本文对基于光载波抑制（OCS）技术的多级级联强度调制器产生高重复频率毫米波进行了数值模拟和实验研究。通过调节射频信号的重复频率和强度调制器上射频信号之间的相位关系，找到了产生高重复频率毫米波的规律。基于这一规则，我们已经实验证明可以产生超过80GHz的光学毫米波。
We have numerically and experimentally investigated how to generate high-repetitive frequency millimeter (mm)-wave using multi-cascaded intensity modulators based on optical carrier suppression (OCS) scheme. We have found the rule how to generate the high-repetitive frequency mm-wave by adjusting the repetitive frequency of the radio-frequency (RF) signals and the phase relation between the RF signals on the intensity modulators. Based on this rule, we have experimentally demonstrated to generate over 80GHz optical mm-wave.
