High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization

Advanced Photonics Research, Volume 6, Issue 9, September 2025.
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...

Quantitative Electron Beam‐Single Atom Interactions Enabled by Sub‐20‐pm Precision Targeting

Advanced Science, Volume 12, Issue 34, September 11, 2025.
Atomic lock‐on (ALO) is a rapid, low‐dose in situ technique in scanning transmission electron microscopy (STEM) that achieves sub‐20 picometer (pm) beam positioning. A sparse annular scan collects positional information while avoiding irradiation of the target site.

Short‐term gradient imperfections in high‐resolution EPI lead to Fuzzy Ripple artifacts

Magnetic Resonance in Medicine, Volume 94, Issue 2, Page 571-587, August 2025.
Abstract Purpose High‐resolution fMRI is a rapidly growing research field focused on capturing functional signal changes across cortical layers. However, the data acquisition is limited by low spatial frequency EPI artifacts; termed here as Fuzzy Ripples.
