We present theoretical considerations of systems of spherical Mie semiconductor scatterers. The scatterers display nonlinear characteristics in the optical spectrum and they are embedded in a matrix which exhibits also nonlinear response properties. We discuss the in consequence of various non-linearities on the response to ultra-short pump pulses. We focus especially on higher order Mie-resonances and their interplay with nonlinear response properties of the system. We consider Kerr non-linearities and also frequency conversion with and without optical gain. The possibilities of utilizing this behavior in applications are discussed.
