This technique has unlocked new possibilities for single-shot measurements of transient phenomena in physics, photonics and biological systems. However, its applicability in ultrafast regimes is hindered by temporal aliasing, which arises when pulses are spaced closer than their stretched duration. Here we introduce temporally super-resolved time-stretch spectroscopy that overcomes this limitation. By storing a sequence of ultrashort pulses—each encoding a unique, non-repetitive spectral event—in an optical cavity and retrieving them sequentially using an asynchronous pulse picker and a dispersive Fourier transformation oscilloscope, we isolate individual pulses and suppress aliasing. This achieves a three-orders-of-magnitude improvement in temporal resolution. In proof-of-concept experiments, we resolve the spectral evolution of 25-GHz electro-optic comb pulses and distinguish spectra separated by just 3 ps. This technique enables continuous, picosecond-resolved measurements of non-repetitive spectra and is readily applicable to ultrafast spectroscopic sensing.

Here we demonstrate the generation of light springs at relativistic intensities, reaching peak values above 1.4 × 1018 W cm−2, using a scalable and high-power-compatible optical architecture. By spectrally separating a broadband high-power pulse, imprinting distinct helical phases using off-axis spiral phase mirrors, and coherently recombining the components with engineered dichroic optics, we realize controlled spatiotemporal OAM in a geometry compatible with large-scale laser facilities. Hyperspectral imaging combined with off-axis holography enables full spatiotemporal reconstruction of the focal fields, revealing tunable transverse rotation. Furthermore, controlled spectral chirp allows manipulation of the temporal evolution of the transverse mode structure. These results establish a scalable route to relativistic light fields with tailored spatiotemporal OAM and provide new opportunities for structured laser–plasma interactions.

Harnessing plasmonic hot carriers for macroscopic systems remains challenging, limiting applications in tissue-level neuromodulation and human–machine interfaces. We introduce a hot-carrier artificial leaf optoelectronic device, formed by thermally self-organized three-dimensional gold-titanium dioxide units on ultrathin membranes.

The resulting nanoplasmonic devices enable leadless, multimodal optoelectronic modulation and pixel-less optical pattern recognition, presenting a potentially scalable platform for hot-carrier-enabled biomedical and human–machine interface technologies.

Here we investigate this trade-off across a wide range of devices and identify an FF limit arising from field-dependent free-charge generation. This limit becomes more severe as voltage losses are minimized, thereby imposing an open-circuit voltage–FF trade-off. To quantitatively describe this limit, we develop an analytical model for field-dependent charge generation, revealing that the underlying cause is the field-sensitive charge-transfer process between excitons and charge-transfer states. This sensitivity originates from the field-induced charge-transfer state energy variations, mainly caused by the Stark effect. Guided by this physics-based model, we highlight that a long exciton lifetime is one of the practical and effective methods to overcome the FF limit. The fill factor of organic solar cells is limited by field-dependent charge generation due to exciton/charge-transfer coupling. Modelling coupled with a new guest–host design enables prolonged exciton lifetime, simultaneously raising the fill factor and open-circuit voltage in organic solar cells.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 9","pages":"1040-1047"},"PeriodicalIF":38.1,"publicationDate":"2026-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41566-026-01946-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148291425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Worldwide quantum key distribution (QKD) networks have been demonstrated in the field. The measurement-device-independent protocols have closed critical side channels in physical implementations and offer a trusted-node-free network structure. In particular, the twin-field (TF)-QKD can greatly extend the transmission distances with currently available technologies. Here we propose and demonstrate a photonic integrated TF-QKD network over long distances. We develop a hybrid photonic transmitter chip that integrates a self-injection locking laser featuring a high-Q silicon nitride microring resonator and a thin-film lithium niobate circuit consisting of multiple high-speed intensity and phase modulators. Furthermore, we propose a scalable quantum spine-leaf network structure, which has high capacity and flexible configuration. To prove the feasibility, we experimentally demonstrate a four-user quantum spine-leaf network based on the TF-QKD protocol and show the full connections among all users. We report the network over up to 540-km optical fibres at secret key rates higher than the repeaterless channel capacity. Furthermore, we show that our network can reliably support up to 50 users for high-quality video calls at metropolitan distances. The results show that the photonic integrated quantum spine-leaf network, benefiting from miniaturization, CMOS compatibility and long distance, paves the way for the large-scale deployment of quantum communications. A four-user quantum spine-leaf network over up to 540-km fibre is demonstrated using a twin-field quantum key distribution protocol.

Here we propose a super-Snell scanning light-field display (SSS-LiD) for high-resolution glasses-free 3D display across an ultrawide viewing angle. Inspired by Snell’s window effect, we designed a low-aberration, compact super-Snell lenticular lens array that enables a 150° viewing angle. By integrating this optics with a synchronous holistic mechanical scanning method that exploits the persistence of vision, we achieve an 8.0-fold and 3.2-fold enhancement in horizontal and vertical spatial resolution, respectively. Compared with leading commercial solutions, SSS-LiD demonstrates nearly three times the viewing angle and increases the resolution by up to 2.5 times.

Here we report a wide-temperature-range fluid-phase grain boundary (WTR-FGB) strategy enabled by incorporating a molecular complex that remains fluid between −40 °C and 85 °C. When introduced into polycrystalline perovskite films, this molecular complex is found to preferentially localize at grain boundaries, forming a dynamically adaptive and mechanically compliant intergranular network. This WTR-FGB configuration appears to accommodate thermally induced lattice mismatch, mitigate strain accumulation and suppress defect evolution during thermal cycling. Correspondingly, perovskite films exhibit enhanced structural integrity, improved photoluminescence stability and reduced morphological degradation under repeated temperature variations. These material-level changes are associated with improved device performance, enabling n–i–p perovskite solar cells with a certified power conversion efficiency of 26.52%. Thermal cycling durability is also improved, with p–i–n devices retaining over 92% of initial power conversion efficiencies after 200 cycles in accordance with the International Electrotechnical Commission 61215 standard. This work suggests that mechanically adaptive WTR-FGB engineering may offer an effective pathway towards improving the efficiency and thermal robustness of perovskite photovoltaic devices under operational temperature fluctuations.
