| 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...

| Abstract: | 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 mm-wave signal at 60 GHz,i.e.a frequency sixupler,is obtained.The generated mm-wave signal is robust to fiber chromatic dispersion.The proposed technique is verified by experiments. |
