The first successful realisation of high-speed travelling-wave BaTiO 3 thin-film electro-optic waveguide modulators with 3 dB modulation bandwidth of 15 GHz at 1.55 μm wavelength is reported. Quasi-velocity-matched electrodes for BaTiO3 thin-film modulators are achieved by addition of a SiO2 buffer layer. Its microwave and electro-optic response are characterised.
