The objective of this research is to bring the demonstrated advantages of the electrooptic polymers into use in photonic devices and systems. In this report we demonstrate a waveguide taper section for improved mode matching between the traveling wave electrooptic polymer modulator and input and output fibers. The taper section increases the waveguide mode and reduces the fiber coupling loss at each end by approximately 2 dB. The design is compatible with current modulator design. We also report on a polymer bleaching process for balancing the outputs of a waveguide Y junction. This process is used to increase the extinction ratio of a polymer Mach Zehnder modulator.
