Abstract

Here I will report on optical fibers that are interfaced with dielectric nanostructures and demonstrate their properties on the examples of optical trapping and tracking of single nano-objects. The first topic addresses the implementation of nanostructures on fibers by 3D nanoprinting. This allows microspheres and bacteria to be trapped with only a single-mode fiber by integrating meta-lenses on the fiber end faces, achieving numerical apertures of up to 0.88. Through modified electron-beam lithography, I will show that incoupling efficiencies into fiber can be boosted by orders of magnitude.
