The purpose of this research is generation of high quality and modulated signals in the frequency range of millimeter and terahertz by using Mach-Zehnder-modulator-based flat comb generator. This method relies on the frequency accuracy and stability of the optical comb source. By evaluation of generated signals, this method can generate millimeter and terahertz waves with extremely narrow linewidth and low phase noise. Furthermore, generation of multi-carrier signals was demonstrated.
