| Research Abstract |
We demonstrated novel hybrid sol-gel silica/electro-optic (EO) polymer directional coupler switches, and long-term stability for a hybrid sol-gel silica/EO polymer modulators. Moreover, we enhanced the applied field by one order of magnitude in novel multilayer slot waveguide modulators, after experimental and numerical analysis was performed for the reduction of the inter-electrode distance in the waveguides. We reduced the inter-electrode distance down to 1μm in the multilayer slot waveguide modulators without suffering further optical loss, which results in ten times enhancement of the field.
