Abstract

The mean-wavelength stability of broadband fiber source is analyzed: The model between the mean-wavelength and the pump optical power is revealed based on the theoretical and experimental study on the change of mean-wavelength under different pump optical power. To promote the temperature stability, a mean-wavelength control scheme is proposed based on the relation of mean-wavelength, pumping current and environment temperature. The output power was stabilized with a close-loop control technology by taking a adjustable attenuator. Prototype fiber source was made and tested. The Mean-wavelength stability 0.5×10^-6/°C and output power stability 3% within -45°C ~+70°C was achieved.
