Simulation of key parameters of dual soliton microcombs ranging system with high repetition rate

The asynchronous optical sampling (ASOPS) ranging method using dual optical frequency combs (OFCs) has high measurement accuracy and fast measurement speed, is has been widely used in precision manufacturing, aerospace and scientific research. In recent years, with the development of photonic integration technology, the on-chip soliton microcomb technology has gradually matured. Microcomb has the advantages of small size, high repetition rate, great integration, and system stability, providing an ideal light source for ranging. This paper simulates on the key parameters of dual soliton microcombs ranging system with high repetition rate. The ranging model and numerical simulation method based on soliton microcomb are proposed, the effects of different repetition rate and repetition rate different on ranging accuracy are compared. The optimal parameters of soliton microcomb are obtained.
