SHCHERBAKOV, A.S.  y  AGUIRRE LOPEZ, A.. Optically pumped generation of multi-pulse three-wave coupled states in a two-mode waveguide with a square-law nonlinearity and digital modulation of light. Rev. mex. fis. [online]. 2008, vol.54, n.5, pp.368-375. ISSN 0035-001X.

We study the process of sculpturing three-wave weakly coupled states under the action of the pulsed optical pump in a two-mode square-law nonlinear waveguide within the collinear regime of propagating the interacting waves. The analytical model for this process with slightly mismatched wave numbers predicts the sculpturing of multi-pulse optical components inherent in three-wave coupled states. Reasoning from the developed approach, we discuss an opportunity for the digital modulation of light, because those potentially three-wave coupled states under consideration can be binary encoded. The performed analysis of sculpturing multi-pulse coupled states in a non-stationary regime was experimentally examined during our studies of collinear acousto-optical interaction in a two-mode lithium niobate waveguiding structure exhibiting a square-law nonlinearity.
