Fig. 1. (a) Sketch of reflective nanosieves composed of aluminum meta-mirrors that could sieve reflective photons for holography. (b) Reflectance of visible light from the 100-nm-height meta-mirrors with different diameters from 50 nm to 200 nm. (c) Transmission of light through the classic nanosieves. To be consistent, the thicknesses of meta-mirrors and nanoholes are 100 nm, and their periods are also kept with the same value of 250 nm. Both nano-mirrors and nanoholes have the same diameters from 50 nm to 200 nm.

Fig. 2. (a) Sketch of meta-mirror-based hologram. The total size of the hologram is 200 µm × 200 µm. (b) Designed meta-mirrors for the hologram. The white region stands for the meta-mirrors. The right panel shows the zoomed-in pattern, which clearly gives the details of meta-mirrors. (c) Simulated intensity profile at the target plane of z₀ = 1 mm at the wavelength of λ₀ = 532 nm. (d) Scanning-electron-microscopy (SEM) image of the fabricated meta-mirrors. It displays the region encircled within the green rectangle in (b).

Fig. 3. (a) Experimental setup for the meta-mirror hologram characterization. BS: beam splitter. (b) Measured intensity profiles (raw data) at the exemplified wavelengths. (c) Simulated (curve) and experimental (asterisks) efficiency at the interested wavelengths.
