Erbium ytterbium co-doped super-fluorescent fiber source(EYD-SFS) has been simulated by a theoretical model based on rate equations and power transfer equations. The output performances of four basic structures of EYD-SFS have been expressed, and it indicated that the DPF structure is a preferable structure. The dependence of output power, mean wavelength and bandwidth stability on the pump fiber length and the concentration of Er3~+ and Yb3~+ have also been studied. The results indicated with a proper doping concentration of Er3~+ and Yb3~+ of 6.0 1026ions/m~3 and 1.0 1027ions/m~3, the optimal gain fiber length is 3.6 cm. In this condition, good performances of DPF structure of EYD-SFS have been achieved.
