Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials
Advanced Materials, Volume 38, Issue 31, 2 June 2026.Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers
Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.
