Large Bidirectional Refractive Index Change in Silicon‐rich Nitride via Visible Light Trimming

Advanced Optical Materials, EarlyView.
Continuous‐wave visible light trimming of PECVD silicon‐rich nitride micro‐ring resonators enables precise, large bidirectional refractive index tuning. Resonance shifts as fine as 10 pm are achieved with a cost‐effective setup, demonstrating large red shifts of 49.1 nm and blue shifts of 10.6 nm.

Thermal Dynamics Induced by Surface Acoustic Waves in Lanthanide‐Doped Core@Multishell Nanoparticles

Advanced Optical Materials, EarlyView.
Accurate local temperature readout in integrated nanoscaled devices driven by high‐frequency surface acoustic waves (SAWs) has a strong technological interest. This image illustrates how lanthanide‐doped core@multishell nanoparticles can be employed as local temperature probes in SAW applications.

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

Advanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...
