Competing nonlinearities in quadratic nonlinear waveguide arrays

Setzpfandt, Frank; Neshev, Dragomir N; Schiek, Roland; Lederer, Falk; Tünnermann, Andreas; Pertsch, Thomas

Description

We demonstrate experimentally the existence of competing focusing and defocusing nonlinearities in a double-resonant system with quadratic nonlinear response. We use an array of periodically poled coupled optical waveguides and observe inhibition of the nonlinear beam self-action independent on power. This inhibition is demonstrated in both regimes of normal and anomalous beam diffraction.
