Abstract : Optical frequency combs find applications in optics, physics, precision spectroscopy and opto-electronics among others. The mode-locked laser is historically the system at the origin of these combs. More recently, in the quest for the miniaturization of optical frequency comb generators, micro-resonators and mini-resonators have emerged as attractive alternatives due to their compact nature as well as their mode selectivity and power enhancement properties. The work presented in this thesis is centered on the modeling of passive resonator based Kerr frequency combs. The first chapter of this thesis presents a state of the art of micro and mini Kerr frequency combs and puts forth the advantages of resonator-based platforms for the generation of optical frequency combs. The second chapter presents the model used to study passive optical resonators in the linear and non-linear regimes. The non-linear approach is based on an Ikeda map, allowing the study of Kerr comb formation in passive resonators. In the third chapter, Kerr frequency combs generated in an integrated resonator are presented. These results are compared to simulation results based on the model presented in the preceding chapter. The last chapter studies the impact of frequency-dependent access coupling parameters on the generation of Kerr frequency combs. Simulation results are presented, bringing to light the importance of the influence that these coupling parameters have on the combs generated in the resonator.
