| description | Fiber optical parametric amplifiers (FOPAs) operating based on four-wave mixing (FWM) are versatile devices
with increasing applications in optical communication systems. In this paper, the effects of dispersion fluctu�ations on the performance of bandwidth, ripple, parametric gain, and saturation power of a two-pump FOPA
based on four-wave and six-wave models are studied and compared. Coupled-amplitude equations representing
the non-degenerate FWM process in optical fiber are solved numerically to compute the parametric gain over the
communication wavelengths. The behaviors of the performance parameters are critically analyzed and compared
with different types of fluctuation strengths (or amplitudes) specified by the combinations of correlation length
(Lc) and fluctuation amplitude (σ). Based on the results, it was found that the flat gain bandwidth for the four-wave
model remains unchanged and is insensitive to the strengths of fluctuations. The gain ripples, however, get higher
as the fluctuation strengths increase. On the other hand, the flat gain bandwidths of the six-wave model are hardly
identified due to the tremendous and continuous ripples within the pump wavelengths. In addition, the minimum
parametric gain values for both four-wave and six-wave models reduce as the fluctuation strengths increase. Also,
the lowest value of parametric gain leads to the highest saturation power and vice versa. The dispersion fluctuations
affect the FWM process’s efficiency and deteriorate the overall amplifier performance, particularly for the six-wave
model. The numerical analysis obtained via the six-wave model is especially useful since this model closely matches
with practical circumstances. |
