Corona Poling of Nonlinear Optical Molecule-Doped Polymer Glasses.
01 January 1987
The application of corona poling to orient nonlinear optical molecular dopants dissolved in a polymer matrix is reported. The apparatus and process are described along with preliminary measurements of the second harmonic coefficient and the electronic part of the electro-optic coefficient. A 2-3 fold increase in the coefficient over conventional electrode-poling is observed with Disperse Red 1 azo dye doped films. The coefficient decays to a steady state of half its original value as is observed in electrode poled films. In addition, two compounds containing cyanovinyl acceptors are introduced into films and corona poled. The measured coefficients are consistent with those expected from a linear model. Stable coefficients as large as 29x10 sup -12 m/V are obtained.
