Anomalous dispersion phase-matched second harmonic generation in poled polymer waveguides

We demonstrate anomalous dispersion phase-matched second harmonic generation in a poled polymer waveguide. Phase-matching was achieved between lowest order fundamental and harmonic modes. TMwo to TM2wo, at a fundamental wavelength of 815 nm over a propagation length of 32 micrometers . The maximum conversion efficiency was (eta) exp equals 39%/Wcm2, in good agreement with theory. Methods to further enhance the conversion efficiency using a combination of phase-matching techniques are also discussed.
