We propose a method for controllable frequency line spacing soliton formation in a microresonator using two continuous-wave（CW） pumps with multi-free-spectral-range（FSR） spacing. The method we propose has better control over the amount and location of the solitons traveling in the cavity compared to the tuning pump method. We also find that by introducing a second pump with frequency N FSR from the first pump, solitons with N FSR comb spacing can be generated.展开更多
