Abstract
In this work, we have fabricated a waveguide using a TiO2 core and an EO polymer cladding. As the high refractive index TiO2 core is thin, a large fraction of the optical TM mode extends into the cladding, which is the rationale for selecting an EO polymer cladding [1]. As a result, our waveguide can be constituted without a transparent cladding, which makes the interelectrode gap smaller than the traditional three-layer waveguides. This TiO2 layer also has the function of improving the poling efficiency of the EO polymer to attain a high r33 level, due to the blocking of excessive charge injection and the reduced the current leakage. Combining all of these merits together, the resulting fabricated waveguide exhibited a VπL figure of merit and propagation loss of 3.3 V-cm and 3.0 dB/cm, respectively.
