reportActive / Technical Report | Accession Number: ADA284983 | Open PDF

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 for 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.
