MEMS‐Tunable Bilayer Plasmonic Metasurfaces for Dynamic Vortex Wave Plates

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
This work presents a MEMS‐tunable bilayer metasurface for dynamic vortex wave plates at near‐infrared wavelengths. By electrically tuning the separation between the BMS and the MEMS mirror, the device enables reconfigurable switching between l = 2 and l = −1 vortex modes, achieving >80% polarization conversion efficiency, fast response time (9 µs), and

High‐Precision Laser Spectrum Analyzer via Digital Decoherence

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
This paper presents a digital decoherence method that realizes the laser's decoherence process in the digital domain. Combined with the compact delayed self‐heterodyne interferometer, it enables accurate frequency‐noise power spectral density measurements of sub‐Hz linewidth lasers.

7T 19F/1H MRI with perfluorocarbon‐labeled immune cells in pigs: Pilot results with a dedicated twin‐array system with pTX support

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 51-61, January 2026.
Abstract Purpose Cardiac inflammation plays a key role in many diseases. However, its underlying mechanisms and progression remain poorly understood. Using an ultra‐high field (UHF) may increase the sensitivity of MRI of inflammatory processes with 19F‐labeled immune cells.

Interferometric Deflection Analysis of Suspended 2D Polyaramid Thin Films

open access: yesSmall Methods, Volume 10, Issue 1, 10 January 2026.
A visible light interferometry technique is developed to measure the deflection of 2D nanofilms, replacing AFM‐based methods. Using theoretical and semi‐empirical models, multicolor interference patterns from broadband excitation are translated into nanoscale deflection estimates.
