Paper Abstract

We study the effects of the induced third-order nonlinearity on backward second-harmonic generation in Penodically Poled Lithium Niobate (PPLN). We show that self-phase and cross-phase modulation terms induced by a proper engineering of the domain length can compete with intrinsic quadratic nonlinearity enriching the dynamics of the system. In particular it allows for self oscillation even with vanishing second-harmonic input.
