Experimental and theoretical investigation of microresonators at Jena University

In this talk, we present our recent results on investigations of microresonators at the University Jena. The work is divided into two parts. In the first part we focus on fabrication and characterization of different nonlinear effects in single silica and hybrid silica-silicon disc microresonators. In the second part we discuss spectral characteristics and light distribution in coupled micro disc resonators as a function of coupling strength and symmetry. The experimental results have been confirmed by theoretical calculations using an exact model based on Mie theory.
