Abstract
For the thermal stability of mean wavelength of erbium-doped super-fluorescent fiber source (SFS), particularly, from a different viewpoint, we analyzed the variation of spectrum of SFS at different temperature and wavelength range. Firstly, the spectrum of a SFS at 10 °C is selected as a standard data (STDD), then at the different temperatures from -40 °C to +60 °C (10 °C per step), the spectrums subtract the STDD for the spectral temperature dependent instability. It is found that the variation of spectrum from short wavelength to long wavelength can be divided into three regions. In the middle wavelength region from 1540nm to 1565nm, the dBm values of the spectrum are decreased with increasing temperature, and with wavelength-flattened characteristics. On the other hand, at the short and long wavelength region, the dBm values of the spectrum change inversely with temperature, and the variations are larger than that of the middle region. Based on this characteristics, we design a new configuration of SFS, the mean-wavelength stability can be achieved 2.10ppm/mA and 1.75ppm/ °C in the range of pump current from 100mAto 250mA and in the range of temperature from -40 to +60 °C, respectively.
