Paper Abstract

A masterly two-stage structure for Erbium-doped superfluorescent fiber source (EDSFS) with high output power and broadband amplified spontaneous emission (ASE) spectrally flattened in both C-band and L-band is presented in this paper. Thereinto, the L-band ASE is generated in the first forward-pumping double-pass stage, and amplified in the second backward-pumping single-pass stage, where a high-power C-band ASE is simultaneously generated. The output ASE with a power of 16dBm and 3dB bandwidth over 61nm is obtained by simulations with the simple structure without any filter, by suitably choosing the structure parameters of the two-stage EDSFS, such as the lengths of Erbium-doped fibers (EDF) in the two stages and the beam splitting ratio of pump powers of the two stages.
