- Three-wave interaction in two-component quadratic nonlinear latticesPublication . V. V. Konotop, V. V.; Cunha, M. D.; Christiansen, P. L.; Clausen, C. BalslevWe investigate a two-component lattice with a quadratic nonlinearity and find with the multiple scale technique that integrable three-wave interaction takes place between plane wave solutions when these fulfill resonance conditions. We demonstrate that energy conversion and pulse propagation known from three-wave interaction is reproduced in the lattice and that exact phase matching of parametric processes can be obtained in non-phase-matched lattices by tilting the interacting plane waves with respect to each other.
