Paper Abstract

In the report, we explain how the quasi-velocity-matched electrooptic (EO) modulator using domain inversion can generate extreme wide sideband. The quasi-matching between the phase velocity of microwave and the group velocity of light was established by using periodic domain inversion of an EO crystal LiTaO3 at a frequency of 9.35 GHz. Long effective interaction length was also obtained at such a high modulation frequency. As a result, we obtained modulation index 22.5 rad and extended the sidebands up to 420 GHz.
