1. Integrated optical isolators for broadband multi-laser operation.
1. 用于宽带多激光器工作的集成光隔离器PMID:日期:2026-08-13Photonic integrated circuits commonly feature visible or near-infrared lasers that are vulnerable to destabilizing back-reflections and must be protected by isolators-non-reciprocal optical components enforcing one-way light propagation. Despite recent progress, high-performance isolators remain bulky off-chip components, while on-chip implementations suffer from challenging fabrication, high optical absorption or narrow optical bandwidth. Here we propose and experimentally demonstrate a magnet-free, intrinsically broadband travelling-wave isolator built from foundry-compatible components. Using radio-frequency electro-optic modulation to create synthetic motion across four parallel waveguides, we realize dynamic rotating destructive interference that continuously cancels backward-propagating light while leaving forward-propagating light unaffected. We reach ~30 dB peak isolation, maintain >24 dB isolation across a 30-nm-wavelength span with thermo-optic adjustment and show >20 dB isolation for two lasers simultaneously within 10 nm without any adjustment. The demonstration's 770-800-nm-wavelength span covers key alkali atomic transitions, enabling on-chip laser isolation for atomic spectroscopy, laser cooling and locking applications. Our isolator approach, applicable from the visible to telecom wavelength spectrum, offers a compelling practical solution, opening the way for fully integrated atomic clocks, quantum sensors, advanced telecommunications and tunable laser systems on a single chip.

2. Correlated electrons extend X-ray high-harmonic generation beyond the single-electron limit.
PMID:日期:2026-08-07High-harmonic generation underpins attosecond science. For over three decades, high-harmonic upconversion has been framed within the confines of a single-active-electron light-matter interaction featuring a well-defined cutoff photon energy. Here we demonstrate experimentally that correlated electrons can propel high-harmonic emission beyond this single-active-electron limit, markedly increasing the generated photon energies. We observe a weak secondary plateau that extends the conventional cutoff beyond 120 eV up to the water window at 280 eV. This phenomenon arises from double-electron recombination of strongly correlated electron pairs, resulting in a new cutoff scaling of up to 5.5 times the ponderomotive energy of the rescattering electrons, which notably deviates from the conventional scaling factor of 3.2. These findings reshape our fundamental understanding of the high-harmonic upconversion process and position high-harmonic generation as a potent photonic probe of attosecond-to-femtosecond electron correlations in quantum systems, opening new pathways for advanced ultrafast spectroscopy, novel attosecond source development and the exploration of strongly correlated quantum materials.

3. Large-scale compressive microscopy via diffractive multiplexing across a sensor array.
3. 通过传感器阵列上的衍射复用实现的大规模压缩显微术PMID:日期:2026-07-28Microscopes face a trade-off between spatial resolution, field of view and frame rate-improving one of these properties typically requires sacrificing others, owing to the limited spatiotemporal throughput of the sensor. To overcome this, we propose a new microscope that achieves snapshot gigapixel-scale imaging with a sensor array and a diffractive optical element. We improve spatiotemporal throughput in two ways. First, we capture data with an array of 48 sensors, resulting in 48× more pixels than a single sensor. Second, we use point spread function engineering and compressive sensing algorithms to fill in the missing information from the gaps between the individual sensors in the array, further increasing the spatiotemporal throughput of the system by an additional >5.4×. The array of sensors is modelled as a single large-format 'super sensor', with erasures corresponding to the gap areas between sensors. The sensor array is placed at the output of a (nearly) 4 imaging system, with a diffractive optical element in the Fourier plane that generates a distributed multi-spot point spread function. This enables encoding of information from the entire super-sensor area, including the gaps. We then perform a large-scale regularized reconstruction using a direct fully shift-variant convolutional forward model, assuming that the object is sparse in some domain. Our microscope can achieve ~3 μm resolution over >5.2 cm field of view at up to 120 fps, culminating in an effective total spatiotemporal throughput of 25.2 billion pixels per second. We demonstrate the versatility of our microscope in two different modes: structural imaging via dark-field contrast and functional fluorescence imaging of calcium dynamics across dozens of freely moving .

