Abstract An optical waveguide for a polymer modulator based on organic/inorganic hybrid electro-optic (EO) materials is designed and fabricated by utilizing a strip-loading structure. This hybrid material has a controllable refractive index, high EO coefficient and good poled stability, which are suitable for the EO modulators and switches. The embedded waveguide made of the above EO material can reduce the coupling loss. The light is coupled into the guided-core layer and then undergoes a transition from the buried waveguide into the EO material. Obvious modulation is observed by application of ac voltage to the EO material. The measured Vπ of co-planar waveguide (CPW) is 5V for the Mach-Zehnder (MZ) modulator in length of 3.5cm.
