Abstract
We have demonstrated multi-wavelength generation in a nonlinear photonic crystals of lithium tantalate. The optical parametric generation leads to second harmonic generation, sum-frequency generation and other frequency conversion in a cascade process. These conversions are assisted by all the optical nonlinear process involving χ(2) and achieved by satisfying the quasi-phase matching conditions.
