Abstract
An tunable optical frequency comb source includes a linear waveguide having an input leg to couple to a pump laser. A ring microresonator is evanescently coupled to the linear waveguide. The microresonator includes a ring shaped waveguide having a core material with a nonlinear refractive index to provide four-wave mixing to generate a cascade of independent laser beams at frequencies corresponding to the longitudinal modes of the microresonator.
