Polymer-conductivity matching for efficient poling towards high second harmonic generation efficiency at 1.55 /spl mu/m

We have demonstrated the enhancement of the parallel plate poling efficiency by a factor of 3. We matched the best SHG FOM in polymer waveguides with a poling voltage three times smaller. Considering that we are still in a linear regime for the growth of the effective nonlinearity as a function of poling field, we can expect to gain at least an order of magnitude in the SHG efficiency by applying a larger voltage.
