Abstract
Systems and methods which provide for the generation of optical frequency combs using a microring resonator optical frequency comb generator configuration are described. A microring resonator optical frequency comb generator configuration of embodiments comprises a plurality of fiber loop laser cavities and at least one microring cavity are utilized. For example, an optical frequency comb generator may include a first fiber loop laser cavity, a second fiber loop laser cavity that is symmetrical with the first fiber loop laser cavity, and a microring resonator that is coupled into both of the first and second fiber loop laser cavities. The microring resonator may be configured to provide a high quality factor, Q, value. The microring resonator of embodiments works together with optical bandpass filters and amplifiers in the multiple fiber loops to make the generated optical frequency comb stable and flexible.
