Poled film of 2-methyl-4-nitroaniline (MNA) and poly(methyl methacrylate) is prepared. Poling effects of MNA molecular alignments are observed by reducing the absorption spectrum and increasing the refractive index of the film. Phase-matched second harmonic generation (SHG) is achieved using the mode dispersion relation of the optical waveguide with an estimated SHG conversion efficiency of 7.4 x 10(-3) % in the waveguide.
