Optical, electrical, processability, and film casting characteristics of various conductive cladding layers were investigated. The goal was to find conductive polymer cladding materials suitable for fabricating and optimizing waveguide electro-optic modulators. Using cladding material that is more conductive than the core material, the poling fields in the core will be maximized, realizing a maximum electro-optic coefficient, which reduces the operating voltage in waveguide electro-optic modulators. We found, however, that there are tradeoffs between absorption losses, conductivity, refractive index, materials processability and materials compatibility when using off-the-shelf materials.
