However, in most existing approaches, the physical connection between device tuning parameters and underlying resonant modes remains unclear. Here, a new theoretical analysis method combining the electromagnetic response Jacobian with the Friedrichs–Lee self‐energy model is proposed. The method formulates amplitude–phase decoupling as a local parameter–response problem and reveals the mechanism of amplitude–phase coupling at the resonant modes level. Based on this model, a structured‐bath design is established as a concrete approach to realizing amplitude–phase decoupling. The mechanism is systematically validated and implemented in a reconfigurable meta‐atom. Two independent electrical tuning parameters selectively regulate different modal responses, enabling continuous reflection‐amplitude tuning from −10 dB to nearly 0 dB while maintaining broad phase coverage. Furthermore, a programmable metasurface is constructed based on the experimentally measured accessible complex‐response state cloud. A region‐adaptive mapping method is introduced to map the ideal complex‐amplitude distribution onto experimentally realizable states. Dynamic complex‐amplitude holography is subsequently demonstrated, validating the decoupling mechanism at the programmable wavefront level. This work provides a physically informed and practical design strategy for amplitude–phase decoupling in reconfigurable metasurfaces, supporting the advancement of dynamic complex‐amplitude wavefront control and programmable metasurface technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"13 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172606","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, free‐space OVIs are hindered by cumbersome coaxial alignment, while existing all‐fiber architectures rely heavily on polarization controllers to maintain high‐purity vortex states, severely limiting their plug‐and‐play capability and engineering reliability. Here, we propose a polarization‐controller‐free, plug‐and‐play all‐fiber OVI. At the hardware level, a mode‐selective coupler is utilized to excite higher‐order modes within the fiber and accomplish interference, thereby eliminating free‐space coaxial alignment. At the physical mechanism and software demodulation levels, this paper reveals the “intensity redistribution” phenomenon and the trajectory degradation mechanism of the corresponding azimuthal complex spectrum in the complex plane during interference involving impurity modes, and accordingly proposes a generalized azimuthal complex spectrum demodulation algorithm. Crucially, our results demonstrate that even under a marginal 2% impurity, the proposed algorithm enhances phase measurement accuracy by nearly two orders of magnitude compared to standard methods. As a proof‐of‐concept, the system achieves a normalized temperature sensitivity of 36.53 rad/() in temperature sensing without requiring manual polarization tuning. This work innovatively shifts the hardware calibration burden to the underlying analytical algorithm, significantly enhancing OVI feasibility for on‐site and industrial deployment.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"167 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172602","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}

While suppressing speckle noise is challenging, doing so while pushing diffraction efficiency to its near‐unity physical limit represents an even greater barrier. Here, we address this efficiency‐fidelity trade‐off by integrating a dual‐layer metasurface architecture with a gradient‐based progressive‐efficiency optimization (GPEO) strategy, unlocking a solution space where near‐unity efficiency coexists with pristine image quality. We demonstrate that this configuration effectively eliminates both stochastic speckle and deterministic singularity artifacts, achieving a speckle contrast as low as 0.013 (simulation) and 0.075 (experiment). Remarkably, this high‐fidelity reconstruction is realized alongside record‐breaking diffraction efficiencies of 97% in simulation and 95% in experiment, pushing the system performance to its theoretical ceiling. This work overcomes a key bottleneck in holography, establishing a new benchmark for high‐performance systems and paving the way for their application in advanced display technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173001","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}

Among them, OIHMHs with non‐centrosymmetric structures are particularly attractive for their polar characteristics. Disulfide‐containing A‐site organic cations represent promising symmetry‐directing units owing to their dynamic conformation and potential axial chirality. However, their intrinsic flexibility often leads to disorder or racemization, weakening their capability in directing stable non‐centrosymmetric OIHMHs. Herein, we rationally developed a series of OIHMHs featuring rotatable disulfide bonds and uncovered a symmetry‐regulation mechanism in which dynamically adaptive disulfide‐containing cations actively promote asymmetric and non‐centrosymmetric arrangements of inorganic metal‐halide polyhedra. The formamidine disulfide dication (FDD 2+ ), with adaptive conformational adjustment driven by dihedral‐angle rotation, enables divergent structural evolution through adaptive coupling with ns 2 metal centers of different electronic character. The resulting four non‐centrosymmetric OIHMHs exhibit second harmonic generation performances several times those of the benchmark KH 2 PO 4 , promising their nonlinear optical photonic applications. This work establishes dynamic‐bond‐containing cations as effective symmetry regulators in OIHMHs for the construction of non‐centrosymmetric and polar hybrid materials with advanced optoelectronic functionalities.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"53 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172604","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}

Nonvolatile optical phase‐change materials (PCMs) enable set‐and‐hold spectral correction without static holding power, yet integrated PCM platforms operating beyond 3 µm remain largely unexplored. Here, an Sb 2 Se 3 /silicon‐on‐sapphire trimming platform operating near 3.2 µm is demonstrated in three representative sensing‐oriented architectures: Mach–Zehnder interferometers (MZIs), microring resonators (MRRs), and Bragg gratings. Guided by optical and thermal design, this platform enables low‐loss phase and spectral trimming. Ex situ hot‐plate crystallization establishes the amorphous‐to‐crystalline end‐state trimming range, whereas integrated microheaters provide in situ multilevel trimming through progressive electrically driven crystallization. The PCM‐loaded hybrid waveguide used in the MZI and MRR yields a π‐phase‐shift length of 48 µm, while the Bragg device exhibits an 18 nm expansion of the 3 dB stopband bandwidth. To the best of our knowledge, this is the first experimental demonstration beyond 3 µm of a nonvolatile PCM‐integrated trimming platform spanning interferometric, resonant, and Bragg architectures. These results establish a practical route toward zero‐static‐power calibration and nonvolatile spectral correction in integrated mid‐IR photonics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"5 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172605","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}
