Molecular strong coupling is a versatile method for controlling the energetic behavior of light-matter interactions. For example, it is a promising method for designing new type of laser like light sources through the process of non-equilibrium Bose-Einstein condensation (BEC), to control and to direct photo-chemical reactions and to manipulate the molecular energy transfer processes beyond the distance set by the Förster resonance energy transfer (FRET) etc. Although many application ideas exist, further understanding is needed for designing of such new and potentially useful systems.
Here I give a brief introduction on the application specific geometries for achieving strong coupling with molecular excitations and confined optical fields. I will also discuss our current activities and experimental and numerical simulation capabilities in the field at the Institute of Physics at the University of Tartu. The scientific focus of my research is the understanding of the role of the Stokes shift in the energy transfer processes and efficiency in polaritonic luminescence and light sources.
