The two‐pump Four‐Wave‐Mixing (FWM) in the ring resonator promises more agile compact frequency comb generation than the traditional singe‐pump scheme regarding the convenient tuning of comb line space by modifying the two pumps’ space. The silicon‐nitride‐ring‐resonator‐based optical frequency comb generation system input with two pumps for the parametric process is simulated by an iterative process relying on the split‐step Fourier method. The influences of the coupling coefficient and pumps’ frequencies on the comb spanning are explained in terms of Q factor and resonance condition of the ring. © 2016 Wiley Periodicals, Inc.
