Abstract

We report on a series of tricyanovinylaniline chromophores for use as dopants in poled poly(methyl methacrylate) waveguides for anomalous-dispersion phase-matched second-harmonic generation. Second-harmonic-generation measurements as a function of mode index confirmed anomalous-dispersion phase-matching efficiencies as large as 245%/W cm2 over a propagation length of ∼35 µm. The waveguide coupling technique limited the interaction length. The photostability of the chromophores was measured directly and found to agree qualitatively with second-harmonic measurements over time and was found to be improved over previously reported materials. Prospects for obtaining efficient conversion by combining anomalous dispersion with Čerenkov phase matching are discussed.
