Here, we investigate the emergence of effective optical gauge fields in anisotropic Fabry-Pérot cavities, resulting from the coupling between cavity modes with different polarization. As an example, the intrinsic biaxial anisotropy of the intracavity material induces an effective optical gauge field, manifesting as a transition from the optical spin Hall effect to Zitterbewegung of light at different frequencies. The simulation results confirm that the wave packet dynamics, along with the evolution of pseudo-spins driven by anisotropy, can be comprehensively understood using effective optical gauge field theory around unique band crossings. A kind of metamaterial embedded in the Fabry-Pérot cavity is proposed and implemented to realize biaxial anisotropy using effective medium theory, as verified by simulation results and experimental measurements. The emergent effective optical gauge field in a biaxial anisotropic cavity may offer what we believe to be new insights into manipulating light trajectories and designing advanced polarization-sensitive optical devices.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"15423-15437"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144047378","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}

The coupler is designed for the high NA fiber which provides a smaller mode size. In simulations, both TE and TM coupling efficiencies remain above 90% within the wavelength range 1000-2000 nm. In comparison, the TE and TM coupling efficiencies of the conventional single-tip coupler design can drop below 73% over this range. An ultra-high coupling efficiency above 95% is predicted over a bandwidth of 760 nm for the TE mode with the double-tip design, compared to 450 nm for the single-tip design. Experimentally, the highest measured coupling efficiencies for the double-tip and single-tip couplers are 97.1% and 95.7%, respectively. For the double-tip design, the coupling efficiency remains above 90% within the measurement range (1450-1640 nm), as the polarization state changes with the wavelength. These measurements confirm the polarization insensitivity of the double-tip design. In addition, we measure the performance of the double-tip design with a laser source operating at shorter wavelengths. The measured 94% coupling efficiency at 1280 nm indicates the broad bandwidth of the coupler. This work is anticipated to provide a promising foundation for the development of compact efficient photonic devices.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"16253-16262"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144022209","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, existing techniques face significant challenges: chemical labeling is often impractical, and conventional nanoscale imaging methods lack the specificity to resolve chemical bonds within these structures. To bridge this gap, we present an approach named interferometric scattering-guided stimulated Raman scattering microscopy (igSRS), which integrates the bond-selective capacity of stimulated Raman scattering imaging with the high sensitivity of interferometric scattering microscopy. By achieving a substantially enhanced signal-to-noise ratio, igSRS enables the visualization of chemical heterogeneity within individual extracellular vesicles and captures spectral features of nanostructures, such as synapses, in intact cells. Furthermore, igSRS's intrinsic optical sectioning capability allows for high-resolution, three-dimensional mapping of chemical distributions in complex systems like neurons. With high sensitivity and chemical specificity, igSRS offers transformative potential for a broad range of applications in biological and materials sciences.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"14899-14909"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144023954","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 designs of polarization-independent structures have reduced the need for polarized illumination, they are often limited by either low Q factors or low resonance modulation. Here, we design and experimentally demonstrate a metasurface with polarization-independent quasi-bound state in the continuum (quasi-BIC), where the unit cell consists of four silicon squares arranged in a two-dimensional array and the resonance properties can be controlled by adjusting the edge length difference between different squares. Our metasurface experimentally achieves a Q factor of approximately 100 and a resonance modulation of around 50%. This work addresses a common limitation in previous designs, which either achieved high Q factors exceeding 200 with a resonance modulation of less than 10%, leading to challenging signal-to-noise ratio requirements, or achieved strong resonance modulation with Q factors of only around 10, limiting light confinement and fine-tuning capabilities. In contrast, our metasurface ensures that the polarization-independent signal is sharp and distinct within the system, reducing the demands on signal-to-noise ratio and improving robustness. Experiments show the consistent performance across different polarization angles. This work contributes to the development of versatile optical devices, enhancing the potential for the practical application of BIC-based designs in areas such as optical filtering and sensing.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"15682-15689"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031160","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}

The proposed design consists of a periodic pattern printed on the top of a thin substrate and a bias network on the bottom, with varactor diodes symmetrically integrated into the top metal layer. Based on the equivalent circuit model, the mechanism of wideband tuning is analyzed theoretically. The corresponding simulation results indicate that the designed AFSS can achieve a large tuning range for the first operating band from 1.12 to 7.86 GHz while maintaining stability in the second operating band. This allows for a continuous variation from a small BR to a large BR, with a tuning range reaching 601.79%. To the best of the authors' knowledge, this is the first time that the concept of band ratio range (BRR) has been proposed to characterize the level of BR variation. Considering the feasibility of fabrication and limitations due to the tuning range of a single commercially available varactor diode, measurements were performed based on two fabricated prototypes. The simulation results are consistent with the experimental results. Compared with existing literature, the proposed AFSS can provide significant advantages such as good angular stability, polarization insensitivity, miniaturization, and ultra-wideband tunability. Our design is applicable to controlling the propagation of electromagnetic waves in various communication systems and is well-suited for electromagnetic shielding in communication devices or optical devices across different frequency bands.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"15901-15916"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144063968","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}

The SAAs are the quasi-analytical algorithm version 6 (QAA_v6) and the generalized inherent optical properties model (GIOP), while the satellite data are from the moderate resolution imaging spectroradiometer on the aqua satellite. The water body was classified following a proposed system, also separated via the trophic level (oligotrophic, mesotrophic, and eutrophic) based on chlorophyll-a concentration, so the performance of these two SAAs was evaluated for the different water types. For the water types we evaluated, both QAA_v6 and GIOP are found to have different applicable water types in retrieving absorption properties, and the relatively reliable retrieval results of absorption properties are mainly in the water types 3-13, and at the wavebands shorter than 500 nm. In addition, the retrieval performance of these two SAAs for adg (the sum of colored dissolved organic matter and non-pigmented particulate matter) and aph (phytoplankton pigment) in the eutrophic waters in the MSC still needs to be improved. Before 500 nm, MODIS-Aqua data can provide reliable anw (non-water absorption), adg, and aph with QAA_v6; and can provide reliable anw and aph with GIOP. This study provides what we believe to be a new and more detailed perspective for evaluating the retrieval of absorption properties using these two SAAs in the MSC, and our results suggest that water types should be considered in improving the estimation of intermediate variables in these SAAs.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 7","pages":"14910-14942"},"PeriodicalIF":3.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034243","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}

The phase and intensity noise properties of this extraction process are comprehensively investigated.

The simplicity and low phase noise characteristics of this approach demonstrate its capability in maintaining the coherence of a frequency comb line with ultra-narrow linewidth. Furthermore, the intensity noise of the extracted comb line is found to be strongly dependent on amplified spontaneous Brillouin scattering, further emphasizing the benefits of the all-PM design.
