主　　题：Type-II micro-comb generation a filter-driven four wave mixing laser 

摘      要：We experimentally demonstrate the generation of highly coherent Type-II micro-combs based on a microresonator nested in a fiber cavity loop, known as the filter-driven four wave mixing （FD-FWM） laser scheme. In this system, the frequency spacing of the comb can be adjusted to integer multiples of the free-spectral range （FSR） of the nested mlcro-resonator by properly tuning the fiber cavity length. Sub-comb lines with single FSR spacing around the primary comb lines can be generated. Such a spectral emission is known as a ＂Type-II comb＂. Our system achieves a fully coherent output. This behavior is verified by numerical simulations. This study represents an important step forward in controlling and manipulating the dynamics of an FD-FWM laser.
