Nonlinearity-induced asymmetric diffraction in a hybrid A/B structure with two azo-containing materials

Nonlinearity-induced asymmetric diffraction based on spatial self-phase modulation is demonstrated experimentally through the illumination of a focus Gaussian laser beam on azo-containing materials coupled together with an A/B structure. We report here that symmetry breaking occurs to the intensity...
