Quasi-phase-matching is now widely used for nonlinear optical frequency conversion, realizable in a material with its nonlinear optical coefficient modulated. The reciprocal vector of the structure is used for compensating the phase-mismatch between the interacting waves due to dispersion, whereas the ...
