✦ Synopsis
By incorporating an isolator at an appropriate location, it is shown that it is possible to realize an efficient single-pass superfluorescent-doped fiber source with a major fraction of its emitted power in the forward direction. A theoretical model to estimate the performance of such a superfluorescent Ž . source SFS has been suggested and verified with experiments performed on an erbium-doped fiber in a novel pump bypass SFS configuration. Results on design issues such as optimum location of the isolator, pump power requirements, and spectral characteristics are also presented.
