摘要
A tunable photonic bandgap fiber filter was incorporated in an Er-doped superfluorescent fiber source to improve its mean wavelength thermal stability. This simple filter was able to successfully compensate the mean wavelength to less than 10 ppm from -40 degrees C to 70 degrees C. When the environmental temperature was controlled to +/- 0.5 degrees C, the superfluorescent fiber source (SFS) exhibited a long- term mean wavelength stability of +/- 1 ppm over 11 h. With 60-mW pump power at 974.2 nm, an optimal Er-doped fiber length of 8mwas found, and the final output power of the compensated SFS reached 8 mW.
