Femtosecond laser plasmonic nano-printing metasurfaces for multiple-dimensional manipulation of light fields

Abstract

Metasurfaces enable the multidimensional manipulation of light fields in a subwavelength scale. However, the low-cost preparation of large-area metasurfaces is still a challenge. In this Letter, we first, to the best of our knowledge, use the laser plasmonic nano-printing technique to efficiently manufacture metasurfaces with multidimensional manipulation capability. By utilizing a phase-polarization mapping method, we fabricated a silicon-based metasurface for color display, and indium tin oxide-based metasurfaces for decoupled near- and far-field holographic displays. This flexible and efficient laser plasmonic nano-printing method has great potential in the preparation of large-area metasurfaces, and is of great significance to promote the practical application of metasurfaces.

“…[18][19][20][21] These merits endow this laser nanopatterning technique to be potent for scalable, low-cost, and fast manufacturing of metasurfaces. [22][23][24][25][26] Nevertheless, most LIPSS are usually nanogratings that exhibit an obvious anisotropic property. The fabricated devices with one-dimensional nanogratings are usually polarization-sensitive due to the unidirectional characteristics in structure.…”
