Paper Abstract

To fabricate a low-driving voltage, high-speed x-cut lithium niobate modulator with 50-ohm electrode impedance, we introduce a novel design approach, which employs a patterned SiO2 buffer layer. Experimental results showed that the partial removal of SiO2 buffer layer was effective in both lowering driving voltage and suppressing dc-drift of the modulators.
