However, current methods often struggle to analyse heterogeneous and spatially varying chiral samples. On one hand, spectroscopic approaches, although sensitive, often require large sample volumes and produce ensemble-averaged data. On the other hand, chiral imaging delivers spatial resolution at the expense of time-consuming confocal scanning and complex instrumentation. Addressing this gap, we introduce a platform for wide-field, spectrally resolved optical activity imaging. Using polarization-sensitive off-axis holography to simultaneously capture left- and right-circularly polarized components, our system allows the single-shot retrieval of circular dichroism and optical rotatory dispersion images, as well as eliminating artefacts caused by linear anisotropies. Our results are not only consistent with traditional circular dichroism spectroscopy but also demonstrate the ability to spatially resolve local chirality variations lost by ensemble averaging, including enantiomeric excess. This platform holds great promise for analysing complex biological and material samples, expanding the scope of chiral characterization.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"26 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715275","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}

To create an immersive and accessible experience, the display engine of the MR display must project perceptually realistic 3D images over a wide field of view observable from a large range of possible pupil positions, that is, it must support a large étendue. Current MR displays, however, fall short in delivering these capabilities in a compact device form factor. Here we present an ultra-thin MR display design that overcomes these challenges using a unique combination of waveguide holography and artificial intelligence (AI)-driven holography algorithms. One of the key innovations of our display system is a compact, custom-designed waveguide for holographic near-eye displays that supports a large effective étendue. This is co-designed with an AI-based algorithmic framework combining an implicit large-étendue waveguide model, an efficient wave propagation model for partially coherent mutual intensity and a computer-generated holography framework. Together, our unique co-design of a waveguide holography system and AI-driven holographic algorithms represents an important advancement in creating visually comfortable and perceptually realistic 3D MR experiences in a compact wearable device.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"63 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715276","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}

For example, it is challenging to achieve uniform deposition and prevent aggregation of small-molecule materials during solution processing, negatively impacting cell efficiency, reproducibility and stability. Here we co-deposit a new p-type small molecule (D4PA) with the perovskite film. The intramolecular C–C coupling in D4PA enables strong multi-anchoring interactions with both the perovskite and substrate, enhancing interfacial charge transport and inhibiting defect formation within the perovskite layer. The C–C coupling also introduces steric hindrance, creating twisted molecular conformations that effectively prevent molecular aggregation, extend the solution processability and increase device reproducibility. Our devices exhibit a certified power conversion efficiency of 26.72% and a certified maximum power point tracking efficiency of 26.14% in small-area devices. A power conversion efficiency of 23.37% and a certified maximum power point tracking efficiency of 22.66% are achieved in a mini-module with an effective area of 10.86 cm2. The devices maintain over 97.2% of their initial efficiency after 2,500 h of continuous operation at their maximum power point.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"37 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669620","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}
