1. Transmission of multi-level time-bin encoded cluster states over 29 km of partially deployed optical fiber.
1. 在部分部署的29公里光纤上传输多级时间bin编码的簇态PMID:日期:2026-10-01The next generation of telecommunication networks will rely on the distribution of complex quantum resources to enable secure and transformative information processing, utilizing entanglement and superposition. Cluster states-multi-qubit entangled states that retain entanglement under local measurements-are the central resource for measurement-based quantum information processing and compelling for quantum networking applications including blind quantum computing and quantum key agreement. However, transmitting cluster states over optical fiber has remained elusive with previous approaches, as losses scale exponentially with the number of photons. Here, we report the first transmission of a four-qubit cluster state to two parties over a partially deployed single-mode fiber link. The qubits of this state are encoded in two photons with multi-level time-bins. We directly generate the cluster state by exploiting coherent control of a parametric generation process, rendering a resource-intensive controlled-phase gate obsolete. To enable processing of this state, we introduce beam splitting for time-bins via chirped pulse modulation-a novel, reconfigurable Fourier-domain pulse shaping technique. We certify genuine multi-qubit entanglement and demonstrate one-way computing primitives on the transmitted cluster state. Our approach achieves the transmission of cluster states over optical fiber, establishing complex quantum resources fully compatible with telecommunication infrastructure.

2. Photo-guided azopolymer hydrogel actuators.
2. 光引导偶氮聚合物水凝胶驱动器PMID:日期:2026-09-17Amorphous azopolymers are fascinating materials that can be deformed in arbitrary directions by light. However, they are so far used mostly for microfabrication, to anisotropically reshape dry polymer structures - essentially as a post-processing fabrication step. This is because the effect is known to be a plastic deformation, wherein the azopolymer is photo-softened and selectively reflows along the direction of the illumination polarization, owing to its polarization-dependent functional dyes. Crucially, such deformations are retained in the dark and cannot easily be overwritten by subsequent illumination. Once reflowed, there is no memory of the initial state, and sequential photo-deformations are added on top of each other. Consequently, to use the directional photo-deformation of amorphous azopolymers for dynamic and reconfigurable micro-actuators, e.g., in lab-on-chip applications, one would need to face this lack of overwritability, in addition to a lower deformability of larger structures, sticky behavior, and poor mechanical stability in water for some uses. Here, we show how azopolymer-hydrogel composites overcome these issues. By embedding azopolymer nanoparticles in hydrogel matrices, directional photo-deformation is ensured by the particles, while the compliant gel matrix neatly propagates deformations to the overall composite. Elastic restoring forces from the matrix also promote overwritability, such that microfabricated gel cubes display ample and directionally reconfigurable photo-deformations in water. Sequential illuminations with orthogonal linear polarizations produce alternating linear deformations up to twice the pristine cube side length, using illumination intervals down to five seconds. Finally, we introduce polarization-controlled, fully closeable microwells, with potential applications in biotechnology, microfluidics, and drug release.

3. Hyperspectral dual-comb compressive ghost imaging with deep learning reconstruction.
3. 基于深度学习重建的高光谱双梳压缩鬼成像PMID:日期:2026-09-16Ghost imaging reframes image formation by replacing pixelated sensors with correlation measurements between structured illumination and a single-pixel detector, enabling capabilities that are difficult or impossible for conventional cameras. This powerful technique is inherently suited to imaging through scattering media, photon-starved scenes, and size-, access-, or cost-constrained platforms. Yet its broader adoption has been limited by a fundamental speed bottleneck: slow, sequential pattern projection via spatial light modulators or wavelength sweeps, which precludes real-time capture of dynamic scenes. Here, we overcome this fundamental bottleneck by combining dual-comb interferometry with compressive ghost imaging and deep learning reconstruction. Our method, hyperspectral dual-comb compressive ghost imaging, utilizes optical frequency combs to create wavelength-multiplexed speckle patterns that are delivered through a single-core fiber and detected by a single-pixel detector. This approach enables the simultaneous illumination and detection of hyperspectral speckle patterns without slow spatial light modulation or wavelength scanning, thereby allowing snapshot compression and the acquisition of image information using spatially non-resolved hardware. To decode the compressed signals, we develop a transformer-based deep-learning model capable of rapid, high-fidelity image reconstruction at sampling ratios below 1%. Our hardware-software co-design approach achieves high-fidelity dynamic ghost imaging at video rates and beyond while dramatically simplifying the optical front end, significantly advancing ghost imaging toward practical deployment in size- and access-constrained scenarios-from minimally invasive endomicroscopy to compact portable sensors.

