Thin films of polymer doped with nonlinear optical organic dye, Disperse Red 1, at thickness of 1 to 2 micrometers, were prepared and studied. In order to induce an axial and orientational alignment of dye molecules within polymer matrix, a contact electric field poling was used. By this process the inherent inversion symmetry in the polymer matrix was eliminated to achieve the desired macroscopic second order nonlinear optical response. With a method based on spectroscopy, poling process and parameters related to orientation were studied. Different parameters such as temperature and residual solvent effects and also temporal and spatial dependencies were investigated and analyzed.
