Abstract
Systems and methods for a tunable radio frequency synthesizer utilizing optical frequency combs are provided. In one embodiment, an RF signal generator comprises: an SBS pump laser segment including a first and second SBS pump laser each generating SBS laser light at different respective frequencies; a TE/TM dual comb resonator comprising a comb optical resonator coupled to the first and second SBS pump lasers, wherein the comb optical resonator generates a pair of counter-propagating optical frequency combs of different polarities from the SBS laser light; a filter resonator segment configured to provide feedback to the TE/TM dual comb resonator to lock a relative position of the pair of counter-propagating optical frequency combs, the filter resonator comprising a tunable optical filter to output a discrete tuned RF signal output based on a comb line pair that includes a single comb line from each of the pair of counter-propagating optical frequency combs.
