Abstract
Periodically poled ferroelectrics have recently been developed as flexible materials for tailored nonlinear optics. The periodic domain reversal in the crystal corresponds to a material with modulated sign of the nonlinearity, which will compensate for phase velocity mismatch between the interacting waves through an artificial k-vector. This allows the material to be used for quasi-phasematched nonlinear wavelength conversion.
