Dissipative Kerr Soliton (DKS), which uses Kerr nonlinearity to mode lock optical frequency comb occured from Four Wave Mixing(FWM) process in a microresonator, was experimentally shown and has been widely studied in recent years. One of its researching field is soliton crystal, which has narrow and stable temporal distribution in a time domain. Here, we suggest a method of generating soliton crystals with designable optical potential field using coherent multi-wavelength light source, which allows selective approach to desired defect states. For further reseach, combination with dn⁄dT engineering of the microresonator for the stabilization of soliton crystal states will be studied, expected to contribute to the development of new optical platform where behavior of soliton pulses inside the resonators can be experimented.
