Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

High‐Tc Superinductors Through Tailored Metamaterial Losses
Advanced Optical Materials, EarlyView.This work presents a loss‐engineering approach for designing high‐temperature superconducting superinductors using YBCO metamaterials. By analyzing radiative and ohmic losses through coupled‐mode theory, the study reveals that partial ohmic loss supports superinductance in thinner films.

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms
Advanced Optical Materials, EarlyView.This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.
