Metasurface holograms for visible light

Metasurface holograms for visible light

15 Nov 2013 | Xingjie Ni, Alexander V. Kildishev & Vladimir M. Shalaev
The article presents the experimental demonstration of ultra-thin metasurface holograms that operate in the visible light range, with a thickness of only 30 nm. This is the thinnest hologram capable of providing both amplitude and phase modulation, generating high-resolution, low-noise images. The metasurface hologram is designed using Babinet-inverted complementary nanoantennas (CNAs) on a thin metallic film, which modulate the phase and amplitude of cross-polarized light. The design and fabrication process are detailed, including the mapping of the phase and amplitude distribution of the electric field onto the metasurface plane. The holographic images of the letter 'P' are successfully generated and compared with simulated results, showing high resolution and low noise. The metasurface hologram achieves an overall efficiency of about 10%, which is significantly higher than existing metamaterial holograms. The study highlights the potential of metasurfaces for advanced optical applications, such as compact and efficient optical components.The article presents the experimental demonstration of ultra-thin metasurface holograms that operate in the visible light range, with a thickness of only 30 nm.
