Frequency doubling in poled polymers using anomalous dispersion phase-matching

We report on a second harmonic generation in a poled polymer waveguide using anomalous dispersion phase-matching. Blue light was produced by phase-matching the lowest order fundamental and harmonic modes over a distance of 32 micrometers . The experimental conversion efficiency was n equals 1.2 X 10-4, in agreement with theory. Additionally, we discuss a method of enhancing the conversion efficiency for second harmonic generation using anomalous dispersion phase-matching to optimize Cerenkov second harmonic generation. Our modeling shows that a combination of phase-matching techniques creates largest conversion efficiencies and reduces critical fabrication requirements of the individual phase-matching techniques.
