Title

Interaction Phenomena In Second-Order Nonlinear Materials

Abstract

During the past three years, interest has grown rapidly in the theoretical and experimental study of solitary waves in materials with second-order nonlinearities, especially after they were experimentally observed in geometries with one or two transverse dimensions. A stable solitary wave consists of both a strongly coupled fundamental and harmonic beam. When two such solitary waves interact, it has been shown that the behavior of the output solitary waves is strongly influenced by the relative phase between the two input solitary waves and can generate, in the same material, phenomena similar to those predicted for self-focusing or self-defocusing Kerr materials, as well as saturable Kerr materials. However, in a real application/experiment, only fundamental waves will be launched and the interaction of interest will occur during or subsequent to the evolution into spatial solitary waves. In this case, the solitary wave is excited in two steps: generation of the second harmonic followed by a series of slow oscillations as the two pulses reshape into a solitary wave. This paper focuses, on the dependence of the interaction of the two pulses on the reshaping oscillations.
