 This paper discusses the generation of broadband optical frequency combs using dissipative solitons in quasi-phase matched micro-resonators. It explores the soliton and breather regimes in both phase matched and slightly phase mismatched resonators. In phase matched resonators, the soliton regime is observed to have a narrower spectrum than the phase mismatched case, while the latter exhibits higher order harmonic generation.
