Comb-shaped polymers, comprised of hydrophilic backbones and dye-containing, hydrophobic side chains are fabricated into multilayered, polarized, noncentro-symmetric, thin films by means of Langmuir-Blodgett processing techniques. These films exhibit harmonic, generated by shining a laser through the film, increases quadratically with the number of layers of polymeric dye in the film.
