Subharmonic entrainment (SHE) is a nonlinear synchronization phenomenon where an oscillation locks to an external periodic driving with a fraction of the oscillator frequency. This work introduces Vector Subharmonic Entrainment, demonstrating how the polarization of weak external signals can entrain internal fiber laser dynamics, offering control over mode-locking and polarization states.
