Multi-Wavelength Achromatic 3D Meta-holography with Zoom Function.

ABSTRACT: With the development of nanofabrication technology, meta-holography has shown unprecedented potential for light regulation. However, due to the wavelength mismatch, chromatic aberrations are inevitable in multi-wavelength meta-holography. Moreover, since the meta-hologram is difficult to refresh, zoom meta-holography has not been reported to date. Here, a multi-wavelength achromatic 3D meta-holography with a zoom function is developed, breaking through both the chromatic aberration interference and imaging limit for the first time. A wide-band 3D meta-hologram is generated and is used to design a wide-band metasurface fabricated with nanostructures based on the Pancharatnam-Berry phase, thus achieving the multi-wavelength meta-holography.
