Fundamental studies have been conducted on the factors which determined chromophore hyperpolarizability to optical loss ratio and which determined chromophore interaction leading to attenuation of electric field poling induced electro optical activity. These studies have lead to a new generation of electro-optic materials exceeding for the first time the performance of inorganic electro optic materials. Lattice hardening chemistry used to lock-in poling-induced electro-optic activity has been systematically investigated. Fundamental studies of poling-induced optical loss have been conducted. A new technique for processing polymer buried channel waveguides, multi-color photolithography, has been introduced.
