I. Introduction
Dissipative soliton molecules can be generated in normal dispersion mode-locked fiber lasers due to a combination of fiber nonlinearity, intracavity dispersion, gain, loss, and spectral filtering [1], [2], [3]. Due to the sensitivity of dissipative systems, it is easy to manipulate the dissipative soliton molecules' output characteristics such as the number of pulses, and spectrum width, by changing the gain, nonlinearity, etc. [4], [5], [6]. In most soliton research, especially vector soliton molecules, the Hamiltonian system represented by conventional solitons is the most commonly studied system because of its simple physical model [7], [8], [9], [10]. However, the vector properties of more complex but better potential dissipative systems are rarely studied, so we choose the dissipative system to study the manipulation of vector soliton molecules to further demonstrate the more potential of dissipative systems compared to Hamiltonian systems.
