A simple multi-wavelength passively Q-switched Erbium-doped fiber laser is demonstrated using graphene based saturable absorber, which is prepared using polyethylene oxide as a host polymer. The multi-wavelength operation is achieved based on nonlinear polarization rotation effect by incorporating 5...
