“…One direct application of the proposed Malus metasurfaces is information multiplexing, which can provide a completely new information channel with phase manipulation in the far field in addition to the information channel with amplitude manipulation at the nanostructure surface. We note that there have been recent reports on the combination of nanoprinting and holography 13,[31][32][33][34][35][36][37][38][39] ; however, our concept does not conflict with their schemes, and it provides an extra degree of freedom to further increase the information capacity. Furthermore, it is promising to merge wavelength multiplexing 46 with the proposed Malus metasurfaces to simultaneously generate a near-field colorful pattern and far-field holographic images.…”

“…The above multiplexed metasurfaces have been applied in many fields, such as multichannel holograms 28 , color holograms 29 , and polarization cameras 30 . In addition, a variety of schemes have been proposed to simultaneously realize amplitude and phase control (i.e., complex amplitude modulation), implemented by utilizing the coupling effect between two nanostructures 31 , changing the geometry dimensions of nanostructures to form a set of wave plates with varied phase difference 32 , interleaving multiple metasurfaces in plane [33][34][35][36] , stacking metasurfaces in space [37][38][39] , etc. However, both the polarization multiplexing and complex amplitude modulation mentioned above require complex nanostructure design or sacrifice of some control of the optical transmission matrix, which therefore burdens the fabrication process or decreases the information density of each image channel.…”

Malus-metasurface-assisted polarization multiplexing

Polarization optics plays a pivotal role in diffractive, refractive, and emerging flat optics, and has been widely employed in contemporary optical industries and daily life. Advanced polarization manipulation leads to robust control of the polarization direction of light. Nevertheless, polarization control has been studied largely independent of the phase or intensity of light. Here, we propose and experimentally validate a Malus-metasurface-assisted paradigm to enable simultaneous and independent control of the intensity and phase properties of light simply by polarization modulation. The orientation degeneracy of the classical Malus's law implies a new degree of freedom and enables us to establish a one-to-many mapping strategy for designing anisotropic plasmonic nanostructures to engineer the Pancharatnam-Berry phase profile, while keeping the continuous intensity modulation unchanged. The proposed Malus metadevice can thus generate a near-field greyscale pattern, and project an independent far-field holographic image using an ultrathin and single-sized metasurface. This concept opens up distinct dimensions for conventional polarization optics, which allows one to merge the functionality of phase manipulation into an amplitudemanipulation-assisted optical component to form a multifunctional nano-optical device without increasing the complexity of the nanostructures. It can empower advanced applications in information multiplexing and encryption, anti-counterfeiting, dual-channel display for virtual/augmented reality, and many other related fields.

“…In particular, optical metasystems consisting of two or more metasurfaces have mainly been exploited to produce compact devices acting as retroreflectors, [ 22 ] spectrometers, [ 23 ] hyperspectral imagers, [ 24 ] and optical planar cameras. [ 25 ] While the aforementioned metasurfaces were developed to serve single functions, multifunctional metasurfaces that can perform multiple tasks have attracted considerable interest owing to their potential use as multifocal or achromatic lenses, [ 26–28 ] metadevices serving distinct wave‐manipulation functionalities, [ 29–35 ] imaging systems, [ 36–38 ] nonlinear coding metasurfaces, [ 39–41 ] and vector vortex beam (VVB) generators. [ 42,43 ] For instance, metasurfaces in the visible or millimeter‐wave regime have been applied to implement VVB generators leading to vortex beams with different topological charges, with the assistance of unit cells consisting of multiple nanoblocks/layers with different geometrical parameters.…”

Multifunctional metasurfaces, which are planar devices featuring diverse functionalities, have attracted tremendous attention as they enable highly dense integration and miniaturization of photonic devices. Previous approaches based on spatial/spectral multiplexing of meta‐atoms on single metasurfaces are supposed to be inevitably limited in their functional diversity. An additional degree of freedom for design, achieved by cascading multiple metasurfaces into a single metasystem, promotes new combinations of functions that cannot be achieved with single‐layered metasurfaces. In this study, an all‐dielectric metasurface doublet (MD) is developed and implemented by vertically concatenating two arrays of rectangular nanoresonators on either side of a quartz substrate, in which distinct phase profiles are encoded for transverse magnetic and transverse electric polarized light. Multifunctional beam manipulation with concurrent increased beam deflection, beam reduction, and polarizing beam splitting is achieved at telecommunication wavelengths near 1550 nm. The MD is accurately created via lithographical nanofabrication, thus eliminating the extremely demanding post‐fabrication alignment. The proposed multifunctional metasurface is highly anticipated to expedite the development of advanced technologies for large‐scale photonic integration, optical metrology, light detection and ranging, spectroscopy, and optical processing.

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
