We introduce a cost‐effective, high‐performance Handheld Embedded Laser‐diode Illumination Optoacoustic System (HELIOS) based on a spherical array probe incorporating a compact illumination source located in close proximity to the imaged object. High performance drivers have been designed to produce 1.8 mJ energy pulses at 915 nm wavelength, sufficient for rendering entire ≈1 cm3 image volumes with high spatial and temporal resolution. The fast imaging performance is further facilitated by high‐speed acquisition electronics capable of simultaneous sampling of all 256 transducer channels, thus enabling volumetric imaging at up to 400 Hz frame rate corresponding to pulse repetition frequency of the laser diodes. HELIOS attains image quality and performance metrics on par with those achieved with solid state laser sources. We then demonstrate real‐time volumetric angiography of human fingers and palm in a freehand mode, perform large‐scale volumetric compounding of vascular structures from the time‐lapse 3D data, and visualize vessel perfusion and pulsation with the system. The work represents a major leap toward the translation of optoacoustics into point‐of‐care diagnostics and enabling its dissemination in resource‐limited settings.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"12 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715369","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 key function of polarization multiplexing devices is to separate and convert the polarization states of light waves using devices such as polarization beam splitters (PBS) and polarization rotators (PR). This paper reviews various design structures for polarization multiplexers, such as directional coupler (DC) structures, multimode interference (MMI) structures, Y‐branch structures, and auxiliary structures like photonic crystals (PC), hybrid plasmonic waveguides (HPW), subwavelength gratings (SWG), and slot waveguides, as well as the applications of various materials, such as silicon, silicon nitride, lithium niobate, and compounds. The paper emphasizes the application of inverse design techniques in polarization multiplexer devices, particularly in improving the design efficiency and performance of devices through the combination of deep learning and optimization algorithms. With the continuous advancement of technology, polarization multiplexing devices will become more compact and efficient, and through hybrid multiplexing technology, combined with wavelength division multiplexing (WDM) and mode division multiplexing (MDM), communication capacity will be significantly increased. Although current devices still face challenges in terms of performance and manufacturing processes, they have great application potential in the future in optical interconnection chips, quantum computing, and biological detection.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"5 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715371","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}

Classic dispersion design methods for metasurfaces, including forward and inverse methods, cannot simultaneously achieve high interpretability from theoretical equations and optimizability via feedback of the output field. In this article, a semi‐inverse design method based on phase matching is proposed. This method achieves dispersion design by matching theoretical phase and phase responses of meta‐atoms, while iteratively adjusting the physical parameters in theoretical equations based on the far‐field energy distribution. The working parameters of the metasurface and the combination of meta‐atoms (instead of the shapes of the meta‐atoms), are optimized iteratively to make the output field match the design. Using the proposed method, three broadband devices are presented. The first is an achromatic metalens working in 850–1800 nm, achieving high efficiency greater than 70% within 1100–1800 nm. The second is a spectral router working in 850–1550 nm with an average efficiency of 75%. The third is a metalens with abnormal dispersion working in 1200–1800 nm with ≈80% diffraction efficiency. The proposed method is versatile and can be applied in the field of applied optics such as achromatic imaging and spectral routing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"129 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715370","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 optical properties of metal halides are closely related to their crystal structures, and the diversity of crystal structures is a key factor in achieving efficient tunable emission. Herein, four different Sb3+‐doped In3+‐based metal halides of 3D Cs2KInCl6:Sb3+, 1D (DFEA)2KInCl6:Sb3+ and (DFEA)2(NH4)InCl6:Sb3+, and 0D (DFEA)3InCl6:Sb3+ (DFEA = 2, 2‐difluoroethylamine) are reported, all of which exhibit different crystal structures, resulting in efficient tunable emission bands shift from 495 to 605 nm. It is found that the larger [SbCl6]3− distortion is the reason for the redshift of the emission band, which allows to stepwise unlock the full‐spectrum emission with ultra‐high luminescence efficiency. Compared all‐inorganic Cs2KInCl6:Sb3+, the other three Sb3+‐doped hybrid In3+‐based metal halides exhibit abnormal anti‐thermal quenching behavior, which should be attributed to the participation of shallow trapped states caused by the structural defects. The tunable emission characteristics of Sb3+‐doped metal halides make them show great application potential in solid‐state lighting, optical anti‐counterfeiting, and information encryption.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"92 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715367","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 their versatility, achieving self‐starting mode‐locking remains a significant challenge. In this study, the critical role of the dissipative Faraday instability (DFI) in facilitating the self‐starting process of Mos is unveiled, where the DFI triggers the symmetry breaking of the homogeneous solution to overcome the initiation barriers. A panoramic view of several distinct operational regimes with distinct DFI patterns is provided, namely the non‐self‐starting states, the irregular patterns, the harmonic mode locking regime, the stable single pulse and the stable multi pulse regime. For the latest case, the origins of randomness in these pulse sequences through analyzing the causality between the timing of the random pulses and the initial seeding conditions are uncovered. Building upon these findings, the novel time‐injection locking technique is proposed to customize the temporal locations of the pulses as well as the pattern timing in MOs, thus demonstrating its potential for applications in all‐optical data storage and tunable ultrashort pulse sources.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"12 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710750","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 study shows, by detailed spectroscopic measurements in CsBr0.9Cl0.1:Eu2+, that exciton lifetime can be controlled by four orders of magnitude between Eu3+ and Eu2+ ions, with 35 ms deriving from parity‐forbidden 5D3→7Fj (j = 1–5) transitions of Eu3+ to 639 ns belonging to the dipole‐allowed 5d→4f transition of Eu2+. The excited‐state lifetime of Eu3+ can be kept for two weeks at room temperature, while maintaining high photoluminescence quantum yield of 93.4% and good thermal stability (85%@433 K). Steady‐state and transient‐state spectroscopies reveal blue emissions from the high‐energy 5D3 excited state of Eu3+ are strongly limited and quenched by oxygen molecules. Electron paramagnetic resonance spectroscopy and theoretical calculations confirm the 4f electrons are highly delocalized due to significantly reduced electron and hole wavefunction overlap, leading to singlet‐oxygen generation via electron transfer.
