Abstract

We present a hybrid vanadate/silicon-photonics platform that integrates vanadate nanostructures with silicon-on-insulator (SOI) waveguides for high-performance functional passive building blocks at telecommunication wavelengths. Comprehensive numerical analysis is performed to study the mode hybridization in a hybrid waveguide structure that comprises a silicon ridge separated from a vanadate substrate. Studies on the impact of key geometric parameters reveal that the coupling between vanadate and photonic structures result in highly confined hybrid modes with extreme field confinement and significantly larger effective indices as compared to hybrid plasmon polarizations (HPPs) supported by noble-metal-based waveguiding systems. By leveraging the unique confinement and modal properties offered by vanadate material, we explore the feasibility of building ultra-compact waveguide attenuators and …
