Construction of a desired phase profile at will can be realized through spatially varying sub‐wavelength‐scale nanoantennas, underpinning diverse ultrathin optical devices, including anomalous beam deflectors, metalenses, metahologram, polarizers, and vortex beam generators .

and vortex beam generators. [10][11][12] In particular, phase-gradient metasurfaces can cumulatively produce blazed phase profiles for essential far-field interference to redirect the incident wave to the anticipated direction under normal incidences. [13][14][15] However, these approaches suffer from the intrinsic restriction owing to the limited number of elements in a supercell which can fit into each periodically repeated units to discretely map the desired phase profiles. Apparently, phase-gradient metasurfaces inevitably deteriorate beam steering performance at large bending angles with significantly degraded efficiencies. [13][14][15] To tackle this challenge, high diffraction metagratings capable of ultrahigh angle beam bending were proposed. [16][17][18][19][20][21][22][23][24][25][26][27][28] Breaking the symmetry of the illumination condition of the metagrating can allow high diffractions, funneling light into the desired diffraction order with high efficiencies at oblique incidences. [16][17][18][19][20][21][22][23] Based on this scheme, high diffractions in either reflection mode using metallic metagratings [16][17][18][19] or in the transmission mode using all-dielectric metagtratings [20][21][22][23] have been achieved. Alternatively, at symmetric illumination condition, asymmetric building blocks with multiple separate inclusions of different dimensions or geometries were usually considered as a necessity to generate far-field interference for directional scattering patterns without adversely affecting each other's mode. Engineering the directional scattering patterns of periodically repeated building blocks of the metagrating demonstrates the potential to channel the incident light into desired diffraction orders at will. [24][25][26][27][28] In particular, high-index all-dielectric nanoantennas featured with geometry-tunable multiple Mie resonances for associated novel effects [26] open a new route to selectively enhance/suppress a single diffraction order in both reflection and transmission modes. However, the innate frequency divergence of multiple separate inclusions hinders the high diffraction efficiency from wide frequency and angle range, which are highly desirable for various beam steering applications. Moreover, the diffraction efficiency is strongly dependent on the separation between such asymmetric nanoantennas, which exacerbates challenges for stringent fabrication precision.Here, we propose a kind of kissing-dimer metagratings (Figure 1a), which can steer the illumination light Transcending the common perceptions of phase-gradient metasurfaces, metagratings emerge as a new paradigm for wavefront manipulation directly on the desired diffraction order with ultrahigh deflection angles. However, previous metagratings rely on directional scattering caused by multiresonant interference between multiple separate inclusions, of which the high diffraction efficiencies are only optimized with limited bandwidth and incident angle tolerance. Here, a kind of asymmetric kissing-dimer metagrating...

Phase, polarization, amplitude, and frequency represent the basic dimensions of light, playing crucial roles for both fundamental light-material interactions and all major optical applications. Metasurfaces have emerged as a compact platform to manipulate these knobs, but previous metasurfaces have limited flexibility to simultaneous control them. A multi-freedom metasurface that can simultaneously and independently modulate phase, polarization, and amplitude in an analytical form is introduced, and frequency multiplexing is further realized by a k-space engineering technique. The multi-freedom metasurface seamlessly combines geometric Pancharatnam-Berry phase and detour phase, both of which are frequency independent. As a result, it allows complex-amplitude vectorial hologram at various frequencies based on the same design strategy, without sophisticated nanostructure searching of massive geometric parameters. Based on this principle, full-color complexamplitude vectorial meta-holograms in the visible are experimentally demonstrated with a metal-insulator-metal architecture, unlocking the longsought full potential of advanced light field manipulation through ultrathin metasurfaces.functional layers, emerge as a desirable platform to manipulate the light field at will with large control and flexibility. [3][4][5][6][7] Exciting applications have already been demonstrated on the metasurface platform, including flat diffractive and polarization optical components, much more compact and lightweight than conventional bulky counterparts. By engineering the scattering properties of the individual metaelements constituting the metasurface to mold the geometric phase, resonant phase or propagation phase, we are able to control phase, [8,9] amplitude, [10,11] polarization, [12,13] or frequency [14][15][16] of light, leading to high-efficiency metalenses, [9] high-fidelity holograms, [8] broadband polarization components, [12,17] and highperformance biosensors. [15] However, these ultrathin components tend to focus on single-dimensional light manipulation, controlling either the local phase, or amplitude, or polarization, or frequency, at a time, inherently limiting potential opportunities. For example, metasurface holograms and metalenses based on resonant phase and propagation phase are typically limited to a narrow range of frequencies. [18,19] Geometric Pancharatnam-Berry (P-B) phase metasurfaces operate over broader bandwidths, but they are restricted to circular polarization only. [8] To improve the performance and enrich the functionality of metasurfaces for a broader range of applications, independent

Optical metasurfaces enable novel ways to locally manipulate light's amplitude, phase, and polarization, underpinning a newly viable technology for applications, such as high‐density optical storage, holography, and displays. Here, a high‐security‐level platform enabled by centimeter‐scale plasmonic metasurfaces with full‐color, high‐purity, and enhanced‐information‐capacity properties is proposed. Multiple types of independent information can be embedded into a single metamark using full parameters of light, including amplitude, phase, and polarization. Under incoherent white light, the metamark appears as a polarization‐ and angle‐encoded full‐color image with flexibly controlled hue, saturation, and brightness, while switching to multiwavelength holograms under coherent laser illumination. More importantly, for actual applications, the extremely shallow functional layer makes such centimeter‐scale plasmonic metamarks suitable for cost‐effective mass production processes. Considering these superior performances of the presented multifunctional plasmonic metasurfaces, this work may find wide applications in anticounterfeiting, information security, high‐density optical storage, and so forth.
