一种基于MZM的电信号任意倍频方法

文章提出一种使用马赫-曾德尔强度调制器(MZM)产生输入信号的任意倍频信号的方案,利用该方法不仅可以产生输入信号的偶数倍倍频信号,还可以产生输入信号的奇数倍信号.通过设置马赫-曾德尔强度调制器的直流偏置点在线性偏置点,产生了奇数倍信号,通过设置直流偏置点在特殊的非线性偏置点,产生了偶数倍信号.通过调节输入信号的幅度,可以得到想要的高阶倍频信号.理论分析和实验证实了该方案的可行性.

Electrical Signal Frequency Multiplication Method Based on Mach-Zehnder Modulator

In this article, proposed is a way to use Mach-Zehnder intensity modulator to generate electrical signals which are not only even times but also odd times frequency of the input signal. By setting the bias voltage of Mach-Zehnder modulator at linear biasing point, odd orders multiplication of frequency of the input signal is generated. And by setting the bias voltage of Mach-Zehnder modulator at even frequency multiplication point, even orders multiplications of frequency of the input signal is generated. In both circumstances mentioned above, the amplitude of the input signal can be adjusted to get the needed high order microwave signal. Theoretical analysis and experimental results prove the feasiblity of this method.
