We present the design, fabrication, and characterization of integrated Bragg gratings in silicon-on-insulator slot waveguides. The Bragg gratings are formed with sidewall corrugations, either on the inside or on the outside of the waveguide. We demonstrate resonators implemented using phase-shifted Bragg gratings in slot waveguides, showing quality factors up to 3 × 10(4). Due to the strong optical confinement in the slot, these devices are promising for optical sensing applications. The devices were fabricated using a CMOS-compatible process, facilitating high-volume and low-cost production.
