Abstract

Much progress has been made in the development of electro-optic (EO) polymers for guided-wave device applications.^1-4 Reported here are techniques that use the device electrodes directly for poling. A TE device is demonstrated in which surface electrodes were used to provide alignment parallel to the substrate surface requiring no ground plane. A novel TM device structure was also demonstrated in which a push-pull electrode was poled with counteraligned fields so that the signal field is coaligned, thus requiring only a single voltage source. This development permits polymeric devices the same advantages as LiNbO₃.
