Abstract
A new spectrum sliced multi-wavelength fiber source (MWFS) with no power loss is presented in this paper. The source is composed by a reflection Mach-Zehnder filter (RMZF) with double-pass backward superfluorescent fiber source (DPB SFS) configuration. The RMZF not only provides spectrum filtering but also provides the double-pass function. Multi-wavelength source with extinction ratios larger than 15 dB can easily be obtained over the total conventional band gain region with appropriate erbium-doped fiber (EDF) length and pump power. There is no power loss with the MWFS as compared to the original DPB SFS owning to the RMZF also provides the double-pass function. More than 50 channels of 0.57nm wavelength spacing between 1530nm-1560nm are obtained.
