  The presence of refractive index fluctuations in an optical medium can result
in the generation of optical rogue waves. Using numerical simulations and
statistical analysis, we have shown that the probability of optical rogue waves
increases in the presence of spatial correlations in the fluctuations of the
refractive index. We have analyzed the impact of the magnitude and the spatial
correlation length of these fluctuations on the probability of optical rogue
wave generation.
