Abstract
Metasurface technology has allowed the use of ultrathin optical materials to realize complete control of the amplitude, phase, and polarization of light, leading to a versatile platform for optical wavefront manipulation with nanoscale resolution. However, conventional metasurface fabrication relies on planar lithography methods that lead to metasurfaces with limited design freedom in a 2D plane. Here we present the design and 3D laser nanoprinting of 3D meta-optics in a polymer matrix with unlocked height degree of freedom. We show that these 3D-nanoprinted metasurfaces can be used for high-bandwidth holography and on-fiber wavefront engineering.
