Abstract:
Synthesis and processing of organic second-order nonlinear optical materials for fabrication of electro-optic modulators are discussed. Topics dealt with in order include (1) synthesis fo chromophores characterized by large hyperpolarizability and good thermal stability, (2) covalent coupling of nonlinear optical chromophores to polymer lattices, (3) lattice hardening reactions which permit locking-in of electric field poling-induced macroscopic noncentrosymmetric order, (4) fabrication of buried channel nonlinear optical waveguides by photochemical and reactive ion etching techniques, (5) coupling of nonlinear optical waveguides to fiber optic transmission lines and drive electronics, (6) prototype device fabrication and evaluation. Various device configurations are reviewed and recent advances in applications are discussed. Comparison is made between the performance of organic and inorganic materials for electro-optic modulation applications. (Author)
