However, advanced fabrication processes have been developed to enable the demonstration of highly efficient 270 nm UVC micro-LEDs and large-format UVC micro-LED displays with high resolution for maskless photolithography. Optical and electrical characterizations were performed on UVC micro-LEDs with sizes ranging from 3 µm to 100 μm to evaluate these emerging devices. The 3 μm device achieved a record-high peak external quantum efficiency of 5.7% and a maximum brightness of 396 W cm–2. Moreover, 2,540 pixels per inch parallel-connected UVC micro-LED arrays featuring rear-side reflection layers exhibited emission uniformity and collimation. UVC micro-LED displays, with a resolution of 320 × 140, were explicitly designed for maskless photolithography applications utilizing a customized integrated circuit driver for optimal performance. The UVC micro-LEDs and UVC micro-displays provide sufficient doses to fully expose the photoresist film within seconds, owing to their enhanced current spreading uniformity, improved heat dispersion and superior light extraction efficiency. This work may open a path to maskless photolithography, potentially leading to revolutionary developments in the semiconductor industry.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"6 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435988","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}

However, the challenge of co-integrating the multiple components of high-performance laser systems has left application of these nanoscale devices thwarted by bulky laser sources that are orders of magnitude larger than the devices themselves. Here we show that the two main components for high-performance lasers—noise reduction and isolation—can be sourced simultaneously from a single, passive, CMOS-compatible nanophotonic device, eliminating the need to combine incompatible technologies. To realize this, we take advantage of both the long photon lifetime and the non-reciprocal Kerr nonlinearity of a high-quality-factor silicon nitride ring resonator to self-injection lock a semiconductor laser chip while also providing isolation. We also identify a previously unappreciated power regime limitation of current on-chip laser architectures, which our system overcomes. Using our device, which we term a unified laser stabilizer, we demonstrate an on-chip integrated laser system with built-in isolation and noise reduction that operates with turnkey reliability. This approach departs from efforts to directly miniaturize and integrate traditional laser system components and serves to bridge the gap to fully integrated optical technologies.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"193 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142436284","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}

Dynamic reconfigurability of photonic circuitry is key to controlling the walk and retrieving its full operation potential. Universal quantum processing schemes based on time-bin encoding in gated fibre loops have been proposed but not demonstrated yet, mainly due to gate inefficiencies. Here we present a scalable quantum processor based on the discrete-time quantum walk of time-bin-entangled photon pairs on synthetic temporal photonic lattices implemented on a coupled fibre-loop system. We utilize this scheme to path-optimize quantum state operations, including the generation of two- and four-level time-bin entanglement and the respective two-photon interference. The design of the programmable temporal photonic lattice enabled us to control the dynamic of the walk, leading to an increase in the coincidence counts and quantum interference measurements without recurring to post-selection. Our results show how temporal synthetic dimensions can pave the way towards efficient quantum information processing, including quantum phase estimation, Boson sampling and the realization of topological phases of matter for high-dimensional quantum systems in a cost-effective, scalable and robust fibre-based setup.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"28 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431140","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}

However, current imaging probes struggle to simultaneously achieve high sensitivity, deep-tissue penetration and tissue specificity. Here we report size- and shape-resolved fluorescent DNA framework (FDF) dots with tail emission in the second near-infrared window (1,000–1,700 nm, NIR-II), which enable near-single-cell-level, tumour-targeting deep-tissue (~1 cm) NIR-II imaging in tumour-bearing mouse models. The construction of DNA frameworks with embedded hydrophobic nanocavity results in the non-covalent encapsulation of a designed NIR-Ib (900–1,000 nm) probe (dye Sq964). The FDF dots exhibit high water solubility, brightness and photostability. We find that the stable tumour retention of FDF dots with enhanced signal intensity arises from their shape-dependent accumulation in tumour cells. FDF-dot-based cancer imaging reveals in vivo sensitivity down to ~40 tumour cells, high tumour-to-normal tissue ratios up to ~26 and long-term imaging over 11 days. We also demonstrate NIR-II-image-guided breast cancer surgery with the complete excision of metastases with a minimum size of ~53 μm (~20 cells).","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"2672 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142404926","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}

Although the working mechanisms of TSC have been demonstrated, the roles that the intrinsic molecular skeleton and extrinsic aggregates play remain unclear. Here four trinaphthylmethanol isomers and four trinaphthylmethane (TNM) isomers with varying connecting sites of naphthalene were synthesized, and their photophysical properties were systematically investigated. The strength of TSC was found to rise from 222-TNM to 111-TNM with the increased number of 1-naphthalene units. In particular, 111-TNM was found to support efficient long-wavelength clusteroluminescence with an absolute quantum yield of 55%. Experimental and theoretical results revealed that the inherent attribute of robust intramolecular interactions within individual molecules is fundamental for ultrastrong TSC, and intermolecular interactions play an auxiliary role in fortifying and stabilizing intramolecular interactions. This work reveals the intrinsic and extrinsic factors for manipulating TSC and provides a reliable strategy for constructing non-conjugated luminogens with efficient clusteroluminescence. Efficient organic emitters of ultraviolet light are realized by the use of isomers that exhibit strong through-space conjugation.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 11","pages":"1185-1194"},"PeriodicalIF":32.3,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142404927","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}

It has been shown that quantum mechanics offers some advantages for this type of task. A promising model for randomness manipulation is provided by Bernoulli factories—protocols capable of changing the bias of Bernoulli random processes in a controlled way. At first, this framework was proposed and investigated in a fully classical regime. Recent extensions of this model to the quantum case showed the possibility of implementing a wider class of randomness manipulation functions. We propose a Bernoulli factory scheme with quantum states as the input and output, using a photonic-path-encoding approach. Our scheme is modular and universal and its functioning is truly oblivious of the input bias—characteristics that were missing in earlier work. We report on experimental implementations using an integrated and fully programmable photonic platform, thereby demonstrating the viability of our approach.
