| Outline of Final Research Achievements |
The EO polymers offer intrinsic advantages such as a large EO coefficient, high bandwidth, low dielectric constant and loss, and excellent compatibility with other materials and substrates. In this study, we showed the EO polymer waveguide modulator having small driving voltage and high-bandwidth properties. The waveguide consists of the high refractive index core and the EO polymer cladding. Such a hybrid structure was advantageous to increase the EO activity due to the high poling efficiency compared to the common polymer waveguides. The measured half-wave voltage was 0.9 V. We tested the high-speed response of the hybrid EO polymer modulator by applying RF frequency signals up to 40 GHz. We measured the transmission spectra under the high-frequency modulation by using the sideband analysis technique. Clear sideband spectrum consisting of the optical carrier and modulated signals was obtained for 10-40 GHz. The half-value change in the index was observed at 23 GHz and 25% at 40 GHz.
