Abstract

Design and performance of a LiNbO3 (LN) optical modulator for subcarrier optical transmission employing a high gain superconducting booster circuit have been studied. Based on a new design theory for the high gain booster circuit, we designed a voltage amplifier with center frequency of 10 GHz, bandwidth of 5 MHz, and the voltage gain of 33 dB using an electromagnetic wave simulator. A preliminary experiment with YBCO electrode on MgO substrate flip chip bonded on LN optical waveguide has also been made.
