Electro-optic (eo) modulators for ultra-wide bandwidth optical communication systems are being developed using BaTiO3 ferroelectric thin films. These modulators have low voltage-length products at 1-1.6 micron wavelengths. Realization of high-speed traveling-wave BaTiO3 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 SiO 2 buffer layer. Its microwave and electro-optic response are characterized.
