Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

open access: yesAdvanced Materials Technologies, EarlyView.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces

open access: yesAdvanced Optical Materials, EarlyView.
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

The Role of Optical Centers in Neodymium‐Doped Calcium Fluoride: Optical Tagging and Nanothermometry in the Second Biological Window

open access: yesAdvanced Optical Materials, EarlyView.
Tuning excitation by only 6 nm unveils three distinct optical centres in CaF2:Nd3⁺,Y3⁺, each with unique spectral fingerprints. Some exhibit properties ideal for precise nanoscale temperature sensing. Abstract Nd3+ has been proposed for nanothermometry in biological media, as both its emission and excitation wavelengths fall within the regions of low ...
