Abstract:

The objective of the research performed was 1 development of electrooptic polymers which are usable in the visible, 2 use of sol-gel chemistry to improve on processability and bulk characteristics for waveguide applications, and 3 introduction of multifunctionality by composite approach. These objectives were met. For second-order nonlinearity needed for electrooptic effects, we had great success in the design of new types of chromophores with enhanced X2 and transparency in the visible. Our unique contributions are 1 inorganicorganic composites for nonlinear optics 2 successful poling of molecular-ionic polymers with high nonlinearity 3 novel processing to produce poled sol-gel silicatitania doped with electrooptic chromophores 4 planar optical waveguides using sol-gel processing and 5 combination of electrooptic function with photoconductivity to produce photorefractive polymers with a figure of merit comparable to that of existing inorganic photorefractive systems. The Langmuir-Blodgett method of film deposition was also investigated. The advantage of this method is that it provides a higher order parameter than a poled structure.
