Abstract A technique is used to design the spectra in erbium doped superfluorescent fiber source experimentally and theoretically. In an erbium doped fiber with a 10m length and 300ppm concentration, a line width of about 42nm and high mean wavelength stability (<0.lppm/K, <0.2ppm/mW) were obtained by means of a suitable population distribution, and adjusting the ratio of backward to forward pump power. Also, its thermal characteristic is studied. These results will improve the performance of fiber optical gyroscope and fiber sensors, and will be applied in erbium doped fiber amplifier with flattening gain.
