Utilizing Nonlinearities in Mie-scattering Systems — •Andreas Lubatsch1 and Regine Frank2 — 1Electrical Engineering, Precision Engineering, Information Technology, Georg-Simon-Ohm University of Applied Sciences, Kesslerplatz 12, 90489 Nürnberg, Germany — 2Institute for Theoretical Physics, Eberhard-Karls University Tübingen, Germany Center for Light-Matter-Interaction, Sensors and Analytics (LISA+) and Center for Complex Quantum Phenomena (CQ)
We present theoretical considerations of systems of spherical Mie semi-conductor 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 influence of these 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.
