Abstract

The impact of random dispersion fluctuations on the gain and saturation behavior of a one-pump fiber optical parametric amplifier (1-P FOPA) in the presence of fourth-order dispersion coefficient $({\mathit{\beta }}_4)$ is investigated. Three coupled amplitude equations with fiber losses are solved numerically for the calculation of the pump, signal, and idler. The performances of 1-P FOPA are also analyzed with variation of dispersion fluctuation amplitude $(\mathbf{\sigma })$ and correlation length $({\mathbf{L}}_{\mathbf{c}})$. Based on the numerical results, it is found that the gain spectra and saturation curves exhibit some differences when ${\mathit{\beta }}_4$ is considered. In comparison with the case where ${\mathit{\beta }}_4$ is ignored, the peak gain remains the same, but the 3 dB bandwidth increases when ${\mathit{\beta }}_4$ exists. Another notable difference is that the saturation power is shifted to lower or higher values, depending on the $\mathbf{\sigma }$ and ${\mathbf{L}}_{\mathbf{c}}$ parameters. In general, the peak gain reduces as $\mathbf{\sigma }$ increases, and the peak gain reduction is greater for the case of shorter ${\mathbf{L}}_{\mathbf{c}}$. The numerical analysis is probably useful, especially for the case where the signal wavelength is detuned far from the pump wavelength.
