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}

Here we report a coordination-regulated strategy based on chemical bath deposition that resolves this bottleneck by governing the NiOx crystallization kinetics. By leveraging the high thermodynamic stability of Ni2+–potassium tartrate (Pta) complexes, we suppress disorderly aggregation and halve the hydrolysis rate constant to 0.124 l mol−1 min−1. This precise kinetic control yields dense and conformal films with refined 4.8-nm nanocrystallites. This nanostructural refinement maximizes the surface density of hydroxyl groups, providing robust anchoring sites where self-assembled monolayers can form a chemically cohesive and defect-suppressed buried interface. Our Pta-NiOx strategy delivers inverted devices with a champion power conversion efficiency of 27.40% (certified reverse-scan power conversion efficiency of 27.35%) and module efficiencies of 23.42% (17.7 cm2) and 21.97% (81.5 cm2). Small-area devices retained 90% of their initial power conversion efficiency after 2,656 h, and 17.7 cm2 mini-modules retained over 90% after 1,200 h under the ISOS-L-1I protocol.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"15 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010458","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}

Such space–time structured light fields—ranging from localized wave packets to spatiotemporal vortices—hold promise for transforming ultrafast science, laser machining, imaging and optical communications. However, their realization has so far relied on complex free-space configurations, requiring bulky components such as gratings and spatial light modulators placed in Fourier-conjugate planes. Here we introduce a chip-scale platform that generates space–time wave packets directly from a laser array, bridging the gap between structured light physics and integrated photonics. Our design uses distributed feedback lasers with dual-ended geometries that produce mutually coherent sub-beams with stable phase contrasts. This versatile architecture enables precise control of spatial–spectral correlations, allowing the synthesis of incoherent or coherent space–time wave packets with scalable width and propagation length. By uniting field structuring and lasing within a single device, this approach opens a pathway towards integrated light sources capable of on-chip beam shaping, combining and spatiotemporal control, with far-reaching implications in microscopy, tomography, communications and ultrafast optical technologies. An integrated semiconductor laser array can directly generate incoherent space–time wave packets with propagation-invariant and self-healing characteristics.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 10","pages":"1174-1181"},"PeriodicalIF":38.1,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148933250","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}
