摘　　要：This paper proposes a mode-locked fber laser based on graphene-coated microfber.The total length of the fber laser resonant cavity is 31.34 m.Under the condition of stable output of bright-dark soliton pairs from the fber laser,dual-wavelength tuning is realized by adjusting the polarization controller(PC),and the wavelength tuning range is 11 nm.Furthermore,the efects of polarization states on bright-dark solitons are studied.It is demonstrated that the mode-locking state can be switched between conventional solitons and bright-dark solitons in the graphene mode-locked fber laser.Bright-dark soliton pairs with diferent shapes and nanosecond pulse width can be obtained by adjusting the PC and pump power.
