Strong coupling of exciton polaritons in laterally structured organic microcavities — •Tony Henseleit1,2, Markas Sudzius1,2, Harmut Fröb1,2, and Karl Leo1,2 — 1Dresden Integrated Center for Applied Physics and Photonic Materials — 2Technische Universität Dresden
Strong coupling in inorganic semiconductor materials has been investigated for many years with rising interest in strong coupling in organic materials. The realization of strong coupling at room temperature leads to possible applications as for example polariton lasing and enables investigation of many other interesting physics such as polariton blockade effects.
A polariton is a quasi particle comprising of a photon coupled to an exciton. We are focusing on exciton polaritons in layered resonator structures with organic active materials. We investigate organic materials at room temperature in strong coupling regime and can report to see a reasonable large splitting of the cavity mode in our spectroscopic studies. Furthermore we are especially examining the influence of lateral periodic submicrometer structures on strongly coupled polaritons. This results in an additional confinement of the particles in the system and forms for example waveguide modes in the structure.
