Barium Titanate: an emerging ferroelectric material for efficient electro-optic modulation
On demand | Presenting live 29 January 2025 
Abstract
Barium Titanate (BTO), a material having a robust electro-optic effect (due to a large Pockel’s coefficient), high second-order nonlinearity, low 3rd -order nonlinearity, ultra-low optical absorption having pure phase modulation, broad transmission spectrum and linear response to an applied field makes it a suitable candidate for developing Electro-Optic (EO) modulators. We present a cogent work analysis of the fabrication process development to make low-loss monolithic waveguides on a thin film BTO platform. We study the material’s behavior as low-loss waveguides in an optical simulation environment built on Lumerical Mode solver and characterize the waveguides using atomic-force microscopy, scanning electron microscopy and optical back-scattering reflectometry.
