Abstract: The disclosed technology, in one aspect, includes an optical comb generator device which includes a laser cavity that includes an optical gain material to provide an optical gain and an optical path to allow laser light to circulate inside the laser cavity; and a high-Q resonator optically coupled in the optical path inside the laser cavity so that the laser light generated and sustained inside the laser cavity is in optical resonance with the high-Q resonator to cause laser light stored inside the high-Q resonator to have an optical intensity above a four wave mixing threshold of the high-Q resonator to cause parametric four wave mixing so as to produce an optical comb of different optical frequencies.
