The behavior of the polar orientational order parameter of two nonlinear optical (NLO) polymers is investigated using the second harmonic generation (SHG) and the refractive index/waveguide apparatus. The two NLO systems consist of a MNA/PMMA guest/host and a BCSC according main chain polymer. The MNA/PMMA results show the inadequacy of the independent dipole orientation model for the description of the electric field poling. The BCSC system illustrates the birefringence in the refractive index is not a necessary criterion for the second order nonlinear effect such as SHG.
