Abstract
The electric field induced dynamic phase-matching of SHG waveguide was first demonstrated using a main chain type NLO polymer. The optimum phase-matching thickness was controlled by applied an electric field to polymer waveguide. The effective phase-matching thickness variation induced by poling is about 0.025 micrometers which is 6 times larger than FWHM of phase-matching thickness in conventional slab waveguide. The efficient phase-matched SHG was observed from taperless slab waveguide. No decay of SH conversion efficiency is observed in the presence of electric field.
