Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation
Advanced Materials Technologies, EarlyView.A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

Unidirectional Focusing of Light Using Structured Diffractive Surfaces
Advanced Optical Materials, EarlyView.This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.

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.

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2
Advanced Optical Materials, EarlyView.The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...
