Abstract
Erbium-doped superfluorescent fiber sources (SFS) in the standard forward, backward, and double-pass configurations exhibit significant dependencies of the output mean wavelength on the pump state of polarization. This is due largely to polarization-dependent gain (PDG) and gives rise to long-term drifts of the source output mean wavelength through changes in the fiber birefringence. By replacing the mirror in a double- pass source with a Faraday rotator mirror (FRM), the magnitude of the SFS mean wavelength variations due to pump polarization changes is reduced by a factor of 5 - 40, depending on source design parameters. Simulation results as well as experimental demonstration of the Faraday double-pass SFS are discussed in this paper. We measured 10 parts per million for the polarization-related mean-wavelength variations in this source, approaching the requirement for high-accuracy fiber gyros.
