• Microwave characteristics of a LiNbO_3 optical modulator employing superconductor electrodes (Pb-In-Au) as a transmission line of a traveling signal has been studied experimentally in the temperature range from 300 K to 4.2 K. At frequencies between 8 GHz and 12 GHz it is shown that the obtained modulation efficiency increases as expected from theory when the superconductor undergoes the transition from a normal state to a superconducting state. The present results dumonstrate the possible applications of superconducting electrodes to high performance LiNbO_3 optical modulators.
