These attributes have enabled breakthroughs in precision metrology, quantum optics and coherent communications. However, bringing the proven advantages of diode-pumped solid-state gain media such as neodymium-doped yttrium aluminium garnet (Nd:YAG) onto an integrated photonic platform has remained difficult, largely due to inefficient pump utilization and limited power scaling in chip-scale implementations. Here we demonstrate a photonic-integrated Nd:YAG laser–amplifier system that overcomes these challenges with a microchip-based master-oscillator–power-amplifier architecture. The seed laser, employing a double-resonant microring resonator, could reach a threshold as low as 2.9 μW. The single-pass waveguide amplifier, when optimized separately, provides up to 46.6 dB small-signal gain. Combining the low-threshold seed with cascaded waveguide amplifiers, the integrated microchip-based master-oscillator–power-amplifier delivers more than 12 dBm of amplified continuous-wave output power. These results establish Nd:YAG waveguide integration as a practical route to compact and high-performance solid-state light sources.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"11 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087872","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}

Because tunnelling also enables atomic-scale spatial resolution in scanning tunnelling microscopy (STM), integrating STM with light pulses has long been a key objective in ultrafast microscopy, spanning the picosecond and femtosecond domains, with first signatures of attosecond dynamics. However, while sub-cycle dynamics on the attosecond timescale are routinely controlled and determined with high precision, controlling the direction of attosecond currents and determining their duration have remained elusive in STM. Here we induce STM tunnelling currents using two-colour laser pulses and dynamically control their direction, relying solely on the sub-cycle waveform of the pulses. Projecting our measurement data onto one-electron and many-body theory descriptions reveals a three-step transport process in the non-adiabatic tunnelling regime as the physical mechanism, with a theory-derived current burst duration of 860 as. Despite working under ambient conditions but free of thermal artefacts, we achieve sub-angström topographic sensitivity and a lateral spatial resolution of 2 nm. This unprecedented capability to directionally control attosecond bursts will enable the triggering and imaging of ultrafast charge dynamics at the spatiotemporal microscopy frontier of lightwave electronics.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"166 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087870","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}

Conventional interface engineering uses planar interlayers to passivate and interlock the perovskite and the charge-transport layer, which often involves a trade-off between efficient charge transport and high stability. In this work, we use trans-interface engineering to create vertically aligned, mechanically tough nanolinks that penetrate both the perovskite and the charge-transport layer, simultaneously enhancing interface reliability and charge transfer. Here, as a proof of concept, we pre-incorporated triple and single organic linkers into the perovskite and the charge-transport layer, respectively, and then applied azobisisobutyronitrile-derived cyanoisopropyl radicals to trigger polymerization of the two linkers within their respective layers and to vertically bond them at the heterointerfacial contacts. A perovskite/charge-transport-layer interface enhanced by trans-interface engineering shows superior mechanical reliability compared with other reported interfacial approaches. The resultant perovskite solar cells deliver improved power conversion efficiencies of up to 27.04% (certified at 26.67%). Under maximum-power-point tracking at one-sun-intensity illumination, 92% of the tested perovskite solar cells reached T80 lifetimes of 1,400 h, demonstrating improved stability and reproducibility. This high reliability stems largely from the trans-interface engineering-induced suppression of mechanical failure in device operation. This work points to a new direction for improving perovskite solar cells using trans-interfacial materials, which is also applicable to other multilayered optoelectronic devices beyond photovoltaics.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087871","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}

In contrast, optical data storage systems face difficulties in achieving similar multilevel recording due to the limited dynamic range of photo-responsive materials and inherent signal-to-noise challenges. These material-level constraints limit optical encoding fidelity, preventing traditional optical platforms from achieving the rapid capacity growth seen in electronic storage. Here, to address these challenges, we present an approach utilizing giant anti-Stokes phonon-assisted upconversion photoluminescence via in situ laser writing and reading of upconversion carbonized polymer dots. This method enables high-capacity three-dimensional optical data storage with exceptional efficiency. Unlike conventional Stokes photoluminescence media, our approach maximizes near-infrared light utilization, achieving high resolution with ultralow noise. Our experimental demonstration showcases three-dimensional multilayer encoding with 1,024 distinct greyscale levels, reaching an estimated storage capacity of approximately 400 Tb on a DVD-sized disk while maintaining >99.99% reliability. Additionally, our methodology introduces a scalable pathway for extending greyscale encoding beyond 10,000 levels through optimized phonon–photon coupling, surpassing current petabit-scale optical storage capabilities and potentially laying the foundation for next-generation archival storage solutions with unprecedented density and fidelity.
