Replacing curved and bulky optical elements with thin and lightweight counterparts is a persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial metamaterials, have attracted much attention because of their exceptional ability to manipulate electromagnetic waves such as amplitude, phase, polarization, propagation direction, and so on. With the great advances in planar digital optics and vector optical field manipulation via metasurfaces, planar optics with multiscale optical field manipulation from subwavelength meta-atoms (tens of nanometers) to large-scale planar devices (hundreds of millimeters) is highly desired in practical applications, which may replace conventional optical devices with superior performance and decreased weight or even create completely new functionalities. Here, we give a perspective on the multiscale optical field manipulation based on planar optics. Particular emphasis is given to multifunctional optical field manipulation, intelligent design, and mass fabrication, as well as their potential applications in lightweight laser systems, diffractive sails, integrated optics, etc.

“…[ 65,124 ] In addition, based on Malus's law, metasurfaces composed of anisotropic resonators have been widely used to manipulate the optical amplitude at one or multiple fixed linear polarization directions. [ 125–127 ] Metasurfaces designed based on Malus's law can realize optical amplitude manipulation in a broad bandwidth and the operation bandwidth is mainly decided by the resonant bandwidth of the metasurfaces. [ 128 ] Due to the excellent capacity of metasurfaces on frequency‐dependent optical amplitude manipulation at the subwavelength scale, they have been widely used for the realization of high‐level gray imaging and optical encryption.…”

Recent rapid progress in metasurfaces is underpinned by the physics of local and nonlocal resonances and the modes coupling among them, leading to tremendous applications such as optical switching, information transmission, and sensing. In this review paper, an overview of the recent advances in a broad range of dimensional optical field manipulation based on metasurfaces categorized into different classes based on design strategies is provided. This review starts from the near‐field optical resonances of artificial nanostructures and discusses the far‐field optical wave manipulation based on fundamental mechanisms such as mode generation and mode coupling. The recent advances in optical field manipulation based on metasurfaces in different optical dimensions such as phase and polarization are summarized, and newly‐developed dimensions such as the orbital angular momentum and the coherence dimensions resulting from phase modulation are discussed. Then, the recent achievements of multiplexing and multifunctional metasurfaces empowered by multidimensional optical field manipulation for optical information transmission and integrated applications are reviewed. Finally, the paper concludes with a few perspectives on emerging trends, possible directions, and existing challenges in this fast‐developing field.

“…[1][2][3] By simulating the propagation and interference of object light waves Metasurface, [4][5][6][7][8] a two-dimensional artificial material characterized by an array of subwavelength structures sitting on a planar substrate, has shown its unprecedented ability to precisely manipulate the fundamental optical parameters of incident light waves. [9][10][11][12][13] There are abundant achievements in the study of phase [14][15][16][17][18][19][20] and amplitude [21][22][23][24][25] modulation by metasurfaces. Compared with phase-or amplitude-only meta-elements, [26][27][28][29][30][31][32][33] complex-amplitude meta-elements have attracted extensive interest due to their ability to independently and flexibly manipulate the two important optical parameters, i.e., amplitude and phase.…”

through numerical calculation, one can encode the amplitude and phase of light waves into a CGH, and finally reconstruct the three-dimensional (3D) light field carrying object information through optical diffraction. In this process, a functional element with precise complex-amplitude modulation is the key to the digital encoding of holograms and the modulation of light waves. The modulation ability of light waves affects the numerical characteristics and reconstruction effect of holograms. An ideal complex-amplitude hologram can record the complex-amplitude information including the amplitude and phase of the object. However, since most of the existing optical elements such as conventional hologram recording with photographic negative, diffractive optical elements, and spatial light modulator (SLM) can only modulate the amplitude or phase of light wave, the hologram needs to be converted from the complex-amplitude to the pure amplitude or phase accordingly. With the development of new artificial materials such as metasurfaces, complex-amplitude hologram coding technology has attracted more and more attention due to its high spatial bandwidth product and high reconstruction accuracy.Optical complex-amplitude determines the propagation behavior of light in free space to the maximum extent. Precise control of complex-amplitude is the key to generating user-defined light fields. Current attempts to control optical complex-amplitude using metasurface, however, either have limited amplitude/phase step numbers or lost high lateral resolution since amplitude and phase are usually manipulated with size-varied nanostructures or several nanostructures integrated into a unit-pixel. Here, it is shown that bilayer metasurface can readily decouple optical amplitude and phase, thus achieving arbitrary complex-amplitude modulation only by arranging the orientation angles of nanostructures. In this design, each unit-pixel in one layer has only one nanostructure with the same size, thus significantly increasing the lateral resolution of complex-amplitude modulation. More importantly, the approach of controlling optical complex-amplitude merely by changing nanostructure orientation can significantly simplify the metasurface design and aggrandize the fabrication tolerance, thus enhancing the robustness of metasurfaces toward practical applications.
