The broadband generated by the inclusion of dispersion shifted fiber, highly nonlinear fiber, and their combinations in the cavity of a filterless erbium-doped fiber ring laser is experimentally studied in this work. The gain spectrum of erbium-doped fiber and the nonlinear effects due to low-dispersion specialty fibers govern the spectral broadening. The experimental results are compared and analyzed with the aid of the dependence of the spectrum on the input pump power provided to the gain medium.
