Abstract

The aim of this work is to investigate the optical parametric oscillation (OPO) in 2D nonlinear photonic crystals [1]. Periodically poled lithium tantalate (2D-PPLT) crystals are designed to allow multiple reciprocal lattice vectors contribution to the quasi-phase matching (QPM) scheme [2]. We are particularly interested in the effect of the multi-wavelength parametric generation performed by the 2D nonlinear photonic crystal to achieve a multi-resonant optical parametric oscillation [3]. The performances of 2D-OPO are studied in terms of generation efficiency and multi-wavelength generation.
