Electro-optic effects in polymer waveguide devices for optical communication

Electro-optic waveguide elements are fabricated in the polymer-on-silicon technology. Measured field distributions of the inverted rib waveguides show excellent agreement with vectorial FEM calculations. This method is also used for electro-optic phasemodulator design. The dynamics of electrode poling is studied by reflectrometry. An integrated waveguide interferometer with lateral electrodes allows the determination of the r33/r31 equals 3.5.
