Changes in the pump polarization state are shown to have a large effect on the mean wavelength of erbium-doped superfluorescent fiber sources due to polarization-dependent gain. This effect causes long-term drift as the fiber birefringence in the source changes over time. By depolarizing the pump, this effect is reduced to under 3 ppm, the noise level of our instrument. A second depolarizer is used to compensate for polarization-dependent transmission of the other source components, namely the WDM coupler and the isolator. The resulting source is insensitive to drifts in the fiber birefringence due to environmental effects.
