There has been much recent interest in cascaded nonlinearity because it enables phenomenafamhr in Kerr mediato be observed in quadratic media. Cascading has mainly been considered in Type I geometry. which mimics a. scalar ,p). Here we consider Type I1 cascading, which corresponds to a wetor Kerr effect. This is especially interesting because i t leads to pure cross-modulation of the two polarisations of the fundamental field. We predict that in the presence of diffraction this mechaoism leads… CONTINUE READING
