Abstract
We report patterning studies of corona-poled aromatic rigid polymers bearing a nonlinear optical (NLO) chromophore as a side group. Patterned NLO domains were prepared on micropatterned electrodes by corona poling above Tg of the polymer. According to the results, the mode and extent of chromophore attachment play a significant role in the patterning of these domain-forming polymers, and the patterns can be controlled in principle by appropriately designing the materials and electrodes. The patterned domains exhibited a grating effect due to differential separations of domains of nearly uniform lateral size. This approach to control NLO the domain structures on patterned electrodes may be of importance for photonics applications.
