摘　　要：Chip-based frequency combs have attracted increasing attention in recent years due to the advantages of small size,integrability, low power consumption, and large re-frequency range. Continuous and deterministic generation of optical frequency combs is critical for the development of diverse applications. In this work, an integrated design of a computer-program-controlled optical frequency comb generation scheme is developed, whereby the optical frequency comb generation and monitoring units are housed inside an aluminum box. Through this improvement, an optical frequency comb with a free spectral range(FSR) of 100.3 GHz can be generated and maintained continuously for a duration of >48 h.It is varied that the control method is highly effective during 1000 startup tests. With statistical analysis, the startup probability and mean time of the single-soliton state is 100% and as short as 1.5 s, respectively. Besides, chaotic states with a startup probability of 100% and a mean time of 0.31 s are also generated with the same program. The self-injection-locked generation method is still less stable and shorter in duration, and it requires a different state for each generation, which is capable of generating the Kerr optical frequency comb more consistently and more rapidly.
