Metasurfaces meet optical fibers: a novel platform for flexible optical trapping and boosting in-coupling efficiencies

Abstract

In this talk, we show that the combination of optical fibers with nanostructures defines a new class of fiber integrated devices — nanostructured fibers — which opensup new application areas for optical fiber research. Using 3D nanoprinting and modified electron beam lithography, we integrate high-NA meta-lenses and dielectric ring gratings onto the end faces of single-mode fibers. These devices enable efficient light coupling at angles up to 80° and trapping of Escherichia coli bacteria with an individual single-mode fiber device. Show more
