High-Stability and Broad-Band Erbium-Doped Superfluorescent Fiber Source

Erbium doped superfluorescent fiber sources (SFS) pumped near 980 nm in double pass backward (DPB) configuration have been characterized through theoretical simulation. The results indicate that for a DPB SFS with a reflector of any reflectance, the pump power independent mean wavelength operation can always be achieved by properly adjusting the erbium doped fiber (EDF) length. In the case of high stable mean wavelength operation, the DPB SFS with the optimized reflector has a linewidth and pump efficiency obviously larger than SFSs in other configurations.
