Impact of dispersion fluctuations on the gain spectrum and the saturation behavior of one-pump fiber optical parametric amplifiers

In this article for the first time, the impact of dispersion fluctuations on the gain spectrum and saturation behavior of one-pump fiber optical parametric amplifiers (1-P FOPA) is investigated. By considering the dispersion fluctuations as a stochastic process and solving the coupled amplitude equations, the saturation curves and the gain spectra of 1-P FOPAs are simulated for different fluctuations parameters including the standard deviation and the correlation length. Results show that the saturation power and the gain spectrum are considerably changed in presence of dispersion fluctuations in comparison with the case when dispersion fluctuations are ignored.
