Abstract : We are examining a variety of novel high temperature stable polymers as new materials for second order nonlinear optical (NLO) device applications and modelling the rotational Brownian dynamics of chromophore orientation. Current polymers have sufficient optical signal generated by available chromophores, but are not practical for devices because of limitations in the temporal and thermal stability of the active chromophore orientation in the polymer matrix. This experimental and theoretical approach for developing a new class of photonic materials with superior thermal and temporal stability is a first attempt to design second order NLO polymer with controllable, tailorable local physical and electrical properties. A second, equally important goal is to theoretically and experimentally 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 local mobility in high temperature stable polymers. jg p.8
