Nonvolatile Tuning of Bragg Structures Using Transparent Phase-Change Materials
Nicholas A. Nobile, Chuanyu Lian, Hongyi Sun +7
Bragg gratings offer high-performance filtering and routing of light on-chip through a periodic modulation of a waveguide's effective refractive index. Here, we model and experimen…

In-memory photonic dot-product engine with electrically programmable weight banks
Wen Zhou, Bowei Dong, Nikolaos Farmakidis +7
Electronically reprogrammable photonic circuits based on phase-change chalcogenides present an avenue to resolve the von-Neumann bottleneck; however, implementation of such hybrid…
