Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

Advanced Materials, EarlyView.
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 ...
