Simulation of nonlinear Schrödinger equation is presented, for a dispersive chiral media, with Kerr-type non linearity. Spatial chirality effects is considered through the Born-Fedorov formalism. Results obtained, by means of Fourier method, show the chirality effects over circular and mixed polarized solitons pulses in an anisotropic cubic media. Numerical simulation results show that right hand circulary polarized solitons are more stable that left hand polarized, when the chirality factor increases. For this later case, a mode conversion is observed for N=1 to N=2 if the chirality factor has an adequate value. For coupled modes the chirality factor allows the existence of elliptically polarized modes together with fundamental modes.
