| Abstract(in English) | In this report, we present the novel electrooptic SSB modulators operated in the millimeter-wave frequency region by use of periodically polarization-reversed structure. Adopting the periodically polarization-reversed structure for the quasi-velocity-matching to traveling-electrode Mach-Zehnder intensity modulators and shifting the polarization-reversed patterns of the two straight waveguides of the Mach-Zehnder interferometer with a quarter period, we can obtain efficient balanced modulation with a quadrature phase shift. In this work, we used a novel electrode design and a polarization-reversal design for high SSB modulation characteristics. The fabricated modulator exhibited good SSB modulation performances around the designed modulation frequency of 38GHz. The measured extinction ratio between modulation sidebands was over 30dB. |
