Abstract:

The following objectives were defined and pursued 1 Synthesis of chromophores characterized by large hyperpolarizability and good thermal stability, 2 covalent coupling of nonlinear optical chromophores to polymer matrices, 3 lattice hardening reactions which permit locking-in of electric field poling-induced macroscopic noncentrosymmetric order, 4 definition of mechanisms of optical nonlinearity and development of improved instrumentation to effect such characterization, 5 exploration of methods of enhancing optical nonlinearity and electromagnetic field intensities within-materials e.g., exploration of cascading effects and morphological resonances. Substantial success was achieved in each of these areas with more than sixty publications resulting from AFOSR support. Electro-optic modulation, Directional couplers, Optical memories, Waveguide amplifiers, Room temperature spectral hole burning, DEC Chromophores, Femtosecond spectroscopy
