Abstract

Organic electro-optic polymer has low dielectric constant and high electro-optic coefficient, which is one of the perfect materials for making modulators with low loss and high bandwidth. In this paper, we synthesized a novel chromophore based on the 4-(diethylamino) salicylaldehyde electron donor and the rigid isolated benzyl group. Based on the innovative chormophore, we designed low loss Mach-Zehnder interference modulators with 3dB bandwidth 50GHz using tapered waveguides and coplanar waveguide electrodes as well as micro-strip electrodes. Performance parameters of the modulators were detailed analyzed and two microwave driven electrodes were compared.
