In this study, a novel and highly efficient yellow phosphor (Ba3Sc2(BO3)4: Eu2+, BSBO: Eu2+) is synthesized via the high‐temperature solid‐phase method for the first time. The excitation spectrum of this phosphor ranges from 225 to 480 nm, with a peak at 365 nm. The emission spectrum ranges from 450 to 720 nm, peaking at 555 nm, with a full width at half maximum (FWHM) of 113 nm. BSBO: Eu2+ shows outstanding quantum efficiencies (IQE = 94.3%, EQE = 33.3%). The emission spectrum and luminescent color can be tuned through cation substitution. The thermal stability of BSBO: Eu2+ is significantly enhanced by the partial replacement of Sc ions with smaller Al and Ga ions. To illustrate its practical application potential in full‐spectrum lighting, BSBO: Eu2+ is combined with commercially available blue and red phosphors, resulting in a WLED warm light source with an outstanding color rendering index (Ra) of 94.4% and a correlated color temperature (CCT) of 3865 K. These results highlight the substantial potential of BSBO: Eu2+ in full‐spectrum lighting applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"32 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979907","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}

The organic–inorganic hybrid π–π stacking is an effective method to design high-performance NLO crystals. Herein, rigid inorganic π-conjugated units (CO3 and NO3, the symbol is π) and organic π-conjugated dimers (biguanide group, the symbol is π^) are employed for stacking, resulting in the compounds of NH[C(NH2)2]2(NO3)2 and {N[C(NH2)2]2}2CO3 through π--π^ interaction. Both compounds exhibit strong linear optical properties—transparency: 318 nm and birefringence: 0.122@550 nm for the former; transparency: 258 nm and birefringence: 0.232@550 nm for the latter—and NLO effects (3.5 × KH2PO4 (KDP) and 5 × KDP, respectively). Theoretical calculations reveal that strong linear and NLO properties mainly derive from the interactions of multiple hydrogen bonding and π--π^ stacking. Interestingly, deprotonatable N[C(NH2)2]2 organic π-conjugated dimers demonstrate higher polarizability anisotropy and hyperpolarizability than their protonated NH[C(NH2)2]2 counterparts, resulting in enhanced macroscopic linear and NLO performance. This offers an opportunity to understand π–π stacking and provides a new strategy for enhancing the linear and NLO properties of the material.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"2 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933231","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}

Recently, bilayer metasurface strategies have enabled significant enhancements in polarization and nonreciprocal modulations, facilitating applications in holographic display and optical communications. However, a more intuitive Jones matrix analysis is needed, and the current pixel-wise design of bilayer metasurfaces necessitates precise nanofabrication and alignment, leading to increased costs and technical challenges. In this paper, cascade metasurfaces design strategies for vectorial wavefront manipulations with misalignment robustness are investigated. First, an intuitive visualization method for the Jones matrix is established, based on the analysis of polarization eigenstates, polarization dichroism, and phase modulations. On this basis, a pixel-wise design approach of cascaded metasurfaces aimed at sophisticated vectorial spatial light modulation is proposed. This approach achieves assembly tolerances more than one order of magnitude higher than those of the control group, by employing a specialized spatial frequency optimization. Specifically, both the cascaded and individual metasurfaces are predesigned to serve distinct functions. Multichannel vectorial wavefront multiplexing and polarization encryption are all realized. It is believed that the work offers valuable insights into sophisticated polarization modulation techniques and the cost-effective design of multilayer metasurfaces.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"123 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940280","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 lattice deformations of BPLCs widely exist in various applications, there remains a challenge to understanding the quantitative relationship between different deformation modes and resulting 3D diffractive optics. Herein, a universal simulation strategy is proposed based on spatial geometry modeling to enable real‐time computation of dynamic optical responses in BPLCs. This framework systematically interprets and predicts the optical characteristics under both symmetric lattice deformations (governed by chiral dopant concentration) and asymmetric lattice deformations (induced by phase separation or component dispersion). Differentiated nonlinear optical effects are revealed for these deformations in Kossel diffraction analysis. Furthermore, anisotropic modulation of surface/sectional structural colors (photonic bandgaps) and angle‐dependent control over the full spatial light field is demonstrated by tailoring interplanar spacing and facet orientation within the lattice symmetry constraints. This study establishes a theoretical foundation for designing next‐generation BPLC‐based photonic devices, including holographic displays, all‐optical switches, integrated waveguides, and 3D lasing systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"21 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932649","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}

Structures with spatial singularities, such as metallic wedges, are crucial for achieving nanoscale focusing, leading to significant advancements in the sensing and imaging of subwavelength structures. In this study, the spatiotemporal analogue of the wedge structure, i.e. a dielectric medium sandwiched between two subluminal interfaces with distinct velocities, is exploited to focus propagating waves to deep subwavelength scales, thereby achieving the spatiotemporal superfocusing. In this configuration, an incident pulse undergoes cascaded compression due to the Doppler effects, accumulating to extreme focusing and enhancement as it approaches the spatiotemporal vertex. Remarkably, unlike the field localization in conventional superfocusing, the compressed light in spatiotemporal wedges experiences significant amplification and then couple to the far field in free space. The findings represent an indispensable paradigm for extreme concentration and amplification of propagating waves in space‐time dimensions.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"22 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932648","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}

The device leverages the polarized charge of LiNbO3 to modulate the conductance carriers in graphene, thereby achieving an amplified photoresponse in the LWIR range of 8 to 11 µm. Notably, at room temperature, the device exhibits a superior responsivity of 48 A W−1 under blackbody radiation, surpassing the performance of previous 2D materials-based LWIR detectors. Remarkably, it can identify the radiation signals of a human finger, a feat previously considered challenging for devices relying on graphene or other 2D materials.

Here, it is demonstrated that dark and asymmetric qBICs arise in the optical domain in Si tilted nanodisk metasurfaces, due to the spectral overlap of in‐plane and out‐of‐plane dipolar resonances in these meta‐atoms, similar to so called Brewster qBICs in the microwave regime for single‐magnetic‐resonance, tilted microdisks, arising at the tilt angle. Using a coupled dipole model, it is shown that optical dark qBICs occur for tilted nanodisks at modified Brewster angles that can differ significantly from the nanodisk tilt angles, , due to the hybridization of in‐plane and out‐of‐plane dipolar resonances. If light is incident at , qBIC excitation is forbidden and the metasurface is transparent; counterintuitively, for , the qBIC is indeed excited but the metasurface remains also fully transparent, so that such qBIC excitation is cloaked. Numerical calculations confirm the asymmetric character of these qBICs, demonstrating that the cloaked qBIC largely enhances near‐fields and emerges in the extinction only when absorptive losses are present in the nanodisks. Finally, a practical metasurface design is proposed, amenable to fabrication, supporting cloaked qBICs. The rich phenomena associated with such cloaked qBICs make them highly suitable for tuning or switching nano‐optical devices (between on/off qBIC states with negligible reflection), offering promising applications for enhanced light–matter interactions at the nanoscale.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"7 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932647","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}
