However, direct real-time observations of EWP evolution and full reconstructions of the quantum properties of EWPs, including both amplitude and phase, are lacking. Here we introduce and demonstrate a comprehensive approach for the direct measurement and complete characterization of structured EWPs created within a prototypical Fano resonance. Because of its analogy with frequency-resolved optical gating (FROG), we named the method photoelectron FROG. The correlated EWP is initiated by a carefully engineered extreme UV pump pulse. A weak near-infrared laser field, serving as a probe pulse, samples the evolution of the EWPs in the time domain, as well as in the frequency domain. The amplitude and phase of the EWPs are obtained via a time-dependent reconstruction algorithm based on a short-time Fourier transformation. Given the excellent agreement between our experimental results and time-dependent reconstructions, we expect this method to be broadly applicable to the study of ultrafast processes, especially electronic ones, in complex systems, as well as the coherent control of such systems on their fundamental timescales.

However, the requirement of using external light sources involves bulky equipment that hinders point-of-care applications. Here we introduce a plasmonic sensor with an embedded source of light provided by quantum tunnel junctions. An optically resonant, doubly periodic nanowire metasurface serves as a top contact for the junction and provides extremely uniform emission over large areas, amplified by plasmonic nanoantenna modes that simultaneously enhance the spectral and refractive index sensitivity. As a proof of concept, we demonstrate spatially resolved refractometric sensing of nanometre-thick polymer and biomolecule coatings. Our results open exciting prospects based on a disruptive platform for integrated electro-optical biosensors.

Ultraintense lasers represent the pinnacle of this control, concentrating light to extreme intensities at which electrons oscillate at relativistic velocities within a single optical cycle. These extraordinary conditions offer unique opportunities to probe the fundamental aspects of light–matter interactions and develop transformative applications. However, the precise characterization of intense, ultrashort lasers has lagged behind our ability to generate them, creating a bottleneck in advancing laser science and its applications. Here we present the first single-shot vector field measurement technique for intense, ultrashort laser pulses that provides an unprecedented insight into their complete spatiotemporal and polarization structure, including quantified uncertainties. Our method efficiently encodes the full vector field onto a two-dimensional detector by leveraging the inherent properties of these laser pulses, allowing for real-time characterization. We demonstrate its capabilities on systems ranging from high-repetition-rate oscillators to petawatt-class lasers, revealing subtle spatiotemporal couplings and polarization effects. This advancement bridges the gap between theory and experiment in laser physics, providing crucial data for simulations and accelerating the development of novel applications in high-field physics, laser–matter interactions, future energy solutions and beyond.

Furthermore, perovskite nucleation and growth are highly sensitive to processing methods, increasing the complexity of large-scale production. To address these challenges, we establish a temperature-controlled vacuum quenching method combined with in situ photoluminescence spectrometry to fabricate perovskite films under monitoring. We systematically study the commonly used quenching nucleation processes and reveal the impact of the pumping speed, solvent system and additives on the vacuum quenching process. We manage to modulate the perovskite nucleation process by lowering the temperature during the vacuum quenching process, thereby broadening the time window for post-processing treatments to obtain high-quality large-area perovskite films. The resultant 1.55 eV mini-module achieves a PCE of 22.69% with an aperture area of 11.7 cm2 (and a certified aperture-area PCE of 21.60%), whereas the corresponding PSC maintained >93% of its initial efficiency after continuously operating at 45 °C for 3,500 h under 1 sun illumination. This approach enables high-quality, uniform and large-area perovskite films on rigid, flexible and curved substrates, demonstrating the feasibility of our strategy for improving the scalability of renewable PSC technology. A temperature-controlled vacuum quenching method enables the fabrication of perovskite solar modules with a power conversion efficiency of 22.69% and an area of 11.7 cm2, while the corresponding cells maintain over 93% of their initial efficiency after 3,500 h of operation.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"19 9","pages":"968-976"},"PeriodicalIF":32.9,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479028","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}
