Metaphotonics meet fibers: a novel pathway towards boosting incoupling efficiencies and single-fiber optical trapping

Abstract

Here we present that interfacing optical fiber with nanostructures defines a novel class of fiber-integrated devices – nanostructure-interfaced fiber – allowing to reach new domains of applications for Fiber Optics research. Through 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 allows for efficient light incoupling at angles as large as 80° and for trapping polymer microbeads with one single-mode fiber device. Show more
