Abstract

We report efficient poling of electro-optic polymer in hybrid electro-optic (EO) polymer/TiO₂ multilayer waveguide modulator on mesoporous sol-gel silica cladding. The mesoporous sol-gel silica has ~nm size of porous structure with lower refractive index of 1.24, which improves poling efficiency and mode confinement in the 400nm-thick thin EO polymer film in the modulators. The cladding prevents optical absorption more efficiently from lower Au electrode. Half wave voltage (V_π) of the modulator fabricated on the mesoporous sol-gel silica cladding is 6.0 V for the electrode length (L_e) of 5-mm at 1550nm wavelength (V_πL_e product of 3.0 V· cm). In-device EO coefficient was 75 pm/V, using low-index guest-host EO polymer.
