Abstract

We report the dependence of the mean wavelength of Er-doped superfluorescent fiber sources on temperature, pump wavelength, and pump power. In particular, we measure an intrinsic temperature coefficient of between −2 and +8 parts in 10⁶ (ppm) per degree Celsius depending on pump wavelength, pump power, and fiber length. Additionally, we report a pump wavelength dependence that is symmetrical about the peak pump absorption wavelength (near 976 nm) and a decrease in mean wavelength with pump power with a slope of between 0 and −93 ppm/mW.
