Recently it was shown that high-resolution holograms can be realized by using plasmonic metasurfaces. Combining nonlinear metasurfaces and holography can lead to new highly unconventional and versatile optical devices.
Here, we show a way to generate nonlinear holograms in the visible spectral range by using Second Harmonic Generation. For this purpose we fabricated a plasmonic nonlinear metasurface consisting of plasmonic nanoantennas. The desired phase for the hologram is hereby encoded in the arrangement and orientation of the antennas. By imaging the nonlinear second harmonic signal from the sample when illuminated with RCP or LCP short laser pulses we can reconstruct the image. Furthermore, we demonstrate that multiplexing of holographic images can be obtained.
