This is a student seminar.
Abstract:
Integrated quantum photonics requires highly efficient electro-optic modulators to interface classical electronics with the quantum domain. While epitaxial Barium Titanate (BTO) offers a massive electro-optic response compared to standard materials, transitioning it to the thin-film regime introduces microstructural challenges that directly impact optical properties. In this talk, I will present our steps in developing a toolkit for characterizing BTO thin films. I will review our primary measurement architectures including automated prism coupling, and Sénarmont polarimetry, and discuss how evaluating intrinsic propagation losses paves the way for ultra-compact, sub-volt quantum devices.
