Recent advances in silicon nitride low-loss photonic integrated circuits allowed compact self-injection-locked semiconductor lasers to achieve exceptional coherence. Yet this architecture remains limited by sensitivity to detuning and feedback phase: narrow-linewidth operation occurs only at specific operating points, and maintaining the locked state requires active control, limiting robustness and hindering practical deployment. Here we demonstrate a photonic integrated turnkey self-injection-locked laser that eliminates these constraints, guaranteeing self-injection locking to a narrow-linewidth state at any drive current. Our approach exploits the feedback-phase dispersion, set by the spatial arrangement of resonator couplers—which governs the evolution of locking regimes across consecutive cavity modes. By engineering the feedback-phase dispersion and overlapping locking ranges in a high-Q silicon nitride photonic integrated microresonator, we constrain the laser to remain on narrow-linewidth branches during tuning, eliminating transitions into the free-running state. The photonic integrated laser exhibits persistent locking with intrinsic linewidths below 10 Hz at all drive currents, as well as during mode-hop-free 1.5-GHz frequency chirps enabled by monolithically integrated piezoelectric actuators. The architecture transforms the sensitive self-injection locking of low-loss photonic integrated circuits into a robust and scalable approach to ultralow-noise lasers. Feedback-phase dispersion in a silicon nitride photonic integrated circuit enables a self-injection-locked laser to maintain its locked state at any drive current, resulting in a robust, low-noise, narrow-linewidth integrated laser.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 10","pages":"1146-1152"},"PeriodicalIF":38.1,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41566-026-01985-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078896","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}

Here we develop lattice light sheet activation structured illumination microscopy (LA-SIM), which integrates the advantages of superior optical sectioning and low phototoxicity offered by light sheet microscopy with SR-SIM in both linear and nonlinear schemes, using reversibly photoswitchable fluorescent protein. We also implement rationalized deep-learning denoising in a self-supervised manner, enabling high-quality three-dimensional SR images at limited signal-to-noise ratios, while achieving spatial resolution improvement beyond twofold relative to the diffraction limit in both lateral and axial dimensions (up to 87 nm and 203 nm, respectively). We utilize the high-quality rationalized deep-learning LA-SIM data to train a large-scale transformer model, SRFormer-pMoE, which overcomes the inferior properties and limited palette of reversibly photoswitchable fluorescent proteins. We show that the LA-SIM system syncretized with the SRFormer-pMoE model enables multicolour volumetric SR imaging from cultured cells to multicellular embryos, shedding new light on bioprocesses by tracking subcellular dynamics at high spatiotemporal resolution for durations of hours.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"1 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087873","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}

Spatial division multiplexing (SDM) using multicore or multimode fibres is a promising solution to overcome the capacity limit of single-mode fibres. However, long-haul SDM transmission faces substantial challenges due to modal dispersion, which imposes heavy computational loads on digital signal processing for signal equalization. Here we propose parameterized SDM transmission, where programmable photonic unitary processors are installed at intermediate nodes. Instead of relying on conventional digital equalization on only the receiver side, our approach enables direct optimization of the SDM transmission channel itself by the programmable unitary processor, which reduces digital post-processing loads. We introduce a gradient-based optimization algorithm using a differentiable SDM transmission model to determine the optimal unitary transformation. Using this approach, we implement a telecom-grade programmable photonic unitary processor for low-loss, wideband (full C band), polarization-independent and high-fidelity (R2 > 96% across the C band) operation and experimentally report 1,300-km transmission using a three-mode fibre. The optimized photonic processor substantially reduces modal dispersion and post-processing complexity. Our results establish a scalable framework for integrating photonic computation into optical layers, enabling more efficient, high-capacity optical networks. A programmable photonic unitary processor for compensating modal dispersion allows long-haul (1,300 km) high-quality data transmission over a three-mode fibre.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 10","pages":"1193-1204"},"PeriodicalIF":38.1,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41566-026-01997-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149049822","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}

Here we map where photonic accelerators can matter in modern artificial intelligence infrastructure, and what must change for their impact at scale. We distinguish cloud-oriented, general-purpose photonic accelerators from application-specific, edge-oriented systems. In the cloud, the central challenge is scalability under tight energy budgets: heterogeneous systems with large vector inputs suffer from losses and electro–optic interfaces that dominate power and impede throughput, preventing the commercial deployment of photonic tensor cores. At the edge, opportunities arise wherever ultralow latency or high spatial parallelism are required and tight energy constraints dominate—for instance, in on-fibre optical processing and vision—yet progress is limited by the underwhelming scalability of all-optical nonlinearities, the lack of efficient reconfigurability, and a sizable optics footprint. We conclude that photonics is a viable near-term strategy within the existing digital ecosystem, and with focused advances along these axes, it can enable more sustainable artificial intelligence and open the door to broader adoption over the next decade. The merits of photonic accelerators for artificial intelligence applications are discussed, with an emphasis on cloud versus edge systems.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 10","pages":"1131-1138"},"PeriodicalIF":38.1,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022127","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}

Here we introduce a colloidal quantum dot (QD) interlayer as a plasmonic coupling medium in an inverted phosphorescent organic light-emitting diode architecture to mitigate these losses. Time-resolved photoluminescence measurements reveal an efficient plasmonic coupling between the emissive layer and the QD interlayer, enabling the recovery of energy that would otherwise be dissipated through surface plasmon polariton modes. Three-dimensional finite-difference time-domain simulations further demonstrate that the QD interlayer modifies the local density of optical states, redistributes the trapped optical energy and enhances outcoupling into air modes. Quantitative analysis indicates that the QD interlayer intercepts approximately 30.7% of the energy initially coupled to surface plasmon polariton modes. Consequently, the QD-integrated inverted phosphorescent organic light-emitting diode achieves an external quantum efficiency of 20.95%, representing a 1.3-fold improvement over the reference device (15.67%). These findings establish QD interlayers as an effective and versatile strategy for suppressing plasmonic losses and improving light extraction in high-performance OLEDs.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"81 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010600","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}
