TLDR
Transverse patterning of periodic gratings for quasi-phase matching (QPM) has been used to increase the tuning range of devices (through fanned gratings), to shape the amplitude profile of an interacting beam, and to create two-dimensional periodic QPM structures (nonlinear photonic crystals) for efficient noncollinear mixing as mentioned in this paper.Abstract:
Summary from only given. Transverse patterning of periodic gratings for quasi-phase- matching (QPM) has been used to increase the tuning range of devices (through fanned gratings), to shape the amplitude profile of an interacting beam, and to create two-dimensional periodic QPM structures (nonlinear photonic crystals) for efficient noncollinear mixing.read more

Generation of Bessel beams by parametric frequency doubling in annular nonlinear periodic structures.
TL;DR: It is demonstrated that the parametric conversion of the Gaussian fundamental beam propagating along the axis of the annular structure leads to the axial emission of the second-harmonic field in the form of the radially polarized first-order Bessel beam.
