Fluorescent diarylethene (DAE) photoswitches, with exceptional reversibility, thermal stability, fatigue resistance, and tunable photochromism, enable this approach by reversible switching between fluorescent “on” and dark “off” states, allowing neighboring molecules within the diffraction limit to be distinguished. Fluorescent DAE derivatives have recently garnered increasing attention as fluorescent labels for SRI applications, offering decisive advantages over conventional photoswitches. Despite considerable progress, a systematic review specifically addressing the application of DAEs in SRI remains absent. Herein, we present a comprehensive survey of fluorescent DAE photoswitches for SRI, centering on molecular design strategies and recent advances. We categorize these systems into four classes based on their activation modes and driving mechanisms: “turn‐on” fluorescent DAEs, “turn‐off” fluorescent DAEs, polymeric fluorescent DAEs, and visible‐light‐driven DAEs. For each category, we highlight representative structures, key design rationales, and imaging performance benchmarks. We conclude by identifying current challenges and outlining future perspectives, aiming to guide the rational development of next‐generation fluorescent DAE photoswitches for advanced super‐resolution bioimaging.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208492","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}

Its chemical stability, strong piezoelectric properties, and biocompatibility have turned GaN into a crucial candidate for next‐generation microelectromechanical systems (MEMS), including sensors, resonators, and energy harvesters operating in harsh environments. However, GaN's transition from planar devices to 3D MEMS structures is limited by its hardness, brittleness, and chemical inertness. Conventional fabrication methods induce heat‐affected zones, lattice damage, and micro‐cracks, significantly reducing device yield and performance. This review presents a comprehensive analysis of ultrafast laser micro/nano processing as a transformative, non‐contact manufacturing paradigm to overcome these limitations. We first elucidate the fundamental mechanisms of laser–material interactions, distinguishing between picosecond (ps) and femtosecond (fs) regimes, with attention to non‐linear absorption, ionization dynamics, and non‐thermal ablation enabling submicron resolution with minimal collateral damage. We investigate laser methodologies including maskless direct writing, laser lift‐off (LLO), and laser‐induced periodic surface structures (LIPSS), highlighting their integration into high‐performance GaN MEMS devices for enhanced sensitivity. We explore hybrid integration with complementary metal‐oxide‐semiconductor (CMOS) technology and artificial intelligence (AI)‐driven optimization to address throughput challenges, offering pathways toward wafer‐scale manufacturing of next‐generation GaN MEMS.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"34 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208463","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}

Here, we propose and experimentally demonstrate a cross‐scale integrated photonic convolver (CSIPC) that enables cross‐scale feature extraction through a single training process. Implemented on a hierarchically coupled finite‐impulse‐response (FIR) photonic chip, the CSIPC exploits the propagation of conjugate‐symmetric interference‐weight relations through the coupling network, together with the spatiotemporal interleaving induced by serial‐to‐parallel conversion. A single set of trained chip weights can be mapped at different output ports into a family of equivalent convolution kernels with distinct effective tap numbers and temporal intervals. By selecting the output port and tuning the input symbol rate, 2 × 4, 2 × 2, and 2 × 1 two‐dimensional convolution kernels can be realized on the same chip. We experimentally validate multifunctional cross‐scale image feature extraction and achieve a maximum single‐mode equivalent computing throughput of 0.276 TOPS. These results provide a route toward cross‐scale photonic convolution using a single device and a single training process, while improving functional integration density and enabling the reuse of trained weights and hardware resources.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"30 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208462","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}

