Abstract: 

IN THIS PAPER, WE STUDY THE DYNAMICS OF SPATIAL SOLITON OF NONLINEAR SCHRODINGER EQUATION IN INHOMOGENEOUS MEDIA WITH NONLINEAR KERR EFFECT. INITIALLY, BY INTRODNCING A SMALL PERTURBATION IN THE CANSTANT LINEAR INDEX OF REFRACTION OF THE MEDIA, THE INHOMOGENEOUS NONLINEAR SCHRODINGER EQUATION WAS OBTAINEAL. THEN, BY SOLING THE EQUATION, BOTH ANALYTICALLY AND NUMERICALLY THE BEHARIOR OF SOLITONS HAS BEEN INVESTIGATED UNDER THE IN FLUENCE OF DIFFERENT POTENTIALS, SUCH AS SIMPLE HARMONIC OSCILLATOR AND BARRIER POTENTIAL. IT IS SHOWN THAT THE BEHVIOR OF SOLITONS IN THIS MEDIA IS SIMILAR TO THAT OF THE CLASSICAL PARICLE MOVING IN AN EXTERNAL POTENTIAL RECOVERING THE NEWTON'S SECOND LAW.
