A powerful framework for describing these cavities is mean‐field theory, which captures the averaged effect of internal dynamics over a round trip. Lasers based on media with slow gain dynamics can be described by solving the population over many round trips, while lasers based on fast gain media can be described by adiabatic elimination. However, most gain media actually have both fast and slow components, and effects often ascribed to fast gain media can also arise in slower gain media. An operator‐based mean‐field theory is developed that non‐adiabatically describes the dynamics of bidirectional active cavities, both fast and slow. This first‐principles formalism provides a semi‐exact replacement for the Maxwell–Bloch equations and accommodates non‐trivial gain lineshapes and population dynamics. As an example, this formalism is used to establish an additional constraint on the formation of frequency‐modulated combs. These results are broadly applicable to bidirectional and unidirectional active cavities alike (including both Fabry–Pérot and ring cavities), and they extend naturally to nearly any chip‐scale laser system.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"90 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500762","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}

Such metasurfaces often require precise and complex chiral structural designs and activation, which limit their practical applications. Here, a simple and achiral dielectric metasurface based on guided mode resonance (GMR) is proposed and experimentally demonstrated for achieving arbitrary polarization and CD tuning. A truncated dielectric grating (TDG) structure involving only three parameters is employed to construct a complete and continuous variation of polarization modes around Γ‐point. The proposed achiral metasurface can achieve a near‐perfect CD peak of 0.97 at 1.55 µm and also continuous tuning of CD from −0.97 to 0.97 by simply changing the azimuth angle of the TDG at a designed incident angle. Furthermore, under a linearly polarized incidence, the output polarization state can be arbitrarily tuned from linear to either of two orthogonal circular polarization. The proposed metasurface with minimalist achiral and dielectric structure that can significantly reduce both the design and the fabrication complexity provides a novel paradigm for various polarization manipulation in fields of spin‐selective wavefront shaping, angular sensing, optical security, and other dynamic chiral optical devices.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"18 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503453","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, it is still a great challenge to prepare CsPbBr3 PQDs that boast both superior photoluminescence quantum yield (PLQY) and ultrahigh stability. Herein, Mg‐doped silicalite‐1 (MS‐1) zeolite is employed as a matrix to develop a CsPbBr3@MS‐1 composite through a straightforward thermal diffusion strategy, achieving ultrahigh PLQY of 97.4% for bright green solid‐state fluorescence emission. The PLQY of CsPbBr3@MS‐1 composite remains over 90% even after 6 months in air. Additionally, the composite demonstrates outstanding luminescent stability against heat, ultraviolet (UV) irradiation, and erosion effects of both acidic and alkaline solutions. The synergistic protection from both the dense zeolite shell and the passivation by magnesium ions detached from the framework facilitates reduction of intrinsic bromine vacancies on the CsPbBr3 surface, thereby minimizing nonradiative recombination centers and resulting in ultrahigh stability and PLQY. A standard white light emitting diode (LED) with a maximum luminous efficiency of 63.12 lm W−1 and outstanding stability is constructed based on CsPbBr3@MS‐1 composite, commercial red phosphor, and a blue chip.

The underlying causes of these limitations are not well understood, and the methodology for simultaneously improving these aspects remains to be explored. Herein, an all‐inorganic ordered‐disordered heterojunction interface is presented with high local structural evolution activity, consisting lattice‐disordered W18O49 functionalized with crystalline N‐doped TiO2 (TiO2:N@W18O49‐a). This configuration enables over 80% photochromic contrast within 5 s under UV irradiation and complete self‐bleach within 90 s. In situ irradiation (ISI)–electron paramagnetic resonance and ISI–X‐ray photoelectron spectroscopy combined with DFT calculations reveal that this interface induces the localization of photogenerated electrons and promotes the formation of a unique color center configuration (Ti‐Ovac‐W), significantly enhancing both the photochromic speed and the photochromic contrast. Furthermore, this ordered‐disordered interface configuration upshifts the d‐band center of W, facilitating the adsorption of O2 and thereby ensuring a highly customizable self‐bleaching rate. These advantages establish a foundation for advanced optical applications, and the potential applications of TiO2:N@W18O49‐a in photochromic smart windows, information encryption, and information storage are demonstrated.

The 2D/3D hybrid‐dimensional heterostructure, featuring a lattice‐mismatch‐free interface, successfully integrates the superior electrical properties of 2D materials with the high light absorption and excellent sensitivity of 3D materials, providing a novel platform for developing high‐performance optoelectronic devices.

Specifically, the device demonstrates a high responsivity of 2343 V/W, an ultrafast response speed ≈60 µs, and an exceptional detectivity of ≈1010 Jones under 780 nm illumination. Notably, it maintains a responsivity exceeding 60 V/W and a rapid response time of 54 µs even at 3500 nm.

Here, a strategy using double perovskite Cs2AgInCl6 nanocrystals co‐doped with Bi3+, Yb3+, and heavily doped Er3+ is demonstrated to achieve efficient long‐wavelength NIR emission. The double perovskite host with self‐trapped excitons (STEs) property serves as an energy reservoir for subsequent transfer to Er3+. Bi3+ doping induces lattice distortion, enhancing STEs formation and breaking octahedral symmetry around Er3+ to boost the 4I13/2→4I15/2 transition. Yb3+ as a sensitizer, bridges the energy gap between STEs and Er3+, facilitating efficient energy transfer to populate Er3+ metastable states. This synergistic mechanism, enabled by double perovskite's broadband emission and homovalent doping tolerance, allows heavy Er3+ loading (≥20% molar‐ratio), driving a photoluminescence quantum yield of 31% at 1540 nm.

Current advanced shape sensing solutions utilize highly integrated fiber Bragg gratings (FBGs) in single‐mode fibers, which are the smallest type of shape sensors. A significant challenge with these miniature sensors is the limited number of Bragg wavelengths, which restricts the resolution and length of the measurement. Here, a single‐channel single‐fiber shape sensing scheme is proposed based on cascaded cladding fiber Bragg gratings (cl‐FBGs) fabricated using femtosecond laser direct writing. Each sensing point consists of four mutually orthogonal cl‐FBGs with different wavelengths, which are then parallelly replicated along the fiber axis to form the cascaded structure. This design overcomes the limitation of wavelength channels, enabling the resolution of 104 cl‐FBGs using just four characteristic wavelengths. It is demonstrated that our sensing fiber, containing 26 sensing points, successfully reconstructs deformations of both 2D and 3D curves. Furthermore, it is showed that the intensity demodulation‐based shape sensing scheme exhibits minimal dependence on strain and temperature. This compact, interference‐resistant, and high‐precision shape reconstruction approach represents a significant advancement in micro‐scale spatial shape sensing, akin to applications in microvascular systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"148 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488510","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}
