Abstract :
We report efficient poling of an electro-optic polymer and higher mode confinement in a electro-optic (EO) polymer/TiO2 multilayer slot waveguide modulator. >400-nm-thick EO polymer sandwiched between two 100-nm-tick TiO2 layers shows a mode confinement factor of 68 %, which results in lower half wave voltage (Vπ) of 2.0 V for an electrode length (Le) of 10mm at a wavelength of 1550nm (VπLe product of 2.0 V· cm). An in-device EO coefficient was 78 pm/V, using a low-index (1.621) guest-host EO polymer.
