However, previous BBD emitters lack consideration of azimuth dependence, and the waveband is limited. Herein, we design a metal–insulator–insulator–metal (MIIM) thermal emitter for achieving polar-azimuthal selective emission within the 8–14 μm atmospheric window, namely, broadband bidirectional thermal emission. The proposed MIIM structure consists of aluminum (Al) stripes on the top, beneath aluminum oxide (Al<sub>2</sub>O<sub>3</sub>) and silicon oxide (SiO) films, and an Al substrate. We explicitly present the design procedure of the MIIM structure to achieve broadband bidirectional emission and reveal the underlying mechanisms. Results indicate that the intrinsic absorption of the dielectric layers, localized surface plasmons (LSPs), and magnetic polaritons (MPs) synergistically promote the broadband bidirectional emission of the MIIM structure, resulting in bidirectional thermal emission within two well-constrained solid angles with marginal angular dispersion. This work reports a high-performance broadband bidirectional emitter and provides new insights into controlling polar-azimuth emissivity through the superposition and coupling effects of LSPs and MPs, with potential applications in thermal imaging and camouflage.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"17 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766419","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}

Superconducting microwave qubits operating in cryogenic environments have emerged as promising candidates for quantum processor nodes. However, scaling these systems is challenging because they require bulky microwave components with high thermal loads that can quickly overwhelm the cooling power of a dilution refrigerator. Telecommunication frequency optical signals, however, can be fabricated in significantly smaller form factors to avoid challenges caused by high signal loss, noise sensitivity and thermal loads due to their high carrier frequency and propagation in silica optical fibres. Transduction of information by means of coherent links between optical and microwave frequencies is therefore critical to leverage the advantages of optics for superconducting microwave qubits, while also enabling superconducting processors to be linked with low-loss optical interconnects. Here, we demonstrate coherent optical control of a superconducting qubit. We achieve this by developing a microwave–optical quantum transducer that operates with up to 1.18% conversion efficiency with low added microwave noise, and we demonstrate optically driven Rabi oscillations in a superconducting qubit.</p>","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"20 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758124","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}

Until now, however, it still remains a significant challenge to achieve an active microlaser with a quality factor of up to 10<sup>4</sup> and heterogeneous integration of multiple broadband wavelength-tunable microlasers for Si-based PICs. Here, a scalable strategy is reported to realize simultaneous integration of multiwavelength GaN-based microdisk laser arrays on Si(100) substrates. The microlaser exhibits a high-quality factor of 13 138 and a low threshold density of 57.85 µJ cm<sup>−2</sup>. By precisely modulating the microdisk size and/or shape and thus the corresponding cavity loss, the lasing wavelength can be dynamically tuned over a large spectral range from 455 to 503 nm, which is physically unraveled by the gain profile shifting for different threshold energy levels conditions. This study opens a new path toward the realization of on-chip integrated broadband multiwavelength laser sources for Si-PICs platform, where only an epi-wafer and a single round of wafer bonding processes are needed.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"27 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758688","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}

Computational photography algorithms can enhance image quality in complex environments. However, conventional methods may suffer from imprecise models or priors, while deep learning ones face limitations in data-unaccessible scenarios. To address these challenges, we present a generalized augmenting technique for computational photography, termed Linear Optimization of Neurons (LION), designed to perform case-specific optimization while maintaining the network’s structure and weights. We deeply investigated the robust semantic constraints on the deep feature domain and found that linear transformations of pre-trained convolutional neural network (CNN) features can enhance the quality of output images without necessitating modifying network architecture. Building upon this finding, we developed a generalized workflow to augment both conventional and deep learning methods. We first fit the encoder–decoder CNN to output the pre-reconstruction from an off-the-shelf method. Then, fixing the network weights, we optimize the linear combinations of features using a generalized color and texture regularization to further enhance the output image quality. A series of experiments on various public datasets confirmed the effectiveness of this technique, particularly in underwater and low-light imaging scenarios.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"188 ","pages":"Article 112834"},"PeriodicalIF":4.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
