中文摘要：

针对备受国际通信行业关注的接入网成本压缩问题,本文研究了ToF系统中4倍频产生0.1THz光载太赫兹信号的新方法,并对该方案进行了详细的特性分析。本文提出的太赫兹波产生方法,既满足超宽带,又满足系统稳定性,最大程度降低了成本。该方法根据马赫曾德尔调制器的响应函数,采用数学理论推导和仿真实验相结合的方法,提出了干扰信号抑制比的重要参数,阐明了串联后的调制器输出信号的倍频原理和模拟实验结果分析。结果表明,在如下参数区间内△Ф（87°,93°）∪（267°,273°）、DCbias（1.31V,1.68V）,系统可以保证产生性能良好的4倍频信号,为器件的研究提供可靠依据。

英文摘要：

A novel scheme for 0.1 THz optical Tera-Hz signal generation in ToF（THz over Fiber） system is proposed and analyzed.The ToF system used widely in broadband access networks has more stringent requirements on the cost,while the scheme proposed can reduce the system costs.The scheme using frequency quadruplication is based on two Mach-Zender modulators in a certain parameter setting,and we clarify the frequency-multiplication principle from the perspective of both mathematics and physics and the operation principle of Mach-Zender modulator.The condition of the side-band generation and the method for suppressing the band are investigated,and the parameters of suppression ratio are obtained.Furthermore,the tolerance range of the device parameters in a certain suppression ratio is studied,in order to provide reliable basis for the study of device.
