An efficient erbium doped superfluorescent fiber source (SFS) is proposed by comparing the different configurations in the C and L band regions. The flat spectrum of the source over a wide range is examined in various arrangements. The suggested array employed is based on loop mirror and double-pass bidirectional sources for making a flat and stable amplified spontaneous emission power. The maximum power of each of the two 980 nm laser diodes was optimized at 180 mW. Furthermore, the place effect of the laser diode's power near the output port was demonstrated for the first time. Finally, the optimum flattening manner of this ASE source was achieved in 185-50 mW pump powers and 32 mW total power over the 1525-1605 nm region (C+L band). © 2013 Astro Ltd.
