We report on the comparison between experimental and simulation results for the polarization squeezing, anti-squeezing as well as squeezing angle generated using a 13.35m fused silica fiber. Based on the nonlinear Kerr effect (χ(3)) experienced by the ultra-short pulse in the fiber bright polarization squeezing was generated [1]. A first-principles simulation of the quantum time evolution in a many-body system for the polarization squeezing in optical fibers was also made by Joel F. Corney et al [2] which fits very well to the experiments. There they predicted that Raman effects will degrade the squeezing effect as the input energy surpasses the soliton energy. We investigate this prediction in experiment over a range of energies from 2 pJ to 170 pJ and achieve good agreement.
