Abstract
Systems and methods in accordance with embodiments of the invention implement all-microwave stabilized microresonator-based optical frequency comb. In one embodiment, an all-microwave stabilized microresonator-based optical frequency comb includes: an optical pump configured to generate pulses of light; a microresonator including an input configured to receive pulses generated by an optical pump and an output configured to generate an optical frequency comb signal characterized by frep and ξ; where frep describes spacing of frequency components in the optical frequency comb; where the optical frequency comb includes a primary comb and a plurality of subcombs and ξ is a frequency offset between subcombs; and two phase locked loops that phase lock frep and ξ to low noise microwave oscillators by modulating output power and pump frequency of the optical pump.
