Experimental Investigation on Near Gaussian-shaped Spectrum Erbium-Doped Fiber Super-flourescent Source in Double-pass Forward Configuration
The on near Gaussian-shaped spectrum Erbium-doped fiber super-flourescent source was studied. The self-coherence function of Gaussian-shaped spectrum and the change of mean wavelength under different temperatures were theoretically analyzed. Using the double-pass forward configuration, the Gaussian-shaped spectrum was obtained with certain Erbium-doped fiber length. Meanwhile, pump powers could be adjusted to optimize the intrinsic thermal coefficient of Erbium-doped fiber. Finally, under the condition with erbium-doped fiber length of 10.05 m, LD power of 172 mW, the whole optical path (except pumping LD and the driving) in the environmental temperature from -40 ℃ to 60 ℃, the near Gaussian-shaped spectrum Erbium-doped fiber source with 66.651 ppm mean wavelength stability was obtained.
