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…
