Abstract
By photomixing of optical two-tone signals, which was extracted from an optical comb signal generated by a Mach-Zehnder-modulator-based flat comb generator (MZ-FCG), generation of cw-THz signal up to 700 GHz was demonstrated. In this system, the frequency accuracy of the THz signal is decided by that of the rf signal driving the MZ-FCG, so that it is expected that the generated THz signal has extremely high frequency accuracy.
