In this talk we present on recent advancements in hybrid-glass waveguides on silicon photonic platforms. We describe novel monolithic hybrid integration approaches and waveguide designs for functional glass claddings on silicon-on-insulator (SOI). We describe our results on low-loss hybrid tellurite-silicon waveguides, high-Q resonators, and amplifiers and lasers and our recent efforts to optimize their performance and utility in silicon photonic systems. Such devices are promising for new functionalities in sensing, metrology, computing, and communications applications.
We present on recent progress on a hybrid tellurite glass and silicon nitride photonic platform. We show low loss waveguides and Q factors < 10^6 in microring resonators. We also show rare-earth-doped active devices, including erbium-doped and thulium-doped waveguide amplifiers and thulium-doped microring lasers. Using the same approach, we demonstrate nonlinear functionalities including efficient four-wave-mixing, supercontinuum generation and third harmonic generation in compact microring resonators and waveguides. The platform is highly promising for compact and low-cost passive, active and nonlinear photonic integrated circuits for applications in computing, communications, sensing and metrology.
