Development of Optical Modulator

with Superconducting Resonance Eletrodes

[Japanese Version]

[Abstract]

　 Sub-carrier transmission system in which microwave signal is carried by light wave has been proposed recently. For this application, we are studying a low voltage optical modulator employing superconducting resonant-type electrodes. It is clarified that modulation signal bigger than input signal can be raised by introducing impedance matching circuit for electrodes. Furthermore, by using superconductor with high Q-factor, it is realized driving voltage can be suppressed. And we carried out preliminary study employing high-temperature superconductor electrodes.
