Abstract

We report on broadband comb generation using a combination of a Mach-Zehnder-modulator-based flat comb generator (MZ-FCG) and a dispersion-flattened dispersion-decreasing fiber (DF-DDF), as well as MMW signal generation using the MZ-FCG. For application of quantum cascade lasers operating in the THz range, phase-locking techniques are required to stabilize the frequency and the linewidth. Optical combs are good candidate for a reference source in the phase locking, because of the high stability and accuracy of the comb signals. Generation of a 110 GHz signal by photomixing of two-tone signal extracted from an optical comb signal has been demonstrated as a preliminary experiment.
