Paper Abstract

We report on a scheme for phase-matching second harmonic generation in polymer waveguides based on the use of anomalous dispersion to optimize Cerenkov phase matching. We have used the theoretical results of Hashizume et al. and Onda and Ito to design an optimum structure for phase-matched conversion. We have found that the use of anomalous dispersion in the design results in a 100-fold enhancement in the calculated conversion efficiency. This technique also overcomes the limitation of anomalous dispersion phase- matching which results from absorption at the second harmonic. Experiments are in progress to demonstrate these results.
