Abstract

In this Letter, we experimentally investigate multiwavelength parametric generation in two-dimensional second-order nonlinear photonic crystals. For this purpose, a 2D periodically poled lithium tantalate crystal with rectangular lattice was fabricated and characterized. We demonstrate multiple and simultaneous wavelength generation due to the contribution of different lattice vectors. Numerical simulations emphasize the agreement of our phase matching scheme with the experimental results and made it possible to assign the observed wavelengths to the reciprocal lattice vectors involved in the parametric generation process. Moreover, our results indicate that some signals are the result of the joint contribution of more than one lattice vector.
