Abstract

Eigenmodes of three-wave interactions in second-order [χ⁽²⁾] nonlinear materials are explored that have a no-energy-exchange property between all the waves. They are shown to exhibit cross-induced nonlinear refraction and to be ideal candidates for amplitude-dependent phase control in χ⁽²⁾ materials that emulate nonlinear refractive-index effects in third-order [χ⁽³⁾] materials. It is shown that all these eigenmodes are spatially stable.
