摘要：

We have demonstrated a polymeric electro-optic modulator based on a 1x2 Y-fed directional waveguide coupler. The symmetric geometry of the 1x2 Y-fed directional coupler provided the modulator unique characteristics of intrinsic 3dB operating point and two complementary output ends. A low switching voltage of 3.6V and a high extinction ratio of 26dB were obtained with the modulator operating at a wavelength of 1.34 mu m. The modulator was fabricated with a novel electro-optic (EO) polymer that was synthesized from polyurethane crosslinking with a chramophore.
