Electric Field Tuning of BaTiO3-on-Silicon Multi-Ring Resonators via the Pockels Effect
Abstract
We demonstrate optical tuning in hybrid barium titanate-silicon photonic structures. Individual resonances of a multi-ring resonator are coalesced into a single resonance. Critically, device operation is stable in time. Our devices enable adjustable wavelength filters and offer a low power solution to compensate fabrication imperfections.
