Here, a Depth Heterogeneity Self‐supervised Neural Operator (DHSNO) is proposed, a multi‐physics heterogeneous model integrated neural architecture tailored to correct turbulence wavefronts in a single pass without the need for labeled training data. By leveraging dual‐mode intensity detection in a depth‐heterogeneous receiver, DHSNO inherently regularizes the ill‐posed wavefront retrieval problem to deliver robust, high‐accuracy, and low‐latency reconstruction. This capability is validated in both an emulated 50‐meter underwater turbulence channel and a real‐world 5‐meter underwater salinity‐gradient channel, where DHSNO achieves a normalized residual wavefront error below 0.06 with an inference time of 3.6 ms under varying turbulent strengths. Furthermore, this prototype system enabled 12‐Gb/s 4K‐120fps video transmission with near‐perfect fidelity (SSIM > 0.9999) under severe turbulence conditions. These findings not only advance the state‐of‐the‐art in adaptive optics but also provide a scalable framework for next‐generation free‐space and underwater optical systems, underscoring the transformative potential for turbulence correction of integrating physical constraints with data‐driven neural networks.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"67 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612795","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}

In this study, dual‐band EIT is demonstrated by strategically engineering the coupling between a magnetic toroidal dipole (TD) Mie resonance and two quasi‐bound states in the continuum (QBICs) within all‐dielectric metasurfaces. Through deliberate symmetry breaking in the cuboid unit cell—achieved via off‐center holes or U‐shaped configurations—two BICs, predominantly governed by electric TD and magnetic quadrupole modes, are successfully transformed into QBICs with high quality (Q) factors. These QBICs are then coupled to a low‐Q magnetic TD Mie resonance, resulting in the emergence of dual‐band EIT. The corresponding group delays reach up to 9.51 ps (Q = 7,674) and 5.69 ps (Q = 3,631), respectively, and diverge when the Q‐factors approach infinite. Furthermore, the dual‐band EIT with high Q‐factors is experimentally validated by fabricating a series of silicon metasurfaces and characterizing their transmission spectra. Excellent agreement is found between numerical simulation and experimental measurement. Measurement results reveal that both the resonance wavelengths and Q‐factors of the dual‐band EIT are precisely tuned by adjusting the asymmetry parameters. These findings hold significant promise for applications in multi‐wavelength slow light devices and biosensing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"109 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612811","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}

Herein, a plasma‐assisted interfacial engineering is proposed to enhance valley polarization and valley splitting in MoS2/AlN heterostructure by modifying the surface configurations of AlN substrates. The experimental results show that after the optimized N2‐plasma treatment, the AlN surface becomes smoother with a decreased migration barrier, thereby facilitating the growth of high‐quality MoS2. The valley splitting and degree of valley polarization in the optimal sample reach 7.96 meV (the corresponding Landé g factor is 19.6) and 33.8% at −7 T, which are 16.0‐ and 1.0‐fold higher than those in the untreated MoS2/AlN heterostructure, respectively. Theoretical simulations indicate that the enhanced spin‐valley properties are predominantly ascribed to the AlN surface magnetism induced by the hybridization of Pz and Py orbitals of surface N and O atoms. This work opens a new avenue for manipulating spin‐valley properties in 2D materials via interfacial engineering.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"1 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612797","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, their efficiency in SHG is limited by the centrosymmetric nature of their crystal structures, and thus achieving SHG from 3D perovskites by breaking their inversion symmetry remains a formidable challenge. In this work, the precision and versatility of the femtosecond (fs) pulse laser writing technique are leveraged to fabricate microstructures of hybrid and inorganic perovskites with non‐centrosymmetric. These microstructures exhibit a strong SHG signal across a broad wavelength range (790–1210 nm), while the pristine 3D perovskites do not show any SHG. The enhanced SHG response is attributed to the laser‐induced modifications of the A‐site cations (MA, Cs) and halide defects in the pristine 3D perovskites, which disrupt the inversion symmetry. Furthermore, the potential of using non‐centrosymmetric microstructures of perovskites for ultrafast pulse characterization via the Frequency‐Resolved Optical Gating technique is demonstrated. These findings highlight the precise control of non‐centrosymmetric states using fs lasers, paving the way for the design and utilization of perovskites in advanced nonlinear optical and photonic applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"47 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593845","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}

Metasurface‐based methods achieve nanometric resolution but are hindered by fabrication complexity, limited dynamic range, and ambiguity in absolute displacement measurement. An ultrasensitive vector displacement sensor utilizing liquid crystal optical elements (LCOE) under vector beam illumination is presented. By mapping the transverse displacement to the polarization change of a radial vector beam, the displacement length can be directly inferred using Malus' law, and the displacement direction can be easily determined from the rotation of the vector beam speckle. Remarkably, uncertainties of 47 and 55 pm are achieved over centimeter‐scale ranges, with step sizes of 10 and 5 nm, respectively. This method combines nanometric resolution, an extended dynamic range, and compactness, providing innovative metrological principles for next‐generation precision measurement applications. The integration of LCOEs and vector beams enables absolute displacement measurement without the need for complex nanofabrication, overcoming critical limitations of current technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"690 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593897","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}

Despite its significance, the prevailing mid‐infrared absorption spectroscopy systems for protein analysis are hampered by instrument complexity, high costs, and limited sensitivity, which impede their widespread application. Here, a high‐sensitivity protein mid‐infrared laser spectroscopy sensor using a quartz hollow waveguide as a microfluidic reaction vessel is proposed. On the ultra‐long reaction path provided by quartz hollow waveguides, gold core–shell nanoparticles are modified to induce surface‐enhanced infrared absorption (SEIRA) effect, and further biotin functionalization to obtain streptavidin capture capability. Notably, the gold core–shell particles are optimized based on the time‐coupled mode theory (TCMT) to better match the hollow waveguide transmission structure. The results demonstrate that the detection limits of streptavidin in the amide I and amide II bands are 35.68 and 38.69 ng mL−1, respectively. The proposed surface enhanced hollow waveguide realizes the simultaneous detection of the lowest detection limit of the protein amide I and amide II bands by infrared spectroscopy, which provides a powerful platform for protein analysis.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594057","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}
