| 摘 要： | 提出并理论分析和实验验证了一种新的产生毫米波的六倍频技术。该方法采用两个相同串联的双电极驱动马赫-曾德尔电光调制器(MZM),调节第一个MZM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,调节第二个MZM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。实验结果显示,采用10 GHz的射频(RF)信号驱动这两台MZM后,输出60 GHz的毫米波信号,实现了六倍频。通过测量输出的信号性能指标并与未使用带通光滤波器方案作比较得出经过50 km光纤传输后,输出信号受到色散的影响小。

| Abstract: | A novel technique for the generation of millimeter-wave(mm-wave),i.e.,frequency sextupling technique,is theoretically analyzed and experimentally demonstrated.The proposed technique is comprised of two cascaded dual-electrode Mach-Zehnder modulators(MZMs).The first MZM,biased at the minimum transmission,is only used for odd-order optical harmonic generation,and then a second MZM,biased at the maximum transmission,suppresses all odd-order optical harmonics.As an example,a 10 GHz radio frequency(RF) signal,wh... |
