Refractive Index Modification in Thin Film Barium Titanate-on-Insulator and Dry Etch Free Fabrication of Waveguide Devices
2023 IEEE PHOTONICS CONFERENCE, IPC(2023)
Abstract
We present refractive index modification methods in thin-film barium titanate-on-insulator with a resultant index change up to 0.17, and propose dry etch free device fabrication methods for optical waveguide devices.
