However, supercontinuum from integrated waveguides has been limited to >330 nm in the ultraviolet-A band because of material dispersion and absorption. Here, we demonstrate unprecedented ultraviolet-C-to-mid-infrared supercontinuum on a chip, leveraging the exceptional transparency window and second-order nonlinearity of lithium tantalate (LT). A key innovation is the introduction of chirped periodically poled LT with submicron ferroelectric domains. Utilizing 3-wave-mixing processes under quasi-phase-matching conditions, we created the shortest ultraviolet wavelength ever reported from a chip-below 270 nm-while reaching 2400 nm in the mid-infrared, covering more than three octaves with just 100 pJ pulse energy on a chip for the first time. It's the first on-chip supercontinuum fully covering the ultraviolet-A/B bands while extending into the ultraviolet-C band.

This potential, though, has been fundamentally constrained by the intrinsic latency and power limitations associated with electronic signal processing. Here, we propose an all-optical fiber sensing architecture with in-sensor computing (AOFS-IC) that achieves fully optical-domain sensing signal demodulation at the speed of light. By integrating a scattering medium with an optimized diffractive optical network, AOFS-IC enables linear mapping of physical perturbations to detected intensity, and sensing results can be directly read out without electronic processing. The proposed system maintains high accuracy across various sensing tasks, providing sub-nano strain resolution and 100% torsional angle classification accuracy, as well as multiplexed sensing of multiple physical quantities, and performing multi-degree-of-freedom robot arm monitoring. AOFS-IC eliminates computing hardware requirements while providing <3 ns demodulation delay, which is more than 2 orders of magnitude faster than conventional fiber optic sensing systems. This work demonstrates the potential of next-generation optical sensing systems empowered by all-optical computing and paves the way for expanded applications of fiber sensing through the integration of fully optical components, ultrafast measurement speed, and low power consumption.</p>","PeriodicalId":18093,"journal":{"name":"Light, science & applications","volume":"15 1","pages":""},"PeriodicalIF":23.4,"publicationDate":"2026-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13201864/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148015616","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}

Tomographic Volumetric Additive Manufacturing (TVAM) employs a digital micromirror device (DMD) to project amplitude light patterns into rotating resin volumes, producing 3D geometries through photopolymerization. Typically, the light projection efficiency in such binary amplitude modulator-based systems is below a few percent. Recent advancements introduced phase encoding in TVAM using binary amplitude modulators and the Lee Hologram method, increasing axial control and boosting light efficiency to about 10%. In this work, we present the first 3D printing platform utilizing a phase light modulator (PLM), based on an array of micro-electro-mechanical piston mirrors. Compared to amplitude encoding, phase encoding with the PLM yields a 70-fold increase in laser power efficiency. By coupling this efficient light engine with a speckle reduction method in holographic volumetric additive manufacturing (HoloVAM), we experimentally demonstrate printing 3D objects across different scales from hundreds of micrometers to centimeters and with various materials from acrylate-based resins to soft hydrogels, including cell-laden hydrogels with a concentration of 1 million cells per mL.

In this work, we present MANTIS (Multispectral All-Depth meta-opTic Imaging System), a co-designed computational microscopy imaging system that achieves extended depth-of-field from a single acquisition without axial scanning. MANTIS combines a learned meta-optic with a physics-guided neural network trained end-to-end to reconstruct sharp multispectral images from depth, and wavelength-dependent blurred sensor measurements. We experimentally demonstrate a 50 μm extended depth of field at NA 1.1, corresponding to an 82-fold increase over a conventional wide-field microscope. In addition, simulations show that MANTIS can target different depth-of-field ranges, with the expected trade-off that larger depth-of-field ranges come at a cost in reconstruction fidelity.
