This study reports on the manipulation of vector soliton molecules (VSMs) based on the extra-cavity projected super-position technique, using numerical simulation results. The VSMs are generated and manipulated in a passively mode-locked fiber laser, providing flexible control over their time separations. The research emphasizes the importance of vector soliton separation in the formation of VSMs.
We report on the numerical simulation results of vector soliton molecules (VSMs) manipulation based on the extra-cavity projected super-position technique. 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.
