3D Nanoprinted Polarization Optics Directly on Optical Fibers — •Tim Stechel and Markus A. Schmidt — Leibniz Institute of Photonic Technology, Albert-Einstein-Str. 9, 07745 Jena, Germany

Polarization is a fundamental property of electromagnetic radiation, influencing numerous areas of physical sciences and optical technologies. Developing functional interfaces that seamlessly integrate polarization control with fiber optics opens new opportunities for advancing these technologies. Using two-photon polymerization, we fabricate 3D structures on the sub-micron scale, directly on optical fibers. This high-resolution additive manufacturing technique enables the creation of tailored microstructures that can precisely control the polarization state of light as it enters and exits fibers. These custom interfaces are highly adaptable to different fiber types and optical configurations, allowing for enhanced polarization shaping and analysis. Here, we will present the design process, fabrication process and characterization of the fabricated structures. Our approach combines the versatility of 3D printing with the precision required for nanoscale optical engineering, providing a robust platform for research into light-matter interactions and advancing fiber-based photonic technologies. Potential applications span diverse fields, from telecommunications to advanced optical metrology, demonstrating the broad impact of integrating 3D-printed microstructures with fiber optics.
