Tunable metafibers: remote spatial focus control using 3D nanoprinted holograms on dual-core fibers

The generation of tunably focused light at remote locations is a critical photonic functionality for a wide range of applications. Here, we present a novel concept in the emerging field of Metafibers that achieves, for the first time, fast, alignment-free, fiber-integrated spatial focus control in a…

Advanced remote focus control in multicore meta-fibers through 3D nanoprinted phase-only holograms

In this study, we present an unexplored approach for remote focus manipulation using 3D nanoprinted holograms integrated on the end face of multi-core single-mode fibers. This innovative method enables precise focus control within a monolithic metafiber device by allowing light coupled into any of the…

Capillary-assisted flat-field formation: a platform for advancing nanoparticle tracking analysis in an integrated on-chip…

Here, we present the concept of flat-field capillary-assisted nanoparticle tracking analysis for the characterization of fast diffusing nano-objects. By combining diffusion confinement and spatially invariant illumination, i.e., flat-fields, within a fiber-interfaced on-chip environment, ultra-long trajectories…

Coupled waveguide model for computing phase and transmission through nanopillar-based metasurfaces

Dielectric metasurfaces are important in modern photonics due to their unique beam shaping capabilities. However, the standard tools for the computation of the phase and transmission through a nanopillar-based metasurface are either simple, approximating the properties of the surface by that of a single…

Fiber-based 3D nano-printed holography with individually phase-engineered remote points

The generation of tailored light fields with spatially controlled intensity and phase distribution is essential in many areas of science and application, while creating such patterns remotely has recently defined a key challenge. Here, we present a fiber-compatible concept for the remote generation of…
