SECOND HARMONIC GENERATION IN POLYMERS WITH IMPROVED TRANSPARENCY AND WAVEGUIDES FOR QUASI-PHASE-MATCHING

摘要

Side chain polymers were investigated for the realisation of nonlinear film and rib waveguides. Cya-nobiphenyl chromophores and azo-dyes have been studied as nonlinear optical side groups by measuring the nonlinear optical coefficients, the refractive indices and the transparency range. First experience and results for the realisation of quasi-phase-matched NLO-waveguides for second-harmonic generation using these polymers are presented.
