提出了一种利用嵌套LiNbO 3马赫-曾德尔调制器（MZM）实现本振八倍频产生光学毫米波的新方案，并进行了数值模拟。由于调制器的响应频率和本振频率大大降低，发射机对光电器件的带宽要求也大大降低。然后，对嵌套调制器的参数进行了理论分析，发现MZM的消光比和两臂之间的相位不平衡对产生的光学毫米波的性能都有影响。
What we believe to be a new scheme to generate an optical millimeter wave with octupling of the local oscillator via a nested LiNbO3 Mach-Zehnder modulator (MZM) is proposed and implemented by numerical simulation. Since the response frequency of the modulator and the local frequency are largely reduced, the bandwidth requirement of the transmitter to the optical and electrical components is reduced greatly. Then, the parameters of the nested modulator are analyzed theoretically, and we find that both the extinction ratio of the MZM and the phase imbalance between its two arms have influence on the performance of the generated optical millimeter wave.
