An X‐ray imaging system based on the Tb<jats:sup>3+</jats:sup>‐doped nano‐GC scintillator delivers a record resolution of 28.7 lp mm<jats:sup>−1</jats:sup> at room temperature and 28.1 lp mm<jats:sup>−1</jats:sup> even at 500 °C, thanks to the excellent thermal stability, namely, the scintillator preserves the original XEL intensity up to 300 °C, and ≈73% at 500 °C.

VHOEs-based lightguides can suppress the eye-glow effect and use multiplexing to expand field of view (FOV) with good color performance. Along with the demonstration of good image quality, it makes VHOEs one of the best choices for couplers of EPE lightguide. This method utilizes the Model named “Volume Hologram being an Integrator of the Lights Emitted from Elementary Light Sources (VOHIL)” to derive an analytical solution for the wavelength-angular degeneracy properties of VHOEs, enabling the authors to calculate the peak wavelength distribution that passes through the lightguide. To prove the concept, by meticulously controlling the wavelength distribution and the full width at half maximum of the input light spectrum with a dispersion holographic optical element, a remarkable increase in efficiency is achieved. This approach yields an optical efficiency of 9% for the lightguide with a 30° FOV, representing a 5.63-fold improvement over conventional VHOE-based EPE lightguides. It is three times better than the best record of published efficiency in SRG-based EPE lightguides. This breakthrough has significant potential for advancing the development of high-performance, user-friendly near-eye glasses.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917891","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}

It is shown that the anisotropic nonlinear vortex beam generation can be achieved independent of the fork grating orientation with respect to the crystallographic orientation. Furthermore, 2D fork hologram is designed to generate multiple optical vortices having different topological charges with strong anisotropic responses.

Materials with exceptional photoluminescence (PL) properties generally possess highly efficient carrier radiative transitions. Investigating how to induce ML in these materials can provide new perspectives on the selection of ML materials. Here, a universal strategy for multicolor ML via radiative energy transfer by ultraviolet ML material Ca₉Al(PO₄)₇:Ce³⁺ (CAPC) is proposed. Multicolor ML can be regulated through the isomerization of energy acceptors. In CAPC@energy acceptor@polydimethylsiloxane composite system, the multicolor ML relies on a simple radiative energy transfer (reabsorption) mechanism, rather than the complex energy transfer between the excited states of ions. Using this strategy, certain highly efficient PL materials can develop ML, transitioning from nonexistent to present or from weak to strong. Additionally, the ML color can be tuned by adjusting the composition ratio of energy donor and acceptor. This work provides a simple, feasible, and versatile strategy for the selection and development of multicolor ML materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"14 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917437","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}

Herein, a series of efficient OHCHs based on inorganic building blocks [Cu₄Br₆]²⁻ clusters, designated as (TMAA)₂Cu₄Br₆, (EtTPPh)₂Cu₄Br₆, and (MtTBA)₂Cu₄Br₆ (TMAA = <i>N,N,N</i>-trimethyltrimethyl-1-adamantylammonium; EtTPPh = ethyltriphenylphosphonium; MtTBA = methyltri-n-butylammonium), are synthesized via a simple solution method. The three OHCHs exhibit broadband yellow emissions. Remarkably, the 0D (TMAA)₂Cu₄Br₆ shows a near-unity photoluminescence quantum yield, which can be attributed to the highly localized excitons and rigid environment. Impressively, it is demonstrated to show excellent scintillation performance with a high light yield of 46700 photon MeV⁻¹ and a low detection limit of 56.12 nGy_airs⁻¹.

Here, a robust strategy is developed through pressure-synergistic ligand engineering to achieve enhanced emission and remarkable piezochromism in the synthesized cadmium sulfide (CdS) nanocrystals (NCs) that exhibits both band-edge (BE) emission and strong defect emission. With increasing pressure, the CdS NCs experienced a piezochromism from orange emission to white emission. Note that by introducing additional ligand of cadmium oleate, a marked transition is achieved in emission color from orange to blue–violet with high color purity of 71.4% under high pressure. Furthermore, through the pressure-enhanced defect passivation with capping ligand, the CdS NCs realized a considerable BE emission enhancement, accompanied by the gradually decreased defect emission. In situ high-pressure experiments and first-principles calculations indicate that the interaction between ligand and CdS NCs is indeed enhanced under high pressure, thus facilitating the defects passivation and ultimately leading to the observed piezochromism and emission enhancement. This study endows high pressure as an efficient tool to enhance the surface defect passivation, paving the way for precise control over piezochromism and high-efficiency emission through materials design.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"32 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911837","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}

Contrary to the belief that dissipation disrupts Hermiticity and Zak phase quantization, theoretical and experimental evidence of their persistence in a non-Hermitian photonic waveguide array is presented. A three-layer Su-Schrieffer-Heeger (SSH) chain is demonstrated, which can be split into a Hermitian SSH subspace and a non-Hermitian ladder subspace through hidden symmetry. This division allows the SSH subspace to retain its topological properties, resulting in a quantized Zak phase and lossless topological bound states. Additionally, the non-Hermitian subspace supports coherent transport dynamics, with the phase and intensity of bound states fixed at two extreme SSH layers, confirming the presence of the Hermitian subspace. These findings enhance the understanding of the interplay between non-Hermiticity and topology and pave the way for coherent topological light transport.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"64 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911777","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 information is securely stored in the multiplexed field correlations which are inaccessible to a direct capture by a camera and retrieved only through rigorous statistical processing. The inherently incoherent nature of random waves makes this protocol crosstalk-free in principle and guarantees its high fidelity even in an extremely noisy environment.

Recently, integrated AOM is demonstrated with promising performance on various integrated piezoelectric materials. However, their optical conversion efficiencies remain significantly below unity. Achieving high efficiency necessitates strong mode-coupling over long interaction space, which requires strong confinement and minimizing losses for both acoustic and optical fields in integrated structures.

However, a single-layer planar metasurface, without the incorporation of chirality, can only achieve a maximum of three independent phase channels for single Jones matrix under either linear or circular polarization bases. Here, an effective strategy is proposed that utilizes dual Jones matrices in different polarization bases with a single-layer monoatomic metasurface, thus extending the number of independent phase channels to six. To encode six holographic images into these six phase channels, a three-step gradient descent algorithm is introduced. As a proof of principle, a metasurface consisting of arrays of monoatomic dielectric structure is designed and fabricated in each unit cell, which exhibits six independent holographic images in the far field. The demonstrated metasurface platform is expected to open up new possibilities for the development of optical devices for applications in high-capacity information storage, high-security encrypted communication, and high-solution optical displays.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"26 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911835","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}
