Abstract

In this paper, we consider the phenomenon of modulation instability. Due to nonlinear phenomenon of self-phase modulation, the propagation of continuous wave beam is essentially unstable. For modulation instability, we plot various curves for gain spectra and find the maximum gain which shows the gain dependence on power, group velocity dispersion parameter and nonlinearity parameter.
