the representation of phase-relevant features. Numerical evaluations on simulated datasets demonstrate that TIENO achieves high-accuracy phase recovery and maintains stable inference performance at unseen spatial resolutions, while experimental validation on biological cell data further confirms its applicability to practical QPI and shows that it outperforms representative learning-based models and conventional TIE solvers. These results highlight the potential of TIENO for accurate and resolution-flexible TIE-based quantitative phase imaging.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 20","pages":"37576-37593"},"PeriodicalIF":3.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149113336","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}

While conventional metals are commonly used in plasmonic metasurfaces, metallic transition-metal dichalcogenides with high carrier densities and infrared plasmonic response have emerged as attractive alternatives. Here, we demonstrate the mid-infrared TaSe2 plasmonic metasurfaces with periodic hole arrays. It is observed that two plasmonic resonance modes in mid-infrared frequency range are supported in the TaSe2 metasurface. The simulated electromagnetic field distributions reveal that the two plasmonic resonances represent a fundamental (1, 0) mode and a higher-order (1, 1) mode. By increasing the array period, a continuous redshift of the resonance frequency is observed for each mode, consistent with the inverse scaling predicted by the grating coupling condition. The demonstrated results will advance the development of 2D-material-based mid-infrared photonic devices as a promising platform for applications in thermal emission control, molecular sensing, and infrared detection.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 20","pages":"38002-38010"},"PeriodicalIF":3.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149113412","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}

Within an effective-mass/envelope model, we quantify how structural parameters and static fields reshape level intervals and intersubband dipole couplings, thereby controlling SHG amplitude and lineshape. A magnetic field compresses the envelope and tends to equalize subband spacings, damping asymmetry-driven SHG at high fields, whereas an electric field tilts the well, breaks inversion symmetry, and can realign resonances; the trends are governed by the detuning between one- and two-photon channels and by the strength of the dipole overlap chain. Building on these insights, we train a shallow feed-forward network that maps the electric and magnetic fields directly to the SHG peak, achieving near-unity R2 with very low RMSE on both medium- and small-sample datasets, and retaining accuracy over modest extrapolation, enabling rapid parameter selection without repeated eigenproblem and susceptibility evaluations. The parameter ranges and model knobs are qualitatively linked to GaAs/AlGaAs controls, providing a practical route from symmetry tuning to SHG prediction in experimentally relevant regimes.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 20","pages":"36775-36786"},"PeriodicalIF":3.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149112155","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, it remains challenging to achieve nonreciprocal entanglement characterized by stability and robustness against environmental fluctuations. Here, we propose a universal nonlinear mechanism to engineer magnetic-free nonreciprocity in dissipative optomechanics by utilizing bistability, a phenomenon ubiquitous across nonlinear physical systems. By dynamically encircling the nexus of bistability, a cusp converged by the bistable surfaces, we obtain nonreciprocal displacement and then utilize it to achieve robust nonreciprocal entanglement. Owing to the unique landscape of bistability, our nonreciprocal displacement and entanglement exhibit stability and robustness through closed-loop operations. Our work presents a foundational framework for leveraging nonlinearity to achieve nonreciprocal quantum information processing. It paves new avenues for exploring nonreciprocal quantum information processing and designing backaction-immune quantum metrology with nonlinearity.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 20","pages":"37152-37163"},"PeriodicalIF":3.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149112923","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 field-propagation and wavenumber-domain FFT analyses show that the lateral offset redistributes the relative spectral contributions of different optical-path-difference components. At the same time, the HCF length modifies accumulated phase and the effective-index-difference distribution. Under axial loading, selected spectral features exhibit linear blue shifts over a model-estimated HCF strain range of 0-4800 µε, with R2 values of 0.974-0.994 and responsivities of -0.49 to -0.38 pm/µε. Opposite bending orientations produce reversed wavelength-shift polarities. The positive and negative orientations show monotonic nonlinear responses over 0.003-0.17 mm-1 and 0.01-0.10 mm-1, with range-averaged responsivities of 7.44 and -20.61 nm/(mm-1), respectively. A full 360° rotation further yields sinusoidal wavelength modulation, demonstrating azimuth-dependent spectral encoding.