4. Spatiotemporal all-optical diffractive neural networks empowered by spatiotemporal light field manipulation.
4. 由时空光场调控赋能的时空全光衍射神经网络PMID:日期:2026-09-16All-optical neural networks (AONNs) offer significant potential for feature detection and pattern recognition by leveraging light-speed processing, high parallelism, and low energy consumption. However, traditional AONNs are limited to spatial light intensity distributions for both inputs and outputs, restricting network learning to the spatial-only dimension. To overcome this, we propose a novel spatiotemporal AONN architecture that integrates the time dimension with the spatial domain, enabling simultaneous modulation of light field information across both time and space. In this configuration, the output spatiotemporal light field is spatially filtered, and its temporal signals are detected using a single-pixel detector. This approach integrates the temporal dimension as a core computational resource into the network, driving a paradigm shift in AONNs from "imaging detection" to "temporal analysis", effectively overcoming the speed bottleneck caused by the bandwidth limitations of traditional 2D array detectors. Moreover, experimental studies demonstrate that the system can accelerate the processing of real-world spatiotemporal lidar signals, facilitating the real-time reconstruction of multi-target moving scenes. Our innovative spatiotemporal AONN design offers enhanced flexibility, faster processing speeds, and superior performance, paving the way for more efficient and effective optical signal processing and computing applications.

5. Gigavoxel-scale multiple-scattering-aware lensless holotomography.
PMID:日期:2026-09-16Holotomography (HT) has revolutionized quantitative label-free 3D imaging, yet conventional lens-based implementations are fundamentally constrained in field-of-view (FOV) and imaging depth, limiting their utility for critical high-throughput applications in material and life sciences. Lensless HT (LHT) offers a promising alternative for large-volume examination, however existing approaches fail to accurately reconstruct highly scattering samples over extended depths, which remains a critical challenge in optical imaging field. Here, we introduce a gigavoxel-scale, multiple-scattering-aware LHT with a large FOV (surpassing 0.6 cm), millimeter-scale axial range, and pixel level (~2.4 µm) resolution. Our approach leverages a multi-wavelength, oblique-illumination hologram reconstruction and a robust, automatic illumination angle calibration, which are necessary for precise large-volume 3D holographic reconstruction. Moreover, we propose optimization-driven multi-slice tomographic framework to accurately capture multiple scattering effects outperforming first order Born/Rytov-based inversions. To rigorously validate our method, we reconstruct bespoke multi-layer two-photon polymerized test structure over a 1.7 mm imaging depth and 25 mm FOV, yielding an unprecedented 3D space-bandwidth product exceeding a gigavoxel level. Furthermore, we demonstrate for the first time on-chip label-free imaging of entire 500-µm-thick tissue slice of optically cleared mouse brain. With the proposed method, we aim to unlock powerful new capabilities for large-scale, quantitative, label-free 3D imaging across biomedicine, neuroscience, material sciences and beyond.

6. Breaking the phase noise-mode purity trade-off in long-loop OEOs via cascaded zero-dispersion recirculating loops.
6. 通过级联零色散循环回路打破长环光电振荡器中相位噪声与模式纯度之间的权衡PMID:日期:2026-09-16Optoelectronic oscillators (OEOs) generate microwave signals with ultra-low phase noise by incorporating long optical fiber loops as high-Q energy storage elements. However, long fiber loops reduce the free spectral range, leading to dense oscillation modes and requiring ultra-narrowband filters for single-mode operation, posing a long-standing trade-off between phase noise and mode purity. Here, we present a low-cost and scalable solution that breaks this trade-off. By inserting three cascaded zero-dispersion recirculating loops (ZD-RLs) into an amplified spontaneous emission (ASE)-based OEO, robust single-mode operation is achieved without using ultra-narrowband filters. The longest ZD-RL enhances the Q-factor of the microwave photonic filter (MPF) 4100 times, while the shorter loops increase the peak spacing within the MPF's passband to enable single-mode operation. This yields a sidemode suppression ratio of 72.7 dB and phase noise of -122 dBc Hz at 10 kHz offset at 10 GHz, matching commercial generators. This work shows that even low-cost broadband ASE sources can generate high-quality microwave signals, bridging the gap between laboratory OEO demonstrations and practical signal generators.

