In this paper, we analyze a traveling wave electrode as it drives a high-speed electro-optic (EO) polymer/TiO2 multilayer slot waveguide modulator by simulation. To enhance its mode confinement, the EO polymer is clipped by TiO2 slot waveguide films, and the electrode atop the active region and connection transmission line are optimized to match the impedance at 50 Ω. The optical response is over 200 GHz at 3-dB bandwidth with a 1-cm-long electrode. By comparison, the optical response with silicon TiO2 layers is only 20 GHz with transverse electric (TE) polarized light.
