Abstract
An optical frequency comb generator device is disclosed. In one implementation, the optical frequency comb generator device comprises a bus waveguide, at least a first optical ring resonator optically coupled to the bus waveguide, and at least a first grating located on the first optical ring resonator opposite from the bus waveguide. The first optical ring resonator and the first grating are configured to generate counter-propagating optical frequency combs that are offset from each other at a controllable bandwidth.
