| Outline of Final Research Achievements |
I demonstrated my own proposed novel electro-optic (EO) polymer/TiO2 vertical slot waveguide modulators. I reduced the thickness of the EO polymer down to 0.3 micron and obtained the waveguiding and simultaneously reduced the electrode distance. I successfully obtained optical modulation from the vertical slot waveguide at the first time. I increased mode confinement in the thin EO polymer and poling efficiency using low-index and mesoporous sol-gel silica layer as an interfacial layer in the slot waveguide modulators. I also increased the electrical conductivity of the sol-gel silica cladding to increase the poling efficiency. As a result, I obtained comparably low half wave voltage and electrode length produce (VpiL) of 2.0 Vcm even though EO coefficient is lower (78 pm/V) than that of previously demonstrated high performance EO polymers. These demonstrated polymer modulates enables low power consumption in future optical interconnection
