Abstract

The effects of optical feedback on the characteristics of a double pass backward (DPB) superfluorescent fiber source (SFS) are demonstrated and compared to those of the single pass backward (SPB) SFS. The major effects of the optical feedback are the formation of resonance cavity for a DPB SFS and the reduction of output power for an SPB one. An isolator with an isolation loss larger than 50 dB should be used for both backward SFSs to maintain a stable mean wavelength operation, large output power and broad linewidths.
