N2 - In this paper, we repot on generation of THz waves with high accuracy and precise controllability of the frequency using a photonic down-conversion technique. A 2.5 THz-spanned optical comb signal was generated by a combination of a Mach-Zehnder-modulator-based flat comb generator and a dispersion-flattened dispersion-decreasing fiber. By mixing a two-tone signal extracted from the comb signal, THz signals have generated, in which the C/N ratio of them was greater than 30dB.
