Advanced Technology for 3D Nanoprinting
Proceedings International, 2020 Today, additive manufacturing research and development rely heavily on 3D printing. While there is a wide choice of commercial 3D printers, few reach nanometer resolution and feature size. The difficulties arise from special high precision required for materials delivery and registry among layers in the printing process. Scanning probe microscopy (SPM)

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures
Laser &Photonics Reviews, EarlyView.A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency
