1. A frequency comb generator, comprising:

  • a semiconductor outputting a frequency comb in response to frequency mixing of an optical field and a terahertz field in the semiconductor, wherein;

    the semiconductor has a bandstructure, including a valence band and a conduction band, such that the semiconductor outputs the frequency comb in response to the terahertz field driving electrons and holes in the bandstructure, after the optical field excites the electrons into the conduction band and excites the holes into the valence band.
