FHPM acquires low-frequency quantitative phase information, which is inherently limited by the numerical aperture (NA) of the objective lens based on off-axis digital holographic microscopy. This accurate but noisy initial object information, which fills the central aperture in the Fourier space, is subsequently refined by Fourier ptychographic microscopy (FPM) based on intensity-only measurements under tilted illuminations. Meanwhile, the signal-to-noise ratio and imaging resolution (frequency bandwidth) can be significantly improved simultaneously. FHPM achieves efficient synthetic-aperture QPI (9 image acquisitions to near incoherent diffraction limit), compensates the imaging aberrations, and overcomes the stringent matched-illumination requirement inherent to FPM. To the best of our knowledge, this is the first integration of interferometric and non-interferometric phase measurements into a single system, harnessing their complementary strengths. Experimental results on a USAF target and biological cells demonstrate that FHPM achieves accurate, speckle-free QPI while improving the half-pitch imaging resolution from 615 nm to 274 nm (effective NA of ∼0.98) using a 20×, 0.5NA objective lens, rendering it a promising tool for biomedical research.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"17 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853668","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}

Optical edge enhancement can extract structural and morphological information about an object; however, existing systems require bulky and complex optical configurations. Development of a low-cost, lightweight, integrable, and high-performance imaging system is thus necessary for biomedical and industrial applications in the field and onsite. Here we propose and demonstrate a compact metasurface imaging system composed of cascaded metasurfaces that function as a metalens and q-plate for isotropic edge enhancement of amplitude objects, phase objects, and biological specimens. Furthermore, we utilize the polarization degree of freedom of light in addition to amplitude and phase to achieve anisotropic edge enhancement. By utilizing different polarization states of incident light, the impulse response of the metasurface imaging system is modified to achieve real-time isotropic and directional edge enhancement while maintaining a field of view. The proposed approach demonstrates a robust, ultracompact, lightweight, efficient, and integrable platform for reliable, stable, and cost-effective point of care devices, process control, and monitoring.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"219 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853667","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}

Recently, photonic bound states in the continuum (BICs), which inherently exhibit spin and chiral nature, have drawn substantial interest owing to their ultrahigh quality factor and exceptional light confinement. However, achieving spin–orbit-locking chiral BICs or quasi-BICs remains a challenge, limiting their broader application in advanced optical devices. Here, we propose an approach to simultaneously realize spin–orbit-locking chiral BICs and quasi-BICs in magneto-optical photonic crystal slabs. When the period tripling, in-plane symmetry breaking, and time-reversal symmetry breaking operations are applied on a general and widely used honeycomb lattice, the Brillouin zone folding enabled degenerate bulk modes are transformed into a pair of BICs and a pair of quasi-BICs. The chirality of each mode is thoroughly investigated by inspecting the phase profile of the out-of-plane electric field, the radiation profile of the in-plane magnetic field, and the multipolar decomposition of near fields, all of which confirm the spin–orbit-locking feature. Our work introduces a design framework for creating chiral BICs and quasi-BICs, offering significant potential for future developments in chiral photonics and advanced optical engineering.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"263 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841668","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}

This process entails the spontaneous accumulation of population in the polariton ground state and relies on efficient energy relaxation. In this class of materials, this relaxation is mediated by exciton reservoir emission, which pumps polariton states through radiative pumping. To achieve strong light–matter coupling and sustain a high polariton density, the material must possess excitations with large oscillator strength and high exciton binding energy. While 2D perovskites exhibit these desirable characteristics, there are no reports of room-temperature polariton condensation and only one successful demonstration at cryogenic temperatures. In this work, we systematically explore the role of energy alignment between the exciton reservoir emission and the lower polariton branch in populating the polariton ground state via radiative pumping. Through cavity detuning, we shift the lower polariton energy minimum to overlap with the emission of the exciton reservoir at different energies. We identify that the multiple radiative pathways of 2D perovskites lead to inefficient radiative pumping of the lower polariton branch at the lowest-energy state, ultimately posing challenges for polariton condensation in this class of materials.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"35 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841667","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}

However, its utility is restricted by measurement biases and low throughput, making it challenging to capture temporal dynamics of intracellular diffusivity. Here we report a high-throughput single-molecule diffusivity microscopy approach (Hi-SMdM) that rapidly and unbiasedly maps nanoscale heterogeneities in molecular motion inside mammalian cells, enabling time-resolved imaging of local diffusivity dynamics. Hi-SMdM employs a self-supervised deep-learning denoising framework with a general noise model to effectively restore the scarce signals of fast-moving single molecules, while eliminating artifact motions without relying on spatial redundancies or temporal correlations. It then provides unbiased estimations of the nanoscale diffusion coefficient and improves both throughput and temporal resolution by up to an order of magnitude. We demonstrate the versatility of Hi-SMdM through time-resolved mapping of the spatially heterogeneous diffusivity of free proteins in the cytoplasm. Hi-SMdM also unveils the temporal dynamics of intracellular diffusion under hypotonic conditions in live cells. Additionally, Hi-SMdM tracks the spatiotemporal dynamics of intraorganellar diffusivity during rapid rearrangements of the ER network and functional activities of mitochondria. Overall, Hi-SMdM provides exceptional opportunities for high-throughput and unbiased single-molecule diffusivity mapping with excellent spatiotemporal resolution.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"6 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841671","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}

However, PSHE-based optical spatial differential imaging methods impose strict requirements on the polarization of the input field, limiting their application in scenarios where the polarization state of the light cannot be easily controlled or the input field is inherently a polarization field. Here, we propose an optical differentiator utilizing cascaded PSHEs to achieve full-dimensional optical spatial differential imaging. By creating giant and tiny PSHEs using liquid-crystal half-wave and quarter-wave polarization gratings, the input field is separated into two circular polarization basis vectors for independent differentiation operations. We demonstrate that this differentiator enables differential imaging of amplitude, phase, and polarization fields. Furthermore, we achieve controllable contrast in the differential images of the two circular polarization basis vectors by longitudinally or transversely moving the half-wave or quarter-wave polarization grating. Our findings might open up new possibilities for applications in areas such as advanced imaging techniques, material characterization, and optical information processing.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"30 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841672","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}
