This paper we propose a new system design for optical frequency comb generator (OFCG) using PANDA ring resonator over terahertz span. This scheme can be generated high capacity frequency comb signal tens to hundreds of frequencies by using a Dark-Bright soliton pulse driven, so that we can obtain high capacity comb signal at the through and drop port, respectively. Our system can tune the rate and pulse width by driving signal or the ring parameter. In application, the proposed scheme can be recognized as a simple flexible and more stable for apply in advance circuit system.
