30 GHz 带通调制器是在畴反转 LiNbO3 衬底上制造的。分析了晶圆级极化过程中电路对电流波形的影响，并在极化过程中精确控制了畴壁的运动。互补极化反转技术使单电极结构的器件能够进行平衡调制。通过抑制载波的双边带调制生成 60 GHz 光载波。所制造的器件表明，载波抑制优于 45 dB，并且 60 GHz 间隔双音光波信号与抑制载波的功率比为 35 dB。
A 30 GHz bandpass modulator was fabricated on a domain reversed LiNbO3 substrate. The circuit effect on current waveforms during wafer-scale poling was analyzed, and the domain wall movement was precisely controlled in the poling process. A complementary polarization reversal technique enabled the device with a single electrode structure to perform balanced modulation. A 60 GHz optical carrier was generated by double sideband modulation with the suppressed carrier. The fabricated device showed that carrier suppression was better than 45 dB and that the power ratio of a 60 GHz spaced two-tone lightwave signal to the suppressed carrier was 35 dB.
