which possess orbital angular momentum associated with helical phase-front. [3][4][5][6] Vector vortex beams (VVBs), as the name implies, possess the properties of both vector beams and vortex beams (i.e., with tailored phase and polarization distribution). The VVBs have been used for particle trapping, [7,8] optical communication, [9] quantum information, [10] high-resolution lithography, [11] etc. However, the applications of VVBs (as well as vortex beams) are limited as their annular intensity profiles vary with their topological charges [12] due to the incapable of amplitude control. This property may cause problems when compositing VVBs, as the intensity profiles of different VVBs cannot closely coincide with each other. To be specific, when the composited VVBs propagate, the state of polarization becomes unstable [13] and the intensity profile collapses, [14] which inevitably limits the co-propagation of multiple VVBs in optical system. Recently, Ostrovsky and co-workers [15] introduced the concept of perfect vortex beam (PVB), which has an annular intensity profile independent of topological charge. Plenty of methods to obtain the PVB have been proposed, such as using spatial light modulator, [15,16] axicon, [17] etc. By combining the generation methods of PVB with the Sagnac interferometer, perfect vector vortex beams (PVVBs) are also demonstrated, [18] which is able to possess stable state of polarization and intensity profiles upon propagation. The generation of PVVBs can be ultimately considered as the success of tailoring the APP of light. However, all these schemes to obtain the PVVBs and PVBs require a large number of bulky optical elements, which cannot be straightforwardly downsized, preventing widespread applications in miniaturized and integrated optical systems.Metasurface is planar structure that can locally manipulate the optical properties of light at subwavelength scales. [19,20] It has been widely used in many areas, including metalens, [21][22][23] holography, [24][25][26][27] vortex beams, [28][29][30][31] VVBs, [32][33][34][35][36][37] etc. However, the generation of VVBs using metasurface cannot realize arbitrary polarization and phase distributions, and mostly of them are limited to linear polarization, [32][33][34][35][36] such as radially or azimuthally polarized beams. Most importantly, all the demonstrated VVBs based on metasurface are not perfect, that is, their annular intensity profiles are dependent on the topological charges.Vector vortex beams (VVBs) possess ubiquitous applications from particle trapping to quantum information. Recently, the bulky optical devices for generating VVBs have been miniaturized by using metasurfaces. Nevertheless, it is quite challenging for the metasurface-generated VVBs to possess arbitrary polarization and phase distributions. More critical is that the VVBs' annular intensity profiles demonstrated hitherto are dependent on topological charges and are hence not perfect, posing difficulties in spatially shared co-propagation of multiple vortex be...

“…The study of metasurface holography has been carried out to increase the amount of information on one metasurface. This method is made possible by using a new structure, controlling the properties of incident light, or using a reflection space as modulating range with transmission space [21,[52][53][54][55][56][57][58][59]. The phase control via PB phase is well known to have a broadband characteristic [21,29,51].…”

“…As this mechanism employs the titanium dioxide meta-atom of which efficiency is up to 100% in visible frequency, no polarizer is needed at the output terminal. Thanks to the efficient nature of dielectric metasurface, the meta-atom was designed to impart distinct phase retardation by the incident angle, that is, the direction of the incident light [55,56,[66][67][68]. In Figure 2H, the shape of the structure is carefully adjusted to impart a different phase according to the incident angle [55].…”

Metasurfaces have received enormous attention thanks to their unique ability to modulate electromagnetic properties of light in various frequency regimes. Recently, exploiting its fabrication ease and modulation strength, unprecedented and unique controlling of light that surpasses conventional optical devices has been suggested and studied a lot. Here, in this paper, we discuss some parts of this trend including holography, imaging application, dispersion control, and multiplexing, mostly operating for optical frequency regime. Finally, we will outlook the future of the devices with recent applications of these metasurfaces.

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
