Paper Abstract

We propose a novel electrooptic (E/O) phase modulator using domain inversion of a part of an E/O crystal. The domain inversion is achieved by applying a high electric field to an E/O crystal at room temperature. We made an E/O modulator of an LiTaO3 with this method and experimentally confirmed the operation of the Quasi-Velocity matched E/O modulator at high microwave frequency. As a result, we obtained ultrawide modulation spectra of 1.85 THz width.
