Abstract
Second-harmonic generation and spectroscopic absorption measurements were made over a 15-month period to study the nonlinear-optical thin-film properties of an azo-dye attached polymer in which the dye chromophores were oriented by corona poling. Stable, resonance-enhanced values of the nonlinear optical coefficient d33 for the fundamental of 1.064 μm were as high as 68 pm/V. The stabilized order parameter, calculated from absorbance measurements, was found to be 0.51 for the chromophores.Keywords
