However, achieving high sensitivity and stability while effectively suppressing background interference in complex target imaging presents several significant challenges. Herein, two different metasurface structures (type I and type II) and different Cs0.05(FA0.85MA0.15)0.95Pb(I0.85Br0.15)3 (CsFAMA) thicknesses of THz polarization detectors are designed and fabricated, which based on CsFAMA /poly(3,4‐ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS)/ Metasurface composite structures. The type II device with a 0.8 µm CsFAMA thickness achieved optimal performance under 0.1 THz laser irradiation, with a responsivity of 435.81 V W⁻¹, a polarization ratio of 2.53, and a fast response time of 93 µs, attributed to the heterojunction and metasurface‐localized thermoelectric field. In addition, stability tests are carried out under standard conditions, the polarization ratio decreased by only 3%, and further accelerated aging tests at high temperature and high humidity revealed that the polarization ratio decreased by 15% and 27%, respectively. The polarization imaging clearly and distinctly shows three different complex patterns even after 360 days of air exposure. This study highlights the potential of CsFAMA/metasurface composite devices for highly sensitive and stable THz polarization detection and imaging applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"17 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479077","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}

A plasmonic photothermoelectric metasurface based monochromatic polarization detector with a high polarization ratio () is proposed and simultaneously realize linear sensing with the polarization angle sensitivity of 0.67 µA (W·deg)−1 by the excitation of high‐Q quasi‐BICs resonances. In general, with the purpose to achieve the maximal circular dichroism (CD) response, symmetry breaking is introduced, which inevitably leads to the radiative losses and the significantly decreased Q‐factor, therefore fundamentally limiting the simultaneous realization of polarization modulation and high monochromaticity. Herein, a circular polarization‐sensitive device is further realized () with a high CD (>0.9) response under the situation of intrinsic chirality. Such simultaneous performance of high PR, CD, and sharp resonance are related to the fact that optical absorption is primarily dominated by the grating walls while the offset of the geometry perturbation serves only to break the mirror symmetry and generate the CD response.

However, substantial emission attenuation at elevated temperatures poses a challenge to achieving high measurement precision. Herein, a facile solid‐state synthesis of efficient lanthanide‐doped fluoride double perovskites Cs2NaYF6, is reported presenting robust anti‐thermal quenching behavior while maintaining enhanced thermal sensitivity through partial substitution of Na+ with Li+. Li+ doping induces lattice contraction and increased stiffness, reducing phonon energy and suppressing electron–phonon coupling, thereby enhancing emission intensity and mitigating the thermal quenching of Er3+. Meanwhile, Li+‐induced local symmetry distortion around Er3+ leads to further Stark splitting of 2H11/2, promoting the thermally assisted population of green‐emitting levels, which retain 84% of their initial intensity at 523 K. In contrast, the red emission remains unaffected due to the large energy gap between adjacent levels. Consequently, both thermally coupled and non‐thermally coupled thermometric sensitivity are enhanced, with a maximum improvement of up to 6‐fold, leading to a substantial reduction in temperature uncertainty at high temperatures. Furthermore, the practical applicability of flexible polydimethylsiloxane‐based optical fiber and thin‐film temperature sensors is demonstrated. This provides insights into simultaneously optimizing the intensity and sensitivity of luminescent thermometers.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479074","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 work, the modular programming concept is introduced to develop the modular diffractive neural networks (MDNNs) using the cascaded metasurfaces where each metasurface enables respective functionalities while the cascaded metasurfaces possess additional functionalities. The MDNNs showcase great advantages in flexibility and reconfigurability for multitask functionalities. When working independently, two metasurface‐based modules can function as classifiers of handwritten letters and fashion products, respectively. When the two modules are assembled with different spatial orders, the additional functions of the handwritten digits classifier and imager can be obtained. Moreover, the MDNNs can be designed to mimic an architecture for high‐capacity encrypted communication. This flexible and multiplexed MDNNs framework shows great potential and paves the new way for all‐optical computation with multifunctional integration, massively parallel processing, and all‐optical information security.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"16 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479111","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}

Chiral molecules with stereoisomers, such as enantiomers, often exhibit distinct or even opposite biological activities. A critical step in drug development is the rapid and accurate differentiation of enantiomers. Due to its inherent chirality, circularly polarized light (CPL) is used commercially for chiral sensing and detection. Despite the progress, the weak interactions between CPL and chiral molecules make detection equipment extremely bulky and expensive. The construction of superchiral fields in nanophotonic devices can greatly enhance the interaction between chiral light and matter, offering the possibility of detecting chirality in a compact manner. Consequently, superchiral field has been intensively explored in the past decade. This review systematically summarizes the origin and developments of superchiral fields in different plasmonic and dielectric nanostructures, ranging from single nanoparticles to metamolecules and metasurfaces.

In contrast, solid‐state LiDAR is emerging as a viable alternative, offering enhanced performance and integration potential. Among the various techniques, frequency‐modulated continuous wave (FMCW) LiDAR stands out, especially for its suitability in velocity measurements and its compatibility with silicon‐based integration. This work introduces a new bridge‐balanced photodetector (Bridge‐BPD) for enhanced performance in FMCW LiDAR systems. By integrating optical couplers and Germanium‐Silicon photodetectors (Ge/Si PDs), this BPD improves the common‐mode rejection ratio (CMRR) by up to 12.8 dB compared to traditional methods, achieving 45.8 dB at a wavelength of 1550 nm. With FMCW LiDAR systems, high detection sensitivity is demonstrated and a detection probability of 90% at −98 dBm.

However, these strategies limit design flexibility and hinder efficient tunability. This study addresses these limitations by introducing a structurally decoupled approach to CPL production. The proposed multilayer composite system, composed entirely of achiral components, decouples chirality from luminescence and intrinsic structural elements. Specifically, achiral fluorescent films are integrated with twist‐stacked plasmonic polymer nanocomposite layers, achieving a high dissymmetry factor of 0.3 in the visible region. This innovative design allows independent control over CPL parameters, including wavelength, ellipticity, and handedness, through mechanical rotation or deformation. The decoupled architecture significantly enhances the material's design flexibility, scalability, and environmental stability. Furthermore, the resulting dynamic CPL material demonstrates practical applications in multi‐level, high‐capacity information encryption, offering promising prospects for advanced optical technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"48 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337515","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}

This paper presents an innovative approach that combines the radially self‐accelerating beams with orbital angular momentum (OAM) holography and 3D point cloud technology to enable fast and accurate 3D light‐field reconstruction from a single‐shot image. In experiments, the beams are independently convolved onto the point cloud, allowing each point to rotate around the optical axis during propagation. A light neural network is designed to deduce the relative heights of all points based on rotation properties and to reconstruct the 3D light field in 0.7 s with an accuracy of over 93%.

With the alteration of As4Qn functional molecules in identical Cd7I12Q polar metal inorganic framework, the NLO performance, birefringence and infrared transparency range of adducts can be tuned. Remarkably, Cd7I12Se·As4Se4 exhibits balanced comprehensive optical performances including a SHG effect of 1.3 × AgGaS2, a LDT of 11.2 × AgGaS2, an optical bandgap of 2.46 eV, birefringence of 0.045@2050nm/0.051@546nm and IR transparency range of 0.50–17.8 µm. The structure‐property relations analysis reveals that the macroscopic optical properties are dominated by the cavity‐filling molecular groups with varying polarizability and vibration frequency, which supports the tailoring effect of the functional molecular groups.
