Perfect vortex beams (PVBs) carry valuable information in the intensity, phase, and polarization dimensions, offering powerful tools for optical communication, particle manipulation, and information encryption. Combining PVBs with a metasurface platform opens an avenue for multidimensional, high‐capacity, and secure optical encryption. However, precise control of the encoded dimensions and channels remains challenging. Here, we propose an optical encryption strategy based on a metasurface‐generated PVB array with four independent encryption dimensions and 441 parallel spatial channels. These dimensions, including PVB diameter, topological charge (TC) magnitude, TC sign, and polarization state, are mutually independent, significantly increasing the information capacity. In particular, the two phase‐related dimensions enhance encryption security because they cannot be directly measured by conventional CCDs. As a proof of concept, we develop a metasurface encryption system with high information capacity and improved security in the terahertz band. Four different QR codes are encrypted in a single metasurface device and can be decrypted only with the correct keys. By using each PVB as a basic information unit, the system becomes more controllable and robust. This work provides a strategy for high‐capacity and secure optical encryption, paving the way toward multidimensional photonic devices for encryption, data storage, and optical communication.

Implementing light polarization control has enabled the realization of numerous fascinating optical phenomena and functionalities in both scientific and industrial applications. However, achieving precise and deterministic manipulation of light polarization in shorter wavelength, e.g., deep ultraviolet (DUV) band (λ < 280 nm) remains challenging. Herein, we demonstrate, for the first time, electrode‐engineered polarization control of DUV emission directly from a light emitter, without involving bulky external optics or complex metasurface or plasmonic architectures. Simply by strategically engineering the p‐type electrode geometry from circular, micro‐ring to narrow‐ring configurations, the relative contributions of transverse‐magnetic (TM) and transverse‐electric (TE) emission can be systematically controlled, yielding well‐separated TM to TE intensity ratios of 0.36, 0.54, and 0.77, respectively. Strikingly, their −3 dB bandwidths are 261, 298, and 300 MHz, respectively, with corresponding high‐speed data rates of 2.49, 2.63, and 2.87 Gbps can be achieved. Building upon this controllable polarization and modulation landscape, we further demonstrate polarization‐assisted multiplexing and physical‐layer secure optical communication by leveraging device‐specific polarization states as intrinsic optical fingerprints. These results establish a feasible and scalable approach toward the direct control over the DUV‐light polarization for high‐speed and secure ultraviolet photonic systems.

Bound states in the continuum (BICs) are polarization singularities in momentum space whose topological charges (TCs) govern advanced light‐matter interactions. While lattice symmetry protects the existence of robust BICs at the Γ‐point (SP‐BICs), it also restricts their TCs to low‐order values. Achieving high‐order TCs in common crystal lattices, such as ‐symmetric systems, has therefore remained an open question. Here, we systematically demonstrate that high‐order TCs that surpass fundamental symmetry bounds can be created through the rich dynamics of a parameter‐driven merging process of off‐Γ BICs. We introduce a unified geometric framework based on the interplay between Fabry–Pérot interference and guided resonances, which uncovers different types of merging BICs dynamics, including near‐isotropic, anisotropic, and cross‐merging. Leveraging this mechanism, we realize unconventional TCs of up to at either a symmetry‐protected BIC or a degeneracy point in a simple ‐symmetric photonic crystal slab. We further show that this high‐order topology enables the generation of high‐quality Bessel OAM beams, providing a physically transparent route toward engineering high‐order topological photonics.

Wavefront shaping enables near-complete optical extinction by nanoscatterers separated from a planar reflector. Time-reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub-wavelength nanoparticle clusters, offering a promising route to efficient in- and out-coupling in nanophotonic devices.