7. Narrowband, angle-stable, and highly efficient polariton organic light emitting diodes employing thermally activated delayed fluorescence.
7. 采用热活化延迟荧光的窄带、角度稳定且高效的极化激元有机发光二极管PMID:日期:2026-09-14Narrowband emission is crucial for next generation optoelectronic devices to satisfy demands for high color brilliance. Microcavities can narrow the emission spectra of organic light-emitting diodes (OLEDs) through the creation of resonant standing waves, independent of emitter material, enabling flexibility in molecular and device design. However, this introduces a strong angle-dependence of the perceived emission color. Utilizing strong light-matter coupling of cavity photons with the virtually angle-independent exciton, leads to exciton-polariton emission which offers a further reduction in linewidth and suppresses angular dispersion if tuned correctly. Creating polaritons in highly efficient materials such as thermally activated delayed fluorescence (TADF) molecules is however difficult as their low oscillator strengths intrinsically disfavor light-matter interaction. Here, we present the successful combination of a highly efficient but intrinsically broadband TADF emitter, CzDBA, with a strongly absorbing assistant strong coupling material, C545T, in a modified microcavity OLED structure. Through optimizing the assistant strong coupling layer architecture and integrating it with a highly conductive p-doped hole transport layer, we demonstrate polariton OLEDs with exceptionally narrowband, angle stable emission at external quantum efficiencies above 20% for both bottom- and top-emitting designs, more than doubling the performance compared to previously reported polariton OLEDs. Importantly, the fabrication of our polariton OLED stack does not require significant structural changes relative to existing microcavity OLEDs. Combined with their high efficiency, this paves the way for future utilization of polaritonic emission in commercial display applications.

8. Enhanced infrared-to-visible upconversion imaging via metasurface-lanthanide nanoparticle hybrid screens.
PMID:日期:2026-09-09Accessing the rich information carried by infrared light typically relies on bulky, complex optoelectronic systems. Lanthanide-based upconverting nanoparticles (UCNPs) offer a compelling alternative by converting infrared light into visible photons through nonlinear anti-Stokes processes. However, achieving strong upconversion under the low excitation intensities relevant to infrared vision remains challenging, motivating strategies to enhance light-matter interaction. Here, we demonstrate enhanced infrared-to-visible upconversion imaging enabled by integrating alloyed Yb/Er UCNPs with a resonant dielectric metasurface. The metasurface supports an optical resonance aligned with the UCNP excitation band, leading to over three orders of magnitude enhancement in upconversion emission. Crucially, flat-band angular dispersion of this resonance enables uniform enhancement across incident angles relevant to imaging, thereby preserving spatial frequency content and yielding sharp, high-contrast images. In light of ongoing advances in lanthanide-based materials, this metasurface-UCNP hybrid screen provides a promising platform for compact, detector-free, and scalable infrared imaging technologies based on optical upconversion.

9. Tuning superposition of multiple Fano interferences for efficient plasmon resonance energy transfer to the assembled molecules.
PMID:日期:2026-09-09Plasmon-exciton Fano interference provides an efficient channel for coherent energy transfer, and the plasmon resonance energy transfer (PRET) peak is usually observed around the Fano dip at the exciton resonance. In this work, we achieve tunable multiple Fano interferences and multichannel PRET by strategically coupling five excitonic resonances (labeled as M, D, D, H, and J) of assembled IR806 molecules with Au nanobipyramids and nanorods (AuNBPs and AuNRs, respectively). Notably, owing to orientation-dependent molecule-plasmon coupling in the IR806/AuNBP hybrids, we observe two PRET peaks with opposite signs of Fano factor . One PRET peak remains fixed near the J-aggregate exciton resonance at ~900 nm, whereas the other is located around the plasmon resonance and tuned from 710 to 920 nm. The total PRET reaches a maximum when the two PRET peaks are tuned into spectral overlap. Furthermore, our newly developed semiclassical model quantitatively reproduces these features, which reveals that PRET enhancement arises from the superposition of multiple Fano interferences. These findings provide a novel strategy to enhance the efficiency and tunability of the PRET, opening avenues for advanced applications in ultrafast optical information processing and highly sensitive photodetectors.

10. Exceptional points, lasing, and coherent perfect absorption in Floquet scattering systems.
PMID:日期:2026-09-09Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of electromagnetic waves from spatially finite PTCs using the multispectral Floquet scattering matrix, which naturally incorporates the frequency-mixing processes intrinsic to such systems. For dispersionless, real, and time-periodic permittivities, this matrix is pseudounitary. Here, we demonstrate that this property leads to multiple symmetry-breaking transitions: for increasing driving strength, scattering matrix eigenvalues lying on the unit circle (unbroken symmetry regime) meet at exceptional points (EPs), where they break up into inverse complex conjugate pairs (broken symmetry regime). We identify the symmetry operator associated with these transitions and show that, in time-symmetric systems, it corresponds to the time-reversal operator. Remarkably, at the parametric resonance condition, one eigenvalue vanishes while its partner diverges, signifying simultaneous coherent perfect absorption (CPA) and lasing. Since our approach relies solely on the Floquet scattering matrix, it is not restricted to a specific geometry but instead applies to any periodically time-varying scattering system. To illustrate this universality, we apply our method to a variety of periodically time-modulated structures, including slabs, spheres, and metasurfaces. In particular, we show that using quasi-bound states in the continuum resonances sustained by a metasurface, the CPA and lasing conditions can be attained for a minimal modulation strength of the permittivity. Our results pave the way for engineering time-modulated photonic systems with tailored scattering properties, opening new avenues for dynamic control of light in next-generation optical devices.
