Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures

open access: yesLaser &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

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

open access: yesSmall, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Full‐field X‐ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

open access: yesJournal of Synchrotron Radiation, EarlyView.
The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

Head-tracked 3D displays

open access: yes, 2022
S.460-463There are several approaches to providing a 3D display, the generic types being: binocular, multiple-view, volumetric, and holographic. A binocular display is one where only two images are presented to the viewers. The viewing regions may occupy

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

open access: yesJournal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Measuring Lead Userness: Development and Validation of a Hierarchical Scale

open access: yesCreativity and Innovation Management, Volume 34, Issue 4, Page 944-962, December 2025.
ABSTRACT Lead user theory has gained traction in both academia and practice, given that involving lead users (LUs) can yield more innovative and commercially successful products. Yet, measurement inconsistencies have hindered consensus on how to reliably assess lead userness.

Extended Reality in Endodontics: A Review of Current Applications and Future Potential

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.
