However, most existing LC‐based holographic encryption schemes rely on conventional multiplexing strategies with limited design freedom and weak interlayer collaboration, hindering the further advancement of holography toward greater information capacity and higher security. Herein, we propose an interlayer‐correlated LC planar platform, where the phase profiles of three LC devices are jointly optimized to generate three near‐field display patterns and six far‐field holographic images. More importantly, the scalability of this platform is validated experimentally, yielding 24 distinct images by integrating conventional multiplexing techniques. Furthermore, 39 high‐fidelity images are numerically achieved by increasing the number of reconstruction distances and exploiting the non‐commutative property of Jones matrix multiplication. Based on the proposed multi‐channel LC platform, we further develop a nested optical encryption scheme with ultra‐high security. Revelation of the final encrypted information requires joint decryption by three authorized technicians across multiple critical dimensions. Consequently, this work establishes a scalable LC platform for high‐density data storage, demonstrating great application potential in information display, identity authentication, and optical encryption.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"8 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768366","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}

Cadmium‐free ZnSeTe/ZnS CQDs offer a viable alternative, but developing laser platforms that combine ambient operational stability with low‐speckle imaging remains challenging. Here, we report ambient‐stabilized pure‐blue microlasers based on self‐assembled ZnSeTe/ZnS CQD supraparticles (SPs) conformally encapsulated with an ultrathin Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> shell.

Deposited by atomic layer deposition (ALD), the Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> shell suppresses oxygen ingress. As a result, the operational half‐life of the SP microlasers increases by more than two orders of magnitude, while the mean lasing threshold decreases from 36 µJ cm <jats:sup>−</jats:sup> <jats:sup>2</jats:sup> for the pristine SPs to 26 µJ cm <jats:sup>−</jats:sup> <jats:sup>2</jats:sup> for the 15 nm Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> ‐coated SPs.

This coexistence of narrow‐line and broadband emissions provides multiple complementary readout channels based on spectral shifts and luminescence intensity ratios, indicating the potential of this phosphor for multimodal pressure readout under compression. Ab initio calculations of pressure dependent excited states produce configurational coordinate diagrams that clearly reveal how compression perturbs excited state energies and alters equilibrium Cr─O bond lengths. These insights rationalize the opposite pressure shifts of narrow line and broadband emissions and their intensity variations. Crucially, a correlation between excitation‐induced bond length changes and pressure dependent spectral shifts was identified, showing that direction and magnitude of structural response upon excitation govern high pressure luminescence.

Leveraging its capability for flexible full‐space electromagnetic manipulation, the transmission‐reflection integrated programmable metasurface (TRIPM) emerges as a key enabling technology for this goal. However, existing designs are often limited to single‐polarized beam control, which poses a risk of communication interruption for heterogeneous aerial targets due to polarization mismatch. To address this limitation, we propose a novel programmable metasurface that integrates multiple electromagnetic‐manipulation functions, including transmission‐reflection switching, full‐space beam scanning, and multi‐polarized conversion, into a single aperture. The incident radio‐frequency energy can be manipulated by the metasurface to provide stable linearly polarized signal coverage for ground Internet‐of‐Things devices in the reflection half‐space, while simultaneously achieving adaptive switching among linear, left‐hand circular, and right‐hand circular polarizations in the transmission half‐space to meet the real‐time communication demands of diverse air and space targets. Experimental results demonstrate that the proposed TRIPM platform possesses flexible, multi‐degree‐of‐freedom electromagnetic‐manipulation capabilities, enabling dynamic coverage of linearly and dual‐circularly polarized signals. The proposed TRIPM provides a crucial hardware foundation for next‐generation intelligent and integrated space‐air‐ground networks.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"35 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768819","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}

To achieve spin‐decoupled wavefront control in PB metasurfaces, current approaches introduce additional resonant phase, propagation phase, or exceptional topological phase; however, these strategies not only complicate the design but also inevitably lead to severe amplitude non‐uniformity across different meta‐atoms. Herein, we propose an alternative strategy by encoding the required dual‐phase information into an amplitude‐phase dataset. Utilizing double‐layer C‐shaped split‐ring resonators as meta‐atoms, two terahertz metasurfaces were designed and characterized for experimental validation. The first metasurface operates at 0.7 THz, reconstructing holographic “L” and “R” images under left‐ and right‐handed circularly polarized (LCP/RCP) illumination, respectively. The second metasurface generates holographic images of Arabic numerals 1–4 across four distinct channels (LCP and RCP incidence at 0.55 and 0.85 THz). This methodology significantly enhances polarization‐frequency multiplexing capacity, which may boost optical encryption, holography, and communications from the bottom up.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"16 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768375","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 core idea is to reorganize the original 1D 2 <jats:italic>f</jats:italic> signals into 2D HSMs, thereby reformulating conventional waveform denoising as a self‐supervised structured reconstruction task. In this way, weak signals can be recovered from the intrinsic structural correlations of the data itself rather than from externally constructed pure labels.
