中文摘要：

提出并实现了一种新的产生毫米波的六倍频技术。采用两个相同的串联马赫一曾德电光调制器（MZM），调节第1个MZM调制器的偏置电压使其工作在最小传输模式，只输出奇次光谐波分量；调节第2个MZM调制器的偏置电压使其工作在最大传输模式，抑制所有的奇次光谐波分量。实验显示，采用10GHz的射频（RF）信号驱动这两台MZM调制器后，可输出60GHz的毫米波信号，实现了频率的6倍频，并且输出的信号经过50km光纤传输后，受到色散影响小。

英文摘要：

We propose and investigate a novel technique for the generation of millimeter-wave （mm-wave）,i, e. , frequency sixuplexing technique. The proposed technique adopts two cascaded Mach-Zehnder modulators （MZMs）. The first MZM,biased at minimum transmission,is only used for the odd-order optical harmonic generation, and then by using a second MZM, biased at maximum transmission, all odd- order optical harmonics are suppressed. As an example,we consider a radio frequency （RF） at 10 GHz, which drives the MZMs; and a ram-wave signal at 60 GHz, i. e. a frequency sixupler, is obtained. The generated ram-wave signal is robust to fiber chromatic dispersion. The proposed technique is verified by experiments.
