摘要

A superfluorescent fiber source (SFS) based on an Er3+-doped photonic crystal fiber (EDPCF) is reported.Owing to the temperature insensitivity of the EDPCF,we show that it is possible to improve the mean wavelength stability of an SFS.Using single-backward configuration,the EDPCF SFS mean wavelength variation at temperatures from -40℃ to 60℃ is less than 100ppm,indicating that the thermal coefficient of the EDPCF is smaller than 1 ppm/℃ and 3-6 times smaller than those of two conventional Er3+-doped fibers under the same experimental conditions.The best performance of the EDPCF-based SFS is obtained between 0℃ and 60℃,at which the change in the mean wavelength is only 17.445 ppm.
