Abstract

Generation of millimeter (MM) and terahertz (THz) waves is important for wireless communications, perspective imaging, and so on. Since photonic technologies are advantageous to signal generation in such a high-frequency region as compared with electronics, several techniques based on photomixing have been developed [1]. In this way, an optical comb signal can be applied to a seed source [2]. A Mach-Zehnder-modulator-based flat comb generator [3] is good candidate for a comb source, because ultraflat comb signals can be stably generated. In this paper, we propose a generation method for multicarrier MM/THz signals using the MZ-FCG.