As a special type of 3D solitons, 3D breathers possess abundant evolutionary characteristics, yet the mode‐resolved dynamics remain unexplored. Here, two distinct types of 3D breathers are experimentally realized in an STML fiber laser, and the real‐time dynamical evolution of individual transverse modes is captured via mode‐resolved measurement. The two breathers exhibit markedly different energy exchange mechanisms: one involves energy exchange among transverse modes (asynchronous transverse modal energy evolution), while the other features energy exchange among spectral components (asynchronous energy evolution of spectral components). Due to energy exchange among spectral components and bandwidth disparities among spectral peaks, energy modulation depth is remarkably lower than spectral intensity modulation depth. Numerical simulations qualitatively reproduce both experimentally observed 3D breathers. Linear mode coupling (LMC) dominates synchronous transverse modal energy evolution, while asynchronous transverse modal energy evolution relies on both LMC and propagation effects (including intermodal gain competition and nonlinear effects such as intermodal four‐wave mixing) in Yb‐doped fiber. This work reveals individual modal dynamics and their complex interactions during 3D soliton breathing, deepening understanding of intricate spatiotemporal dynamics in STML fiber lasers.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"46 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208460","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 remains hindered by severe twin‐image artifacts due to the absence of sensor‐plane phase information. Iterative approaches are sensitive to noise and prone to local minima, while existing learning‐based approaches rarely exploit sensor‐plane phase as a physically meaningful initialization and insufficiently integrate diffraction physics with complex‐domain learning. Here, we propose a dual‐plane‐driven complex‐valued cascaded neural network (DP‐CVNN) for phase retrieval in inline holography. The framework combines a front‐end real‐valued network for sensor‐plane phase estimation with a back‐end complex‐valued neural network for diffraction propagation learning, thereby enabling physically meaningful reconstruction from single‐shot inline holograms. By jointly constraining sensor‐plane and object‐plane phases through diffraction‐consistent supervision, the proposed framework effectively bridges data‐driven holographic reconstruction with physics‐consistent optical modeling in the complex domain, thereby reducing sensitivity to noise‐contaminated intensity measurements. Simulations and experiments on diverse phase‐dominant samples demonstrate effective suppression of twin‐image artifacts, achieving favorable reconstruction fidelity and noise robustness compared with representative conventional and learning‐based methods. Our findings further validate the critical role of sensor‐plane phase initialization, as well as its potential to benefit conventional phase retrieval algorithms.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"21 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208465","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}

Replacing Cl with I dramatically increases the photoluminescence quantum yield (from 20.2% to 84.3%) but drastically reduces humidity resistance at 90% relative humidity (RH) (from ∼51 h for the bromide to &lt;14 min for the iodide). Remarkably, the thermal stability trend is reversed: the iodide shows enhanced emission at 430 K, whereas the chloride is heavily quenched. This paradoxical thermal robustness of the iodide, despite its large electron–phonon coupling (Huang–Rhys factor S = 4.43), can be rationalized by the energy‐gap law for multiphonon relaxation. Raman spectroscopy reveals an exceptionally low Mn–I phonon frequency (111 cm <jats:sup>−1</jats:sup> ), which exponentially suppresses multiphonon non‐radiative decay, effectively closing the non‐radiative channel even under strong coupling. Exploiting these orthogonal stabilities, we construct a dual‐stimulus encryption device responsive to specific humidity‐heat sequences.

A 2D metasurface‐3D metastructure composite design is proposed to construct a Resonator‐Gyroid Synergistic Metamaterial (R‐GSM). This structure integrates a 2D indium tin oxide (ITO) array with a 3D carbon‐based gradient Gyroid network. By coupling the low‐frequency resonance of the 2D units with the high‐frequency impedance matching and multiple scattering of the 3D structure, a continuous energy dissipation path is established. The results indicate that the R‐GSM mitigates the low‐frequency thickness constraints dictated by the traditional quarter‐wavelength resonance model. A prototype with a thickness of 15 mm (0.25 g/cm <jats:sup>2</jats:sup> ) demonstrates ultra‐broadband absorption from 2.4 to 40.0 GHz. Furthermore, by scaling the thickness to 20 mm (0.32 g/cm <jats:sup>2</jats:sup> ), it achieves a broad absorption bandwidth of 182.8% (1.8–40.0 GHz, reflection loss &lt; −10 dB), approaching theoretical limits. It also exhibits excellent wide‐angle incidence stability and polarization insensitivity, with measurements closely matching multiphysics simulations. Radar cross‐section (RCS) evaluations demonstrate that this structure can be conformally integrated with curved surfaces, significantly reducing the scattering signatures of targets. The multi‐dimensional heterogeneous integration strategy provides a reliable design approach for developing lightweight and ultra‐broadband electromagnetic stealth structures.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"9 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208467","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}
