The VSMs are generated in a passively mode-locked fiber laser, and their time separations can be flexibly adjusted by applying different birefringence parameters. Moreover, along the laser output port, the generated VSMs can be flexibly manipulated by a projected module consisting of a polarization controller and an inline polarization beam splitter. Thus, a 2-2-2 and 2-2-4 type VSMs could be obtained separately. Moreover, we have verified that the vector soliton separation is the key parameter that determines the formation of obtained VSMs. These simulation results would greatly enrich the understanding of soliton dynamics and provide inspiration for experimental researches. 收起
