Coplanar-Electrode Measurement of Electro-Optic Coefficients in Poled Polymer Thin Films

Abstract

A coplanar electrode structure is introduced to measure the linear electro-optic (EO) effect of poled polymer thin films. The coplanar structure has advantages over the parallel plate structure in removing artifacts such as piezoelectric effect and electrostrictions. Optical geometry of coplanar electrode thin film setup is analyzed to find a relationship between the measured modulated intensity and microscopic molecular parameters. © 1995, Taylor & Francis Group, LLC.
