We are examining a variety of novel high temperature stable polymers as new materials for second order nonlinear optical NLO and photorefractive devices. Current polymers have sufficient optical signal generated by available chromophores, but are not practical for device applications because of limitations in the temporal stability of the dopant orientation in the polymer caused by poor thermal stability of the host. This is a novel approach for developing a new class of photonic materials with superior thermal and temporal stability and is the first attempt to design a second order NLO polymer with controllable, tailorable local physical and electrical properties. A second, equally important goal is to understand the basic polymer physics controlling the thermal and temporal stability of the optical chromophore orientation. This will determine not only the overall efficiency of the materials for device applications, but will generate substantial information about mobility in high temperature stable polymer systems.
