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 ...

Inverse Scattering Method Design of Regrowth-Free Single-Mode Semiconductor Lasers Using Pit Perturbations for Monolithic Integration

IEEE Photonics Journal, 2018
An inverse scattering method is used to design regrowth-free single-mode lasers, using etch depth insensitive pits as perturbations in the laser cavity. These pit perturbations are circular holes etched into the waveguide of each laser to a depth 0.8$\mu
