摘要

We have investigated various conductive and non-conductive polymer materials suitable for use as cladding layers in nonlinear optic (NLO) polymer based opto-electronic devices. Out goal was to maximize the nonlinearity of the NLO core material, while minimizing the total poling voltage and minimizing the absorption loss. Using a cladding material that is more conductive than the NLO core material, the majority of the applied poling voltage is dropped across the core, realizing a maximum EO coefficient with minimum applied poling voltage. We found, however, that there are tradeoffs between absorption loss, conductivity, refractive index, materials processability and materials compatibility when using off-the-shelf materials. Results are presented for a 3-layer device structures using a conductive polymer material for both the top and bottom cladding layers.
