Integrated Nonlinear Photonics with TiO2-Ta2O5 Mixtures

Not Accessible

Your library or personal account may give you access

Abstract

We explore four-wave-mixing processes in nanophotonic waveguides of titania-doped tantala, demonstrating microresonator quality factors up to 3.6 ± 0.7 × 106. Ion-beam sputtering enables a new direction towards controlling and optimizing integrated nonlinear optics, using amorphous material mixtures.
