Notably, we observe a novel phenomenon of wavelength-dependent periodic fluctuations in anisotropic AO scattering with different in-plane orientations. This effect is attributed to inter-polarization scattering involving the fundamental modes combined with intramodal AO interaction within the TFLN waveguide. Therefore, the trade-off between efficiency and fluctuation must be carefully considered. When the acoustic excitation direction is 150° (relative to the −Y-axis of LN), the Rayleigh acoustic mode R0 achieves a maximum intramodal scattering efficiency of −20.9 dB at 2.496 GHz, which corresponds to a VπL of 2.34 V·cm. Additionally, the higher-order acoustic mode at 3.544 GHz demonstrates a moderate conversion efficiency of −26.7 dB under a 75° emission angle, with a minimal wavelength-dependent fluctuation of 1.1 dB during AO modulation operation over a bandwidth exceeding 82 nm. By carefully selecting specific orientations or wavelengths, it is possible to tailor diverse applications for anisotropic TFLN AO devices, such as highly flattened AO modulation, enhanced intramodal AO interaction, and efficient inter-polarization conversion. These findings pave the way for developing integrated photonic–phononic interaction devices on widely utilized anisotropic material platforms.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"51 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144329425","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}

Nonetheless, similar to their biological counterparts, these devices face a critical limitation: their scotopic-adaptive photoresponse struggles to comprehensively encompass the visible spectrum, impeding color differentiation under weak illumination. In this study, we present a bionic memory phototransistor (MPT) based on ternary CdSxSe1–x nanoribbons, which integrate the scotopic sensitivity of rods with the chromatic acuity of cones to enable RGB color discernment in weak-light conditions. The CdSxSe1–x nanoribbons synthesized in a selenium-rich atmosphere exhibit fewer chalcogen vacancies and a progressively reduced photoelectric storage window, confirming the pivotal role of these vacancies as surface oxygen adsorption sites forming a storage medium. By leveraging the charge storage accumulation effect and energy band engineering, we achieve weak light detection across the broad visible range of 300–725 nm, with a specific detectivity surpassing 1017 Jones. Through the synergistic operation of CdS0.30Se0.70, CdS0.58Se0.42, and CdS MPTs with tailored spectral properties, we accomplish detection and discrimination of weak RGB light at 200 nW·cm–2 under scotopic-adaptive modes. This integration of rod-inspired scotopic adaptation with cone-like chromatic discrimination offers an innovative design concept for the development of next-generation visual perception technologies.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"22 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319539","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}

Multicolor fluorescence microscopy can promote the analysis of complex biological structures, optimize medical diagnosis and precise treatment, and reveal the mechanism of chemical reactions and the composition of materials. However, the imaging speed of multicolor SIM is relatively limited, and its spatial resolution improvement remains constrained. In this study, we developed a fast multicolor fluorescence super-resolution microscopic imaging technique that leverages the benefits of snapshot multicolor wide-field super-resolution ghost imaging via sparsity constraints, while further improving the spatial resolution through structured illumination. Its theoretical framework was established based on the intensity correlation theory. The experimental results demonstrated a 2.65-fold spatial resolution enhancement beyond the diffraction limit and a 3-fold temporal resolution improvement over traditional three-color SIM imaging.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"231 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311718","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}

The only few published experiments in this field are essentially dedicated to identifying the signature of circular dichroism. On the basis of conventional methods employed in the polarimetric study of macroscopic samples, we propose an alternative experimental technique which allows a complete determination of the relevant optical anisotropy parameters of a single nano-object (circular and linear dichroisms and birefringences). The retrieval of weak signals from bright-field extinction measurements is made possible by the original combination of polarization and spatial modulation spectroscopies. The framework and applicability of the method and data processing are discussed in detail. They are illustrated through the study of two different types of nanoparticles: achiral homodimers of gold nanospheres and chiral gold nanostructures lithographied on a transparent substrate.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"43 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311720","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}
