We present a comprehensive numerical investigation of the polarization dynamics of dissipative-soliton-resonance (DSR) pulses in a passively mode-locked Yb-doped fiber laser With a nonlinear optical loop mirror (NOLM). In our simulations, the NOLM's saturable absorption effect is modeled by its transmission function. Depending on the strength of cavity birefringence; various types of vector DSR pulses; including the polarization-locked DSR (PL-DSR), the polarization rotation-locked DSR (PRL-DSR), and the group Velocity-locked DSR (GVL-DSR) states are obtained in the laser cavity. The characteristics of these vector DSR pulses are shown. We also analyze the polarization evolution and internal polarization dynamics of PRL-DSR pulses Within the cavity. Our simulation results offer insight into the vector nature of DSR pulses in polarization-insensitive mode-locked fiber lasers.
