Abstract: (1692 Views)
In this paper, a new nonlinear self-action effect called self-parametric amplification is simulated which manifests itself as an optical spectrum narrowing in normal dispersion fiber and leading to a very stable propagation with a distinctive spectral distribution. The narrowing results from inverse four-wave mixing resembling an effective parametric amplification of the central part of the spectrum by energy transfer from the spectral tails. Using an analytical solution, we simulate the inverse four-wave mixing process and examine the impact of different parameters such as fiber length, the initial spectrum width and input power on the output signal gain spectrum.
Keywords: Self-action effect, optical fiber, inverse four-wave mixing, self-parametric amplification