4. Beyond quantum linear optics with adaptive boson sampling.
4. 超越具有自适应玻色采样的量子线性光学PMID:日期:2026-07-20[中文摘要] 通用光子量子计算需要光学非线性，这可以通过中间测量和自适应性来提供，以补充线性光学元件。在近期展望中，探究是否能在有限资源下获得超越线性光学的动力学至关重要。尽管近期结果显示了线性光学动力学如何对可生成的光子态集合施加限制，但用于研究非线性动力学涌现的定量方法在很大程度上仍然缺失。在此，我们分析了一种可以超越此类限制的情形。我们通过利用一种自适应玻色采样架构来实现这一点，其中光子器件中实现的光学演化通过基于测量的反馈逐步自适应。我们引入了实用方法来量化相对于线性光学出现差距的程度，并从线性光学演化的性质中推导出非线性见证量。然后，我们在最先进的光子平台上实现了复杂度递增的自适应玻色采样架构，验证了所开发的工具箱，既通过实现实时自适应性，也通过后选择对更复杂配置的自适应协议进行模拟。特别地，我们通过实验探测了一种情形，其中可以出现线性光学范式内无法获得的非线性动力学，从而展示了具有有限自适应性的光学架构是探索新情形的强大测试平台。
[英文摘要] Universal photon-based quantum computing requires optical nonlinearities, which can be induced by intermediate measurements and by adaptivity, to be supplied to linear-optical elements. In a near-term perspective, it is essential to probe whether dynamics going beyond linear optics can be accessed with a limited amount of resources. Although recent results show how linear-optical dynamics implies bounds on the set of photonic states that can be generated, quantitative methods for studying the emergence of nonlinear dynamics are largely missing. Here we analyse a regime in which such bounds can be surpassed. We do this by leveraging an adaptive boson sampling architecture in which the optical evolution implemented in a photonic device is progressively adapted via measurement-based feedback. We introduce practical methods to quantify the emergence of a gap with respect to linear optics and derive nonlinearity witnesses from the properties of linear-optical evolution. Then, we validate the toolbox developed within adaptive boson sampling architectures of increasing complexity implemented on a state-of-the-art photonic platform, both by realizing real-time adaptivity and by emulating adaptive protocols via post-selection for more complex configurations. In particular, we probe experimentally a regime in which nonlinear dynamics, unobtainable within a linear-optical paradigm, can arise, thus showing how optical architectures with limited adaptivity are a powerful testbed for exploring new regimes.

5. Tracking electrons at the space-time limit.
5. 在时空极限下追踪电子PMID:日期:2026-07-03[中文摘要] 电子波函数的动力学特性往往对其空间分布产生非平凡的影响，例如在隧穿过程或化学键形成过程中。然而，要揭示时空耦合，需要在本征的电子波函数尺度上，即在所谓的时空极限下，进行超快视频成像。本文利用具有阿秒时间分辨率的原子尺度光波驱动扫描隧道显微镜，在电子隧穿能量势垒的过程中，实验上实现了对单个电子在时空极限下本征量子运动的观测。通过两束时间延迟的近红外脉冲形成相位控制的单周期波形来调制隧穿势垒，识别出短于1飞秒的孤立电子隧穿瞬态过程。测量得到的空间延展取决于多光子动力学与场驱动动力学之间的相互作用，这一点已通过完整的量子模拟得到证实。我们实验上将阿秒受限的隧穿波包局域化到埃尺度，并利用其绘制了银表面上单个铜吸附原子的图像。这种将阿秒科学与原子尺度扫描隧道显微镜相融合的方法，使得研究原子、分子和固体内部的波函数动力学成为可能。
[英文摘要] The dynamics of an electronic wavefunction often have non-trivial consequences on its spatial distribution, for example, during tunnelling or chemical bond formation. Yet, revealing spatio-temporal coupling requires ultrafast videography at the intrinsic size of electronic wavefunctions, at the so-called space-time limit. Here we experimentally access the intrinsic quantum motion of individual electrons at the space-time limit while they are tunnelling through an energy barrier, using atomic-scale lightwave-driven scanning tunnelling microscopy with attosecond time resolution. While modulating the tunnelling barrier with two time-delayed near-infrared pulses forming phase-controlled single-cycle waveforms, isolated electron tunnelling transients shorter than 1 fs are identified. The measured spatial extension depends on the interplay of multi-photon and field-driven dynamics, as confirmed by full quantum simulations. We experimentally localize the attosecond-confined tunnelling wave packet on the angstrom scale and use it to map a single copper adatom on a silver surface. This fusion of attosecond science with atomic-scale scanning tunnelling microscopy makes it possible to study wavefunction dynamics inside atoms, molecules and solids.

6. Self-Organized Nanoplasmonic Artificial Leaf for Hot-Carrier Bioelectronic Interfaces.
6. 自组织纳米等离激元人工叶子用于热载流子生物电子接口PMID:日期:2026-06-24Without discrete pixels or wired leads, natural plant leaves respond to light and relay electrochemical signals to surrounding tissues through nanoscale chlorophyll-containing protein complexes - an elegant capability sought in next-generation leadless optoelectronic systems. Although semiconductors and their heterojunctions are commonly employed to mimic photosynthesis, nanoplasmonic structures offer a largely untapped alternative. 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 3D gold-titanium dioxide units on ultrathin membranes. These nanoplasmonic interfaces enhance visible-light optoelectronic responsiveness at sub-100-nm thickness, support highly localized hot-carrier injection, and exhibit stable, linear performance over a wide range of light intensities, overcoming the material, bandgap, and carrier diffusion limits of conventional semiconductors. 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, nanophotonic, and human-machine interface technologies.

