Broadband parametric processes in quadratic nonlinear photonic crystals

• We develop a general model, based on a (2+1)D unidirectional pulse propagation equation, for describing broadband noncollinear parametric interactions in two-dimensional quadratic lattices. We apply it to the analysis of twin-beam optical parametric generation in hexagonally poled LiTaO<inf>3</inf>, gaining further insights into experimental observations.
