Three‐Dimensional Array Multicasting of Cylindrical Vector Beams Using Spin‐Multiplexed Dammann Vortex Metasurface

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

open access: yesLaser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Shear Wave Elastography to Assess Respiratory Muscle Function in Congenital Myopathies

open access: yesMuscle &Nerve, Volume 74, Issue 1, Page 103-110, July 2026.
ABSTRACT Introduction/Aims Respiratory muscle dysfunction is prevalent in congenital myopathies and often leads to respiratory failure. Ultrasound shear wave elastography (SWE) measures tissue elasticity and has been proposed as an alternative to invasive measures of respiratory muscle contractility.

Differential modal gain optimization for weakly-coupled few-mode multi-core erbium-doped fiber amplifiers

open access: yesOptics Express
Space-division multiplexing (SDM) is a key technology to overcome the capacity limit of single-mode fiber systems, using multiple spatial channels in few-mode fibers, multi-core fibers, and few-mode multi-core fibers. Few-mode multi-core erbium-doped fiber amplifiers (FM-MC-EDFAs) can compensate for transmission loss via either core or cladding pumping.
