Multi-directional erenkov second harmonic generation in two-dimensional nonlinear photonic crystal. Academic Article

abstract

• We study erenkov-type second-harmonic generation in a two-dimensional quasi-periodically poled LiNbO3 crystal. We employ a new geometry of interaction to observe simultaneous emission of multi-directional nonlinear erenkov radiation with comparable intensities. This opens a way to control the angle of erenkov emission by tailoring the nonlinearity of the material, which is otherwise intrinsically defined by dielectric constants of the medium and their dispersion.
