Analysis of the Detuning Regulation of a Double-Pumped Microcavity

The detuning regulation of a double-pumped microcavity is investigated. In this paper, results show that one of the detuning parameters’ regulation facilitates dual-comb generation. When the other detuning parameter is selected appropriately, dual fields of solitons and Turing patterns generate simultaneously during the detuning. In this case, dual combs with a relatively large repeat frequency difference appear by use of a microcavity. Moreover, properly fast detuning is propitious for stable field evolutions, whereas slow detuning can lead to solitons and Turing patterns drift. Moreover, after the generation of solitons and Turing patterns in the detuning, the method of suddenly stabilizing the detuning parameter to a certain value is used to sustain or regulate the existing fields. When the fixed value of mutation is small, the coexistence of solitons and Turing patterns can be maintained all the time and the large variation value of the detuning parameter results in dual solitons in the microcavity. The results of this paper provide a new approach to excite dual combs taking advantage of a single microcavity.