7. High-speed non-volatile barium titanate field-programmable photonic gate array.
7. 高速非易失性钛酸钡现场可编程光子门阵列PMID:日期:2026-06-04Programmable integrated photonics aims to replicate the versatility of field-programmable gate arrays in the optical domain. However, scaling these systems has been prevented by the high power consumption and thermal crosstalk of conventional volatile phase shifters. Here we introduce a non-volatile field-programmable photonic gate array, implemented on a hybrid silicon-barium titanate platform, which overcomes the power scaling limitations of previous technologies. Unlike traditional thermo-optic devices that require constant power to maintain a state, our device utilizes ferroelectric domain switching to provide non-volatile memory, allowing optical circuits to be programmed and retained without any holding power or electrical bias. The hexagonal waveguide mesh integrates 58 programmable unit cells and 116 actuators, achieving nanosecond-scale switching speeds of 80 ns while reducing static power consumption to negligible levels (560 nW per π phase shift). To validate this platform, we configured the mesh to perform diverse signal processing functions, including tunable filtering, 4 × 4 linear unitary transformations and optical routing. This work establishes non-volatile ferroelectric silicon photonics as a scalable, heat-free platform essential for the next generation of energy-efficient photonic computing.

8. Isotropic shrinkage of patterned vacancies enables three-dimensional nanoprecise metastructures for visible light applications.
8. 图案化空位的各向同性收缩为可见光应用实现了三维纳米精度超结构PMID:日期:2026-05-12Three-dimensional metastructures with nanoscale feature sizes exhibit unique properties compared with structures with larger feature sizes, but are difficult to fabricate. Here we introduce implosion carving (ImpCarv), a method for photopatterning vacancies of complex geometry throughout materials, followed by isotropic shrinkage (>10-fold). ImpCarv works by photoactivating sensitizers to generate reactive oxygen species that cleave a swollen hydrogel at defined points, followed by controlled shrinkage via dehydration. ImpCarv creates three-dimensional metastructures where the refractive index of each point throughout a material can be specified with nanoscale precision via material presence or absence. By leveraging refractive index programmability for precise phase control, we demonstrate an all-optical machine learning device with nanoscale neuron sizes operating at visible wavelengths. ImpCarv may thus support diverse applications in nanophotonics and nanotechnology.

9. Strong ultrafast nonlinear optical response from megaelectronvolt electrons in semiconductors.
9. 半导体中兆电子伏特电子的强超快非线性光学响应PMID:日期:2026-04-20Understanding radiation-matter interactions on ultrafast timescales is essential for radiation detection technologies, particularly those requiring precise timing, such as plasma monitoring, synchrotron diagnostics and medical imaging. However, the detection of highly ionizing radiation is challenging due to the stochastic nature of the interactions, resulting in dispersed energy deposition. Here we show a nonlinear optical response in semiconductors induced by 150-fs, 4.2-MeV electrons that generate highly localized charge carriers. The induced sub-10-ps optical modulation reached up to 24.5%, accompanied by a blueshift in the absorption edge consistent with band filling and carrier densities of 10cm. These carrier densities are 100-fold higher than expected from the deposited energy, indicating the extreme spatial localization of carriers at inelastic collisions along the ionization trajectories, thereby leading to the observed modulation. The strong nonlinearity of the MeV-electron-induced optical response enables the precise spatiotemporal detection of ionizing radiation at room temperature using common semiconductors and laser systems.

10. Optical convolutional spectrometer.
10. 光学卷积光谱仪PMID:日期:2026-04-15Optical spectrometers are fundamental across numerous disciplines. However, miniaturized versions, while essential for in situ measurements, are often restricted to coarse identification of signature peaks and are inadequate for metrological purposes. Here we introduce a new class of spectrometer, which uses the convolution theorem as its unique mathematical foundation. Our 'convolutional spectrometer' offers unmatched performance for miniaturized systems and distinct structural and computational simplicity, featuring a centimetre-scale footprint for the fully packaged unit, low cost (~US$10) and a 2,400 cm (approximately 500 nm) bandwidth in the near-infrared region. We achieve excellent precision in resolving complex spectra with subsecond sampling and processing time, demonstrating wide near-infrared spectroscopic applications from industrial and agricultural analysis to healthcare monitoring. Specifically, our spectrometer system classifies diverse solid samples, including plastics, pharmaceuticals, coffee, flour and tea, with 100% success rate, and quantifies concentrations of aqueous and organic solutions with detection accuracy surpassing commercial benchtop spectrometers. We also realize the non-invasive sensing of human biomarkers, such as skin moisture (mean absolute error = 2.49%), blood alcohol (1.70 mg dl), blood lactate (0.81 mmol l) and blood glucose (0.36 mmol l), highlighting the potential of this new class of spectrometers for low-cost, high-precision, portable and/or wearable spectral metrology.
