Abstract
Side chain polymers were investigated for the realisation of nonlinear film and rib waveguides. Cyanobiphenyl and azo-chromophores have been studied as nonlinear optical side groups by measuring the nonlinear optical coefficients, the refractive indices and the transparency range. Periodically poled waveguides using electrode and Corona poling in combination with corrugated surfaces have been fabricated. First experience and results for the realisation of quasi-phase-matched NLO-waveguides for second-harmonic generation using these polymers are presented.
