Merging Nanophotonics with Optical Fibers through 3D Nanoprinting: a novel platform for flexible beam manipulation

Abstract

Here, we will demonstrate how the fusion of optical fibers with nanostructures creates a new category of fiber-integrated devices 3 hybrid optical fibers - that unlocks novel applications. We achieve this by leveraging 3D nanoprinting, which is highly compatible with the fiber geometry, to integrate high-NA holographic metalenses, achromatic metasurface-based lenses, and dielectric ring-like gratings onto the end faces of single-mode fibers, allowing to trap biological relevant objects, to focus light across the telecommunication range, and to boost incoupling efficiencies.
