The nonlinear crystals with modulated quadratic nonlinear coefficientsχ(2)are called quasi-phase-matching(QPM)materials,or optical *** concepts were first referred to by Armstrong et al and Ming et al several decades *** later extended the QPM from one dimension(1D)to 2D,and proposed the concept ofχ(2)photonic crystal in order to contrast and compare it with a regular photonic crystal having a periodic linear ***
